Do you ever wonder why you can still see the contents on your smartphone screen even on a sunny day? That's what the nits in your device are made for. But even though there's a chance you own at least one tablet or a smartphone, you may still be unfamiliar with nits and the technical jargon that comes with it.

With that said, knowing how to measure it and finding the ideal amount of nits ensures that you have a bright display suitable for your device. So, what is a nit brightness, and why is it important? Moreover, how do you measure nits? If you have all those questions spinning in your head right now, here's everything you need to know about nits below.

Everything You Need to Know About a Nit

Before anything else, here's a basic definition of what a nit is. A nit is used in measuring luminance or the brightness in screens of laptops, televisions, tablets, and other devices with displays. Nit is actually an informal way of saying candela per square meter. On the other hand, luminance is all about how intense light can get.

And the greater the number of nits, the greater the luminance. Moreover, the word nit is most likely formed from the Latin word "nitere," which translates to "to shine" in English. Hence, it's probably why many users have accepted using the term nits when measuring the luminescence or brightness of a display.

How Bright is a Nit?

How bright is a nit, you may ask? The brightness of a nit is the equivalent of the light produced by one lit whale oil candle. Place that lit candle in a container that measures one meter at all sides, and the light that stretches to the surface of the container is the equivalent of one candela per square meter.

Furthermore, the Latin word "candela" translates to the word candle in English. So, you could say that one candela per square meter pertains to the light produced by just one lit whale oil candle placed in a one-meter by one-meter container. And by adding another lit whale oil candle in the same container, you get the equivalent of two candelas per square meter. You should get the idea by now.

Why Do You Need to Care About Nits Brightness?

Now that you know what a nit is and how bright one is, you must be wondering why you should even care about nits in the first place. So, why do you need to care about nits brightness? Well, that's because knowing how many nits a device has will help you find a device with a more luminescent display. For example, if you want a brighter television, you can specifically look for a TV containing more nits.

Furthermore, as stated at the beginning of this article, nits brightness aids you in clearly seeing the contents on your screen, even on a sunny afternoon. So, since you're definitely using your phone outdoors, it only makes sense to prioritize getting higher amounts of nits in portable devices like tablets, smartphones, laptops, and the like.

Differences Between Nits and Lumens

At this point, you must be wondering why you should use nits when the unit lumens already exists. Compared to nits, lumens is simply the generic term referring to the light yielded by a display. However, although the two terms have their differences, nits and lumens are related.

After all, lumens and nits are related in a way that one nit equals one ANSI lumen. An ANSI lumen pertains to the total light bouncing off a surface whose sides all measure one meter. Moreover, ANSI lumen is also much more used in the field of video projectors, while the term nit is just a new term that's recently been added in the world of televisions.

Furthermore, a single nit also contains a greater amount of luminescence compared to a single ANSI lumen. An estimate calculation also shows that a single nit also consists of an estimated amount of 3.426 ANSI lumens. And using that amount, you can find the present amount of nits or ANSI lumens in your device.

So, if you want to compute many ANSI lumens there are in your device, you can multiply your device's total nits to 3.426. Meanwhile, if you want to calculate how many nits your device has, you can use your device's total ANSI lumens and divide it by 3.426 to get its total amount of nits.

How to Measure Nits Brightness?

Most of the time, you can find information regarding your device's nits by looking up their product specifications from its manufacturer's official site, sheet specifications, etc. Detailed product reviews might also state how much nits a particular device as well. Alternatively, you can use available apps or software to help you determine your device's nits brightness.

Now, if you don't feel like downloading software or apps just to do so, you can also utilize tools to help you find out. One handy device for the job would be the digital lux meter. And after finding the lux amount of your device, simply make the necessary computations to get the nits brightness of your device's display.

One nit equals an estimate of 3.14159 lux. Use that amount and divide it by the result on your digital lux meter, and you should get the estimated number of nits your device's display contains.

What is the Ideal Nits Brightness?

Now that you're past the technicalities of a nit and know what it is, it's time for this critical question: what is the ideal nits brightness? To answer your question, the recommended number of nits varies depending on the type of display.

For instance, tablets and smartphones usually contain a minimum of 2 nits and a maximum of 1000 nits. Ideally, you should get tablets or smartphones with a minimum of 500 nits. If your mobile device has that amount of nits, they should be enough to use in bright rooms and the sunny outdoors.

The same thing goes for computer monitors or laptops, which usually have nits ranging from 200 to 600. On the other hand, televisions should have 600 or more nits for excellent display, especially for high dynamic range TV types.

About LED Shoebox Lightings

LED Shoebox Lightings provide an effective way to light up a large area with ease. They are pole mount  light fixtures found in parking lots and large outdoor areas. Current traditional styles like Metal Halide and High Pressure Sodium fixtures range from 400 Watts to 1000 Watts and can easily be replaced with LED Lights. They come in a myriad of power options which range from 50 watts to 500 watts and can produce up to 70,000 lumens. You can expect your lighting bill to reduced by 50% to 80% after you convert to LED.

Why are shoebox lighting plans important?

Led Shoebox Lightings Plans allow you to see your parking lot modeled inside software. The resulting Light Plan shows you how bright the area is and how well distributed the light is. Using the software, different types of lights, wattages, optics and mounting angles can be adjusted to find the optimal lighting for your parking light. A shoebox lighting plan will show you light levels (in foot candles or lux) and provide you with an indication of how even the lighting is. We can optimize the plan without you spending $1 on lights. This ensures success when you decide to move forward with you lighting conversion project.

How many lumens do I need when replacing my old shoebox lights?

To replace 400 Watt Metal Halide, consider fixtures between 15,000 and 25,000 (LED) lumens. To replace 1000 Watt Metal Halide, look for LED fixtures producing 40,00 to 55,000 (LED) lumens. Ultimately, the real answer lies in performing a shoebox lighting plan for your parking  or large area - which we provide for free. Metal Halide Shoebox to LED Conversion Traditional Shoebox Light LED Shoebox - Lumens (100% directional) 250 Watt Metal Halide 10,000 - 12,000 LED lumens 400 Watt Metal Halide 15,000 - 25,000 LED lumens 1000 Watt Metal Halide 40,000 - 55,000 LED lumens   What are the most common color temperature for outdoor led shoebox light fixtures? The two most popular color temperatures are 4000K and 5000K. 5000K is a good replacement for Metal Halide Shoe box lights. Many states have rules that only allows for 4000K or lower installed outdoors. In comparison, High Pressure Sodium lights are 2200K - 2300K. That is why everything under HPS appear yellow / brown.

What are the best optics to use in LED Shoebox Area Lights?

By far, the most common outdoor shoebox optics are Type 3 and Type 5. Type 5 optics are best used in the middle of a parking lot provides great area distribution. Type 3 optics are best used on the edges of a lot ensures the light ends up in the lot and not the area directly behind the shoebox fixture. If you are concerned about light trespass on the edge of your property, consider adding a fixture back shield.   Do LED Shoebox Lightings work with Lighting Controls? Yes, LED Shoebox lightings work well with photocells and/or motion sensors. Adding lighting controls is not only practical, it lowers light levels when no one is around. It saves more energy by reducing the light levels required  at any time during the night. And because LED Lights are instant on - instant off, they pair well with lighting controls. Are your shoebox lights in good condition? Consider a shoebox retrofit kit These shoebox retrofit kits can replace anything from 250 Watt to 1000 Watt Metal Halide and HPS. It's can be easily installed by a certified electrician - if they can do a bulb and ballast replacement, they can install these. Our Ultra High Efficiency Retrofit Solutions are DLC Premium Listed. This means you can qualify for a rebate from your utility company.

About Led shoebox Lightings

Led shoebox Lightings are smart lights that are designed with all the intelligent features like photocells and motion sensors. Led shoebox Lightings are a perfect replacement for metal halide lights. These lights are highly energy-efficient and long-lasting. These lights are highly used as LED Parking lot lights due to their various wattages, lumens, and color temperatures. Led shoebox Lightings are trending as they are energy-efficient, longer operational life, environment friendliness, and excellent illumination. Also referred to as street lights, shoebox lights, and area lights, Led shoebox Lightings help illuminate streets, parking lots, building entrances, gardens, hotel walkways, among other outdoor spaces. They provide adequate lighting, keeping the drivers and pedestrians away from accidents by providing ease of navigation throughout an area. At Bbier, we provide Led shoebox Lightings that feature sturdy materials and industry-standard IP ratings, which is a testament that they will last over half a decade without frequent maintenance.

Robust Unidirectional Area lights for Local Lighting in Large Outdoor Areas

LED Area lights from our collection feature a low profile. They are vibration-resistant and feature sturdy optics, which make them ideal for outdoor installation. Unlike traditional lights, LED lighting fixtures are unidirectional, which means that they put out light output in a fixed direction. The Area Lights that you’ll find in this collection offer a wide beam angle for covering a larger area. The extended area coverage and exceptional lumen output of our Led shoebox Lightings allow cutting down the number of fixtures that you’ll need to illuminate large outdoor spaces.

Essential Features to be Considered for Led Shoebox Lightings:

- Wattage– Depending on the area you want to cover, opt for the right wattage ranging from 15 watts to 300 watts. - CCT– Defines the glowing colour of light, whether a warm or cool effect ranging from reddish-orange to a cool white or bluish color. - CRI– Colour rendering index is the rating system that indicates the level of illumination. The higher the rating, the light will be closer to the natural light. - Heat Dissipation– The LED fixture's enclosure should help control heat, and it has excellent heat dissipation.

Types Available

Bbier is a one-stop-shop for all your outdoor lighting needs. We provide Led shoebox Lightings in several color options: Bronze, Gray, Black, Silver, and White. The wattage options that we have in stock are 35W, 55W, 150W, and 300W. Furthermore, you can also choose from various mounting options, depending on the mounting pole. If you are worried about the utility bills, don’t. In comparison with conventional fixtures, LED lights consume little energy. They are known to bring down energy consumption by up to 80%. Furthermore, attaching Photocell Sensors (dusk to dawn sensors) can help monitor energy usage by automating the ON/ OFF process.  

Adaptove and Protective Controls

The groundbreaking technology of LED lights comes with greater flexibility because of which the dimness can get adjusted correctly. The motion sensors detect the motion, which makes the light adjustment automatic. Once the sensors stop detecting motion, the light tones down to their low mode, and after the fixed default period, it ultimately gets switched off. Another option for control is a photocell that directs lights to turn on and off depending on ambient light. Opt some of these innovative controls for being energy efficient and to conserve energy if there is no need.

Mounting Options

There are particular mounting options available for LED Parking Lot Lights, depending on the light type. The sturdy mounting option we have for you is yoke-mounting (YM), adjustable-mounting (AM, also known as slip fitter), direct-mounting (DM), and universal-mounting. - Yoke-Mounting: Yoke mounting is a simple and durable mounting solution used for mounting lighting fixtures to any vertical surface, although it allows a full tilting range of motion. - Direct-Mounting: This type of mounting can be used for mounting a lighting fixture on either a round or a square pole that allows you to illuminate your property's outdoor areas with ease. - Universal Mount: Universal mount is the type of mounting that enables you to install lighting fixtures in any desired location, be it a yoke, adjustable slip fitter, knuckle mounting, or just a bare wall. - Adjustable-Mounting: Adjustable Mounting is also called Slim Fitter Mount. It is used for mounting LED lights in a round pole and allows you to adjust the inclination angle from 90 degrees to 180 degrees to provide you a versatile lighting experience.

Accessories Required

We also have Tenon Adaptors and Bullhorns, that are suitable for wooden, metallic, or concrete poles in square or round shapes. Our accessories line for Led shoebox Lightings includes photocell Sensors, motion sensors, and Always ON Shorting Caps. Choose the right LED accessory, and you’ll be able to enhance the usability, functionality, and performance of the outdoor pole light installations. LED shoeboxes are an efficient, modern way to replace metal halide and high pressure sodium (HPS) lamps for outdoor applications. LED shoeboxes are great for lighting areas like parking lots, outdoor walkways and public parks.

What Mounting Options are Available for Shoebox Fixtures?

Three styles of mounting arms are generally available. They are: Direct Mounts: A direct mount allows you to attach your shoebox directly to an existing pole. That means direct mounts are the easiest way to switch over your existing HPS or metal halide lights to LED. Installation will involve wiring your light and then attaching the shoebox to the pole using bolts. That simplicity is a major advantage of direct mounts, but it’s important to know that they’re also generally short and designed to be installed in one particular orientation . That means they don’t provide the flexibility of some other mounts. Slip Fitters: As their name implies, slip fitters slip on top of a pole rather than being bolted onto the side (like a direct mount). Wiring feeds all the way up the pole, through the mount, and into the back of the lamp. The main advantage of slip fitters is that they are generally hinged, allowing the lamp to be tilted, pitched, and adjusted. Slip fitter mounts are ideal for situations in which you’re trying to focus light in a particular area or working in a challenging space. Trunnion Mounts: A trunnion mount is a hinged, square frame made of thin metal. Wiring a trunnion mounted LED shoebox involves threading insulated wires through that frame and into the back of the lamp. Trunnion mounts are highly versatile and can help you fit powerful lamps into tight spots and direct your beam in a directional manner to achieve lighting goals. Unlike direct or slip fit mounts, trunnions do expose some wiring to the elements, so they do require some increased maintenance.

Light Distribution Patterns for LED Shoeboxes

Not all lamps achieve the same lighting effects. That’s additional true for LED lamps, which are directional in nature. - Type I: Type I LEDs create a long, narrow, flying saucer shaped light pattern. These are most commonly used for walking paths, sidewalks, bike trails, and other narrower areas. - Type II: Type II LEDs cast a long oval of light that’s ideal for alleys and smaller roads. Positioned over the edge of a narrow road, a Type II LED can illuminate the entire width of the road and both shoulders. - Type III: Type III lamps create a shorter, wider, more circular oval of light than their Type II counterparts. They are frequently used in parking lots or to create more light on the edges and shoulders of a road. - Type IV: Unlike Types I, II, and III, Type IV LEDs do not create a symmetrical field of light. Instead, they create a semicircle, reaching far in front and to the sides of the lamp while providing almost no light behind. Type IVs are useful for bringing additional light to a particular side of a road, public space, or parking area. - Type V: Type V LEDs provide an omnidirectional circle of light. The radius of that circle is far tighter than the reach of any of the previously mentioned types, but within that circular area, the light is bright and clear. Type V LEDs are great for use in the middle of parking lots or at intersections. - Type VI: Type VI LEDs (sometimes called “Type VS”) create an omnidirectional square of light. This creates a highly symmetrical field with near equal foot candles in almost every part of the field. Like Type Vs, Type VI LEDs are excellent at areas where traffic comes together (like on ramps, intersections, etc.) as well as large parking lots.

LED Shoebox Features to Consider

IP Rating The IP (Ingress Protection) rating of your shoeboxes will determine just how tough and durable they are. IP ratings are two digit numbers: the first digit represents the fixture’s ability to protect your lamps from dust on a scale of 0 – 6 (with 6 being the best). The second digit represents protection from moisture on 1 – 8 scale (with 8 being the best). Since dust (from cars, the roadway, exhaust, etc.) and moisture (from rain, snow, cleaning, etc.) both have the potential to affect outdoor lights, you need to shop with IP rating in mind. Generally, a 65 (completely dust tight and protected against jets of water like from a power washer) is an ideal IP rating for an LED shoebox. Photocell Sensors Photocell sensors, also known as “dusk to dawn sensors,” help exterior LED lights shine only when an as much as is needed. That can lead to up to a 50% energy savings per lamp for you! If you’re switching your HPS or metal halide lamps over to LED to take advantage of the increased efficiency, you’ll definitely want to make sure they have dusk to dawn sensors installed to maximize your returns. Dimmability Dimmability is another one of the features that make LED lamps so attractive, efficient, and inexpensive over the long term. Not all LED shoeboxes are necessarily dimmable, though, so when you’re shopping, be sure to look out for products clearly marked “Dimmable.”

Full Spectrum LED Grow Lights: The Truth You Need to Know

Many LED lighting suppliers will say that full-spectrum LED grow lights are the best option for growing plants because they mimic the natural light from the sun. The argument goes:

“Plants have grown under sunlight for millions of years. Why would we want to change what mother nature knows is best?”

Well, we want to let you know that there is no such thing as a full-spectrum LED grow light.

There, we said it.

But before we get a flood of messages from concerned growers wondering what all the confusion is about, let’s first uncover what full spectrum means. Then we’ll let you in on the truth about full-spectrum LED grow lights so you can make the best grow light choice for your facility.

What is a Full-Spectrum LED Grow Light?

A full-spectrum LED grow light is simply a marketing term that implies that your grow light closely resembles light from the sun. This marketing term comes from the concept of “full-spectrum light,” which in recent years has been used to refer to electromagnetic radiation from the UV to infrared wavebands.

The History of the Full-Spectrum LED Grow Light

The full-spectrum commercial LED grow light is the newest evolution of an already confusing term. Originally, full-spectrum light described the only real full-spectrum light source, the sun.

Over time, the term began to take on other characteristics of sunlight. The commercial lighting industry began using the name “full-spectrum” to sell lights that produced a Color Rendering Index (CRI) over 90. Humans perceive colors more accurately under light sources with a CRI over 90, much like how we see colors in our natural world under daylight. This was a beneficial feature for human environments such as offices, outdoor spaces, and others.

With the advent of horticultural lighting, companies once again began to borrow the term. Only this time, they claimed that full-spectrum LEDs could reproduce the effects of sunlight for plants.

Thus, the full-spectrum LED grow light was born. Unfortunately, lighting for plants is not quite that simple.

Problems with Full-Spectrum LED Grow Lights

There are many issues with the concept of full-spectrum LED grow lights. For starters, just because you name something, doesn’t make it true. This rhetoric may have made sense for lighting designers interested in selling lights so humans could see, but plants require light to feed, grow, and live.

There are three major problems when talking about full-spectrum grow lights:

Full-Spectrum Grow Lights Aren’t Optimized for Plants

Full-Spectrum Grow Lights Don’t Include the Full Solar Spectrum

Full-Spectrum Grow Lights Are Not Dynamic Like the Sun

We’ll briefly look at these problems with full-spectrum grow lights one-by-one, so you can understand how deep the roots of this problem run:

1. Full-Spectrum Grow Lights Aren’t Optimized for Plants

A major problem with many full spectrum vertical grow light is that they are designed to give the appearance of daylight without being custom-tailored for rigorous plant growth.

It’s the reason why we at LumiGrow coined the phrase, “PAR is for plants and Lumens are for humans.” Not all wavelengths of light are optimal for photosynthesis. Plants photosynthesize electromagnetic radiation in the 400 to 700 nanometer range, known as Photosynthetically Active Radiation or PAR. So, plants don’t care how bright your light fixture appears to you.

Still, most full-spectrum lighting companies build fixtures with this visual appeal in mind.

When you hear that the diodes in your full spectrum grow light are 3,000k to 4,500k, or 5,000k+, this degree of Kelvin (K) refers to how “cool” or “warm” your light is in appearance.

Our understanding of plant photobiology has come a long way. We understand much more about plants than to be using human lighting metrics to design our grow lights.

Our goal as growers is to improve the lighting characteristics most important for plant growth. This means not only getting enough PAR light, but also the right mix of light spectra, which brings us to problem #2.

The thinking behind many full spectrum LED grow lights on the market is that by creating a spectral distribution similar to sunlight, your plants will grow well. A decent theory, except that full spectrum grow lights are not actually similar to the sun.

We can see below that the sun’s radiation includes much more than the visible or PAR wavebands.

Sunlight itself is complex, and many scientists are still working to understand it today. You can see that sunlight also contains ultraviolet (UV) and infrared light (as well as x-rays, radio waves, and others, but we’ll leave those alone for now).

Although PAR is the most important light for photosynthesis, plants still respond to radiation outside of the PAR spectrum. For instance, UV light elicits protective compounds in plants similar to the way humans become tanned in the presence of UV.

Plants also use a type of infrared light called “far-red light” to induce a shade avoidance response, causing them to stretch and can induce early flowering.

To create a light source that elicits plant response the same way the sun does would be too costly and downright impossible given current grow light technology. Nor would you want to create such a grow light, which takes us to problem #3.

3. Full-Spectrum Grow Lights Are Not Dynamic Like the Sun

Not only would it be too costly to create an actual full spectrum quantum board grow light, but if such a thing even existed, its performance would still not accurately reflect what’s happening in nature.

The sun’s spectrum is in constant flux due to changes in weather or its position in the sky relative to earth. In the graphic above, you can see how sunlight spectra change throughout the day or in different weather conditions.

Because of this phenomenon, it’s best to think about the interaction between sunlight and plants as a continually changing process.

If you hang your full spectrum grow lights in a greenhouse, you will still reap the benefits (and disadvantages) of this natural process from the sun. But if you take those same full-spectrum lights and hang them indoors, they will not behave like the sun.

Photomorphogenic responses by plants are co-regulated, which means that certain expressions of the plant may turn on or off based on the amount of light within one waveband relative to another.

Photosynthesis depends upon the absorption of light by photoreceptors and pigments in the leaves of plants. The most well-known of these pigments is chlorophyll-a, but there are many accessory pigments that also contribute to photosynthesis.

The relative light absorption of chlorophyll pigments as shown in the graph to the right is one of the reasons why red light has become popular among LED grow lights. Not all PAR light contributes to photosynthesis equally, though we now understand that other wavebands of light such as green, do play an important role in this process.

Since photoreceptors in plants also have their own ranges for light absorption, they co-regulate processes that create plants’ form and structure depending on the spectral mix they receive.

For instance, higher ratios of blue light can induce more robust root growth, more favorable plant biochemistry, and a hardier structure. But these effects may not be as pronounced when more red light is introduced.

Thus, the ever-changing spectrum of the sun is constantly signaling to plants to change their form and structure based on the natural conditions of the environment.

But before you rush and begin moving your grow room outdoors, let’s consider why plants don’t need the full spectrum of sunlight. For starters, plants don’t need UV or infrared light to live. Also, in a controlled environment, plants are given ideal conditions to grow in and often don’t need to compete with other species to live.

Plants only require light in the 400 to 700-nanometer range to photosynthesize. So, you’ll want to choose a grow light that produces your desired results, most often higher yields and better quality for your plants.

What is the Best Light Spectrum for Plant Growth?

By now you must be wondering:

“If I can’t mimic sunlight, then what light spectrum should I use?”. The answer is both simple and quite complex.

Plants only require PAR light for photosynthesis. So, if your grow light is optimized within the PAR spectrum, you’re going to get the most bang for your buck when it comes to minimizing electrical costs while maximizing plant health.

Beyond PAR, it’s important to choose a light spectrum that’s:

best for the environment you’re growing in (greenhouse or indoors)

tailored to your plant’s growth phase (propagation, vegetative, flowering, or finishing)

or specific to the cultivar being grown

Full Spectrum LED Grow Lights vs. Other Grow Light Options

It should be clear by now that there are no real standards around full samsung lm301b grow light. Full-spectrum is simply a term used to sell you a simple idea.

Although you cannot mimic sunlight, you can use light spectrum to your advantage.

Luckily, there are many grow lights available with designs intended to do just that. So, let’s uncover your options so you can pick the best grow light for your cultivation.

Narrow Spectrum LED Grow Lights

Narrow-spectrum LED grow lights use a higher ratio of narrow-band LEDs. These grow lights most often have a pink or purplish hue since they are optimized for the blue and red PAR wavebands.

These types of pink grow lights have been popular since the early days of LEDs for horticulture. Though this doesn’t mean they are outdated by any means.

In greenhouse environments a narrow spectrum is almost always desired. The sun already fills out a full spectrum, so it makes sense to put most of your energy into wavelengths that are most optimal for photosynthesis.

Also, because of the added efficiency of red diodes versus other colors, you will get more bang for your buck when it comes to energy efficiency.

Broad-Spectrum LED Grow Lights

Broad-spectrum LED grow lights have a higher ratio of broad-band LEDs. These lights are white in appearance, though there are no actual white wavelengths. The white hue is a mix of blue, red, and green wavebands.

These grow lights also don’t claim to mimic the sun, but they will effectively replace the sun to drive high yields and premium quality in any environment.

Our broad-spectrum has been enriched with red and blue peaks to drive robust photosynthesis and plant structure while emphasizing the green waveband to be versatile with any crop type or cultivation environment.

Recommended for indoor environments, except in specialized cases where narrow-band lighting is preferred.

Adjustable Spectrum LED Grow Lights

These modern LED grow lights allow for precision control of your plants. By adjusting your grow light spectrum wirelessly, it’s possible to speed up flowering times, improve your plant’s biochemistry, or customize your plants’ structure to root better and be more easily managed.

Learn About LED Lighting

What are LEDs and how do they work?

LED stands for light emitting diode. LED lighting products produce light up to 90% more efficiently than incandescent light bulbs. How do they work? An electrical current passes through a microchip, which illuminates the tiny light sources we call LEDs and the result is visible light. To prevent performance issues, the heat LEDs produce is absorbed into a heat sink.

Lifetime of LED Lighting Products

The useful life of LED lighting products is defined differently than that of other light sources, such as incandescent or compact fluorescent lighting (CFL). LEDs typically do not “burn out” or fail. Instead, they experience ‘lumen depreciation’, wherein the brightness of the LED dims slowly over time. Unlike incandescent bulbs, LED “lifetime” is established on a prediction of when the light output decreases by 30 percent.

LEDs are incorporated into bulbs and fixtures for general lighting applications. Small in size, LEDs provide unique design opportunities. Some LED bulb solutions may physically resemble familiar light bulbs and better match the appearance of traditional light bulbs. Some outdoor LED light fixtures may have LEDs built in as a permanent light source. There are also hybrid approaches where a non-traditional “bulb” or replaceable light source format is used and specially designed for a unique fixture. LEDs offer a tremendous opportunity for innovation in lighting form factors and fit a wider breadth of applications than traditional lighting technologies.

LEDs and Heat

LEDs use heat sinks to absorb the heat produced by the LED and dissipate it into the surrounding environment. This keeps LEDs from overheating and burning out. Thermal management is generally the single most important factor in the successful performance of an LED over its lifetime. The higher the temperature at which the LEDs are operated, the more quickly the light will degrade, and the shorter the useful life will be.

LED products use a variety of unique heat sink designs and configurations to manage heat. Today, advancements in materials have allowed manufacturers to design LED bulbs that match the shapes and sizes of traditional incandescent bulbs. Regardless of the heat sink design, all LED products that have earned the ENERGY STAR have been tested to ensure that they properly manage the heat so that the light output is properly maintained through the end of its rated life.

LED lighting differs from incandescent and fluorescent in several ways. When designed well, LED lighting is more efficient, versatile, and lasts longer.

LEDs are “directional” light sources, which means they emit light in a specific direction, unlike incandescent and CFL, which emit light and heat in all directions. That means LEDs are able to use light and energy more efficiently in a multitude of applications. However, it also means that sophisticated engineering is needed to produce an LED bulb that shines light in every direction.

Common LED colors include amber, red, green, and blue. To produce white light, different color LEDs are combined or covered with a phosphor material that converts the color of the light to a familiar “white” light used in homes. Phosphor is a yellowish material that covers some LEDs. Colored LEDs are widely used as signal lights and indicator lights, like the power button on a computer.

In a CFL, an electric current flows between electrodes at each end of a tube containing gases. This reaction produces ultraviolet (UV) light and heat. The UV light is transformed into visible light when it strikes a phosphor coating on the inside of the bulb. Learn more about CFLs.

Incandescent bulbs produce light using electricity to heat a metal filament until it becomes “white” hot or is said to incandesce. As a result, incandescent bulbs release 90% of their energy as heat.

Why should I choose ENERGY STAR certified LED lighting products?

There are more lighting options available today than ever before. Despite that, ENERGY STAR is still the simple choice to save on your utility bills.

LED bulbs that have earned the ENERGY STAR are subject to very specific requirements designed to replicate the experience you are used to with a standard bulb—so they can be used for a wide variety of applications. As the graphic on the right demonstrates, a general purpose LED bulb that does not qualify for the ENERGY STAR may not distribute light everywhere and could prove to be a disappointment if used in a table lamp.

The potential effects of LED street light on health and the environment have been a hot topic of discussion over the last year. As this conversation has evolved, so too have many misperceptions and mischaracterizations of the facts on LEDs. We’ve assembled an array of helpful resources on the topic to help shed some light  and are clarify some of the most common myths on LED streetlights.

LED streetlights are no more harmful to humans and animals than other kinds of streetlights. The concern is not the type of light source, but the amount of emitted light that falls in the short-wavelength, often referred to as the “blue” part of the spectrum. And, unlike other types of streetlights, LED streetlights actually offer the potential to control the amount of short-wavelength light that they emit.On the contrary, short-wavelength light is a fundamental component of the natural world. It’s present in sunlight and has been shown to play an important role in a number of physiological processes, such as affecting circadian rhythm (our 24-hour “biological clock” that controls sleep/wake cycles). The concern is that too much nighttime exposure to short-wavelength light may disrupt sleep patterns and have other undesirable effects.It’s true that early LED lighting products tended to have greater levels of short-wavelength content because the technology was still in its initial stages of development. Tremendous advances since then, however, mean that today’s LEDs can be designed to emit as little, or as much, short-wavelength light as desired, without excessive drop-off in efficiency or other aspects of performance. LEDs also offer much greater control over where the light falls. This means they can often meet the same illumination requirements as conventional streetlights while emitting much less light – thus reducing even further any short-wavelength content.

Floodlighting has become an important part of security for homes and businesses alike. Whether connected to a motion detector or for use to light a garden at night, flood lighting has become an integral part of security in today’s society.

Homeowners and businesses have enough to deal with in these harsh economic times than needing to worry about changing floodlights. That’s why LED Flood Light offer the client not only an exceptional dispersion of light but also a bounty of advantages, which are only available when you use LED Floodlights.

One of the best advantages of using LED Floodlights is the life expectancy; they last for thirty times longer than standard halogen floodlights. This reveals a variety of advantages: you will have more free space as you would not need to stock up on replacement halogen bulbs. Also the main power involved in swapping out defective halogen bulbs can be time consuming and expensive, especially if running a business which requires the use of floodlighting. Thus purchasing LED Floodlights works to be extremely cost effective for the client. LED Floodlights repay your investment with longer life and an exceptional reduction in electricity costs.

With rising utility prices everyone is looking to save money. Through switching to an LED Floodlights customers will see a fall in their electricity consumption and in turn bills. The LED Floodlight will consume a significantly reduced number of watts compared to a halogen Floodlight, providing the client with an exceptional visual performance as well as low cost electricity bills. LED Floodlights feature economical illumination technology. This technology is also known as Light Emitting Diodes (LED light bulbs); this allows you to have exceptional brightness with a low power consumption.

LED Floodlights have a higher lumen output than standard Floodlights. One LED Floodlight can have the same effect as two or even three standard Floodlights. This is a staggering statistic and it means that with the longer life expectancy and the exceptional brightness less room would be needed for storing your existing halogen equivalent floodlights. It also now means that security for your home and business is now affordable and is most importantly cost effective.

It is important to note when looking to install floodlights for outside use that they are IP65 rated. This means that they have been designed and tested to withstand weather conditions and are safe for outside use. This special rating of IP65 is not to be overlooked as it is essential to the performance of the light when used outside.

Portable floodlights are also available on the market and our ideal for workers at night. By incorporating a battery to floodlights workers can experience high quality LED lighting by only consuming a fraction of the electricity of an ordinary halogen floodlight. This has many advantages such as safety for the workers as a clear bright illumination. Also these would need to be IP65 rated also as even in the most testing weather conditions the clear, crisp light will continue to emit.

This article has shown the huge benefits which LED Floodlights can give compared to their halogen equivalents. So for a more cost effective approach to lighting with better lighting results, make sure you choose LED technology when you purchase your next Floodlights.

In the world of lighting, LED high bay light is a fixture that you would find in a warehouse, a factory, a gymnasium, or any large open area with relatively high ceilings. Many existing high bay lighting and low bay lighting applications utilize high intensity discharge (HID) lamps such as metal halide or high pressure sodium lamps.

Despite their widespread use, HID lamps utilize antiquated technology that costs building managers both directly and indirectly. Specifically, using HID lamps will result in: higher than necessary energy costs, frequent maintenance costs, and poor lighting performance. These issues can all be addressed by converting your existing lighting to LED.

Energy Savings

Energy savings is a primary driver behind why you should evaluate LED lighting for your building or facility. Common wattages for LED high bay fixtures can range from 95 watts to 495 watts. If we compare this wattage to a typical HID high bay fixture that same range is 175 watts to 1000 watts.

Consequently, by switching to LED lighting you are immediately reducing your energy consumption by 40%-60%. To put this in dollars, you would be saving $300 per fixture per year in electricity costs if you made the switch to LED lighting. Depending on the size of your facility this can really affect the operational balance sheet.

Maintenance Cost Reduction

By converting to LEDs you will also see a dramatic reduction in the maintenance of your high bay light fixtures. This is due to the way LEDs generate light, and the way they progress through their functional life. Instead of ceasing to function properly once a fuel source is significantly reduced, LED generated light output degrades very slowly over time. As a result, the functional life of an LED product can be significantly longer than that of a HID Lamp, therefore drastically reducing the maintenance load required.

For example, by converting conventional 400w HID high bay lighting to LED, a typical building with industrial light fixtures can save up to $5,341 over the course of three years in maintenance costs alone.

The outdoor lighting industry, as with so many other application-oriented industries, assumes that the power source is infinite and always available. This is a tribute to the reliability of the electric grid - at least in developed-world nations. It has certainly made life simpler for the lamp/lighting designers who, for the most part, are able to divorce the lamp characteristics from the energy source. The developed world is starting to learn that the power source is far from infinite.

Some companies are not waiting to see the bottom of the barrel, and are exploring alternatives that range from replacement power sources to energy demand reduction. A number of companies are developing technologies that achieve both: SolarOne Solutions' work in solar-powered solid-state lighting under the SOLED? brand name is an example of this.

Solar-powered lighting

Solar electric lighting systems do in fact connect to a truly "infinite" power source - the sun. However, as we all know, this source is intermittent. In the case of solar outdoor lighting, the power source is inversely related to the load (the lights turn on when the sun goes down). This relationship leads to an important conclusion; the system must rely on energy storage (e.g. batteries), unless it remains connected to grid.

Now in order for a solar lighting system to perform reliably, the solar panel and battery must be sized for the period of longest nights, shortest days and cloudiest weather, all of which occur at the same time each year (see figure 2). Historically, the solar industry has addressed this worst-case scenario by seeking out the most efficient lumen per watt DC lamps and over-sizing the system for the rest of the year. That translated to DC fluorescent bulbs, bigger solar panels, more batteries, higher costs and less-than-appealing appearance.

This approach confined the market for solar LED light to areas closer to the equator with highest average levels of solar irradiation and temperatures that did not affect the performance and lifetime of the DC fluorescent bulbs. It also left the markets in the higher latitudes, typically with higher per capita wealth levels and greater lighting needs rather under-served.

Advantages of LED Lights-Why should I use

Article 2Whether you’re a creator of lighting systems, a user, or an installer, what is presented in this post is interesting for you. Designers, you will be made informed of the features of the next-generation luminaires, those which in addition to competence also produce the good light, the light we demand. You will discover what highlights a LED lighting arrangement must include suiting your needs avoiding harm to your well-being or that of your family. And

LEDs generally consume very low amounts of power. The statistics to look for when comparing the energy efficiency of different lighting solutions are called by one of two terms: luminous efficacy or useful lumens. These two items essentially describe the amount of light emitted per unit of power (watts) consumed by the bulb. In our experience, most LED lighting retrofit projects result in a 60-75% improvement in the overall energy efficiency of the facility’s lighting. Depending on the existing lights and the particular LEDs installed, the savings could be more than 90%. 

 Improved Safety with LEDs:

Safety is perhaps the most often overlooked advantage when it comes to LED lighting. The number one hazard when it comes to lighting is the emission of heat. LEDs emit almost no forward heat while traditional bulbs like incandescents convert more than 90% of the total energy used to power them directly into heat. That means only 10% of the energy powering incandescent lights is used for light (which also makes them extremely inefficient compared to LEDs). Additionally, because LEDs consume less power they can operate effectively on low-voltage electrical systems. These are LED Light Lifespan: Easily the most significant advantage of LEDs, when compared to traditional lighting solutions, is the long lifespan. The average LED lasts 50,000 operating hours to 100,000 operating hours or more. That is 2-4 times as long as most fluorescent, metal halide, and even sodium vapor lights. It is more than 40 times as long as the average incandescent bulb.

Less frequent replacement means two big things: lower maintenance costs in terms of labor and lower costs for replacement parts (because the bulbs simply do not fail for a long time).

LED Energy Efficiency:

generally much safer if something goes wrong.

LED Lights are Physically Small: The actual LED device is extremely small. Small power devices can be less than a tenth of a single mm2 while larger power devices can still be as small as an mm2. Their small size makes LEDs incredibly adaptable to an infinite number of lighting applications. Different uses for LEDs include a wide spectrum from their roots in circuit board lighting and traffic signals to modern mood lighting, residential, and commercial property applications, and even major stadium lighting. You can read about the history of LED lighting here or the history of lighting in general here. 

LEDs Have Great Color Rendering Index (CRI):

CRI is a measurement of a light’s ability to reveal the actual color of objects as compared to an ideal light source (natural light). High CRI is generally a desirable characteristic (although of course, it depends on the required application). LEDs generally have very high (good) ratings when it comes to CRI.

LEDs Generate Directional Emissions: LED technology emits light for only 180 degrees. Every other type of light emits light 360 degrees around the source. 360-degree emissions necessitate accessory devices to reflect and/or redirect the light. This drives up the costs for the system in general and inevitably results in losses meaning that the device is necessarily less efficient than it otherwise would be. Consider a light that emits light into the ceiling - that is your standard bulb. The problem is that you’re trying to illuminate the room, not the ceiling. LEDs solve this problem completely and give the savings back in terms of the system’s overall energy efficiency. 

LEDs Have Tremendous Design Flexibility:

Because LEDs are so small they can be used in virtually any application you can think of. They can be combined in bunches for a traditional bulb, used in isolation as a small device light, or strung out in sequence in a linear fashion. Just about everything you can think of can be done with LEDs.

LEDs are Solid State Lights (SSLs): LEDs are solid-state lights. This means that the traditional glass bulb surrounding the light is entirely unnecessary. 

LED Dimming Capability:

LEDs can operate at virtually any percentage of their rated power (0 to 100%). Of note, they do require hardware specific to LED technology to dim (meaning you cannot use the dimming equipment for an incandescent bulb or other traditional lighting technology). A positive of operating LEDs at less than full power is that they get more efficient as the power is reduced. This also increases the total lifespan of the light itself. Both of those advantages are absent with technologies like metal halides that get less efficient at lower power and in many cases cannot be dimmed at all.

LEDs Provide Instantaneous Turn On and Do Not Have Issues with Frequent Switching:

LEDs turn on and off instantaneously. There is no warm-up period like in the case of metal halide lamps. Additionally, frequent switching doesn’t cause degradation in the device. 

LED Lights are Environmentally Safe:

LEDs do not have the environmental issues common to traditional lighting solutions like fluorescent or mercury vapor lights. Both of these traditional solutions contain mercury internal to the bulb and thus require special handling at the end of the product’s useful lifespan. None of these considerations are necessary with LEDs.

LEDs Produce Virtually Zero UV Emissions:

LEDs emit the vast majority of their energy in the visible spectrum, a small amount in the infrared spectrum, and virtually none in the ultraviolet portion of the spectrum. This means that LEDs can safely and reliably illuminate UV-sensitive items like art that will break down and degrade over time if exposed to this type of emission. 

LEDs Operate on Very Low Voltage:

In many cases, LEDs operate on very low voltages. This makes them suitable for use in outdoor lighting applications where another lighting might not meet code such as with oceanfront homes where the ground level of the property is in a flood zone.

LEDs Operate Well in Cold and Hot Temperatures:

LEDs work well in a wide range of operating temperatures without significant degradation. 

Correlated Color Temperature (CCT):

LEDs are available in a wide range of correlated color temperature (CCT) values. They can be purchased with a “warm,” yellowish glow, as a “cool,” white light, and a variety of other options.

Whether you love camping because you enjoy the wilderness or just want to escape the imminent collapse of society, you'll want some electrical power while you're gone. It needs to be light enough to carry around, able to power small appliances, and should include a solar charge controller in case you're going to be out there for a while. An emergency light would be the icing on the cake.

Maxoak has exactly what you're looking for, with its Bluetti AC50S.

We're no stranger to Maxoak backup batteries here at MakeUseOf, having previously reviewed the massive EB240 and AC100. But those are difficult to carry around unless you have transport and more suited to use in caravans and cabins. At 13.5lbs, the AC50S certainly isn't lightweight but could still be heaved up a hillside without requiring a trip to the hospital.

With a total capacity of 500Wh, an AC converter, and a built-in MPPT solar charger, it'll go all day and then some.

Join us as we take a closer look at the AC50S, and thanks to Maxoak, we have two of these incredibly powerful emergency batteries to give away to two lucky readers. You'll find the competition entry form at the end of this review. 

But first, let's look at some of the standout features of the AC50S that make it perfect for camping and emergencies.

10W Wireless Qi Charging Pad

Your smartphone is probably the most important item you have during an emergency, so it's critical that you can keep it powered up. If you've lost or damaged the charging cable, you're in trouble.

Not so with the Bluetti AC50S, which includes a 10W wireless Qi charging pad on the top. To use it, turn on the main power and the DC output, then put your smartphone or tablet down (though some devices charge better when placed off-center, depending on where their Qi receiver is embedded).

Any smartphone from the last three or four years should be Qi-enabled, so this could be a real lifesaver. While it usually won't charge as fast as a cables, it's certainly more convenient.

Emergency SOS Flashlight

Built-in to the rear side of the AC50S is a large LED lighting panel. It features two brightness settings and an SOS mode. The exact lumens brightness isn't published, but the highest setting is bright enough to be painful to look at directly. The handle is positioned in such a way that the light can face forward when carried normally, so you needn't take a separate flashlight on your travels.

The SOS mode is something we hope you'll never need, but it's reassuring to know it's there if you do. In this mode, which operates at full brightness, the morse code for SOS is continuously repeated.

For either mode of operation, the AC50S must be powered on first, then the flashlight activated.

Bluetti AC50S Design

Measuring 11.6 x 7.5 x 7.7 inches and weighing 13.5lbs, the Bluetti AC50S sits at the extreme of what could be considered easily portable. The carry handle easily unfolds from its inset position in the lid and feels quite comfortable to hold without digging into your fingers. I would happily take this on a short hike, but hours of trekking around with it would certainly get tiring.

The corners of the AC50S are softened with a thin blue rubber bumper, and along with four rubber feet, ensure it can take the hustle and bustle of an outdoor camping trip without damage. It also means if you knock the relatively large device into your legs or waist when carrying it, the blow might be softened a little.

  Don't mistake these rubber bumpers for proper ruggedization, though. As with all large battery packs, the AC50S should not be thrown into a fire, pierced, shot, dropped off a cliff edge, or fed to a bear. The multiple power sockets and cooling grills also mean it isn't waterproof in the slightest. However, it is apparently made from flame retardent plastics, so you needn't worry about placing it in the general vicinity of a campfire. Not too close, though.

A clear dual-color LCD shows the remaining battery as five segments (each helpfully labeled in 20 percent increments), as well as the total wattage currently coming in and going out, with AC and DC reported separately. Though you're unlikely to hit the maximum 300W if you're only charging laptops and smartphones, this information does allow you to make a quick calculation of how long the battery will last.

Sockets, Ports, and Plugs Galore

Considering the diminutive size of the Bluetti AC50S, there's a bewildering number of sockets to be found.

There are four USB-A ports, each running at a maximum of 3A. Sitting above them is a single USB-C PD port, running at a maximum of 45W. This is slightly lower than most laptops' power requirements when running full speed but should be enough for light tasks or charging with the lid closed (if you didn't bring your AC adaptor, that is).

You'll find two small barrel-jack DC ports on the right of the display, running at 12V, 3A maximum. Further right of this is the regulated 12V car accessory port (or cigarette lighter, as we call it in the UK).

As we reviewed the UK model, you'll also see two three-prong UK plug sockets, which run at ~240VAC. A European model and US model is also available, running at ~110VAC. The maximum continuous output in either model is 300W, 450W peak.

How Long Will It Take to Charge?

The included AC wall charger is 90W, so this will charge in approximately six to seven hours. Also included in the box is a charging cable for use with your car battery from the 12V port.

Solar input is limited to 120W, with an open-circuit voltage of up to 40V. Although an adaptor cable for industry-standard MC4 solar connectors is included, these limitations mean most static panels (such as those taken from a rooftop install) can't be used. Of course, the AC50S is designed to be portable, so this isn't a big deal. For static installations, you should look at the larger Maxoak backup batteries.

Thankfully, Maxoak also sells a portable solar panel perfectly matched to the input rating of the AC50S. We reviewed the SP120 a few months back. Under ideal conditions, the SP120 could charge the AC50S in as little as four to five hours, faster than the AC adaptor. Realistically, it would likely take six hours to a day, given varied cloud cover, the angle of the sun, and other factors.

You can charge and discharge the Bluetti AC50S simultaneously without issue.

Is 300W Continuous and 450W Peak Enough for You?

300W is plenty enough to power laptops, smartphones, tablets, and other USB devices—all at the same time. If that's your intended use case, you needn't worry about the peak rating.

But if you plan to use the AC sockets, you should take note of it. Most small appliances will comfortably run on less than 300W continuous. Still, some such as air conditioners or fridges will surge to five or seven times their rating momentarily when switched on. If they exceed 450W, the Bluetti AC50S will display error 27 and require a restart. Therefore, you must know the peak or surge rating for any appliances you hope to power with the AC50S.

In some cases, there may be a workaround, so you can still use the appliance. For instance, set your coolbox or mini-fridge at room temperature first when switching it on, then slowly decrease the temperature. If your appliance surges beyond 300W but less than 450W, this should be fine as long as it doesn't continue for more than 120 seconds.

How Long Will The AC50S Battery Power Last?

To work out how many hours the AC50S will last you, divide the capacity (500Wh) by the power you're expecting to draw. For example, a 50W CPAP machine could run for around 10 hours. If you're unsure, plug in the device: the helpful indicator on the front of the AC50S will tell you exactly how much power it's using, from which you can calculate. Bear in mind this value may fluctuate. For instance, when I tested a deep freezer, it varied anywhere from 5W to 110W.

For devices like a smartphone, it's more helpful to think about how many charges you'll get from the AC50S. An iPhone 12 could be charged anywhere from 20 to 40 times; a typical laptop will get at least seven charges.

Do You Actually Need "Regulated" 12V?

If you're shopping for backup batteries based purely on color, or if you don't care about the 12V car port output being regulated, then I've got good news: the previous AC50 model comes in orange or grey, and is available for as little as $350 (use the coupon code MAXOAK100 to get that extra $12 off). The only difference (other than color) is that the 12V output is not "regulated." That means you might not quite get 12V. You might get 11V or 11.5V. For some appliances, getting at least 12V minimum is critical, and without that, they won't power on. For others, it won't matter. And if you're not going to use the 12V at all, it obviously doesn't matter.

Portable, Powerful, Perfect for Camping

The Bluetti AC50S is easy to operate, packs a huge amount of power into a small package, and includes lifesaving features like an emergency light and wireless Qi charging–all at a budget-friendly price of under $500. There's a lot to like about the AC50S, and if we had a single complaint, it would be that the AC converter is slightly limited at 300W continuous, with 450W peak meaning some appliances won't work.

Still not convinced? We've secured some special coupons to help you decide:

Behold: A color-changing smart bulb that isn't stupidly expensive

I’ve long held that connected lighting is one of the most sensible smart home upgrades you can invest in — in part, because it really doesn’t need to be much of an investment. Perfectly decent smart bulbs can be had for less than the price of a pizza, and once you buy in, you’ll use them each and every day, complete with the convenience and comfort of automated lighting that you can control with your voice.

Terrific value

Supports voice control via Alexa, Siri and Google Assistant

Fully featured app

Bright, good-looking white light tones, mostly accurate color quality

Additional bulb shapes coming soon

Don’t Like

Many color presets don’t play well with Alexa or Google

Not compatible with Philips Hue’s apps or integrations

Can’t trigger animated presets with voice

No Apple HomeKit support

There’s an exception though, or an asterisk perhaps, and that’s smart bulbs that can change colors. Even as the price of LED lights fell steadily over the past five years or so, color-changing bulbs from well-established names like Philips Hue and Lifx continued to sell at a steep premium. Even if you caught a good sale, you’d be lucky in most cases to get one for anything less than $30.

Things seem to be turning a corner in 2020, though — most notably with the Philips Wiz Connected Smart Wi-Fi LED. Available at Home Depot for just $13 each, it’s a full-fledged color-changer that needs no hub, and it supports voice control via Alexa, Google Assistant or Siri Shortcuts. Its colors aren’t quite as bright or vivid as you’ll get from our top performer in the color-changing category, the Lifx Mini LED, but they still do an admirable job at splashing accurate, eye-catching shades across your walls. Despite the fact that it doesn’t work with the Philips Hue app or with Hue’s immense list of third-party integrations, the bulb still finds plenty to offer via the surprisingly well-featured Wiz app. 

All of that makes these bulbs a terrific and worthy value pick if you’re interested in changing up the colors in your home — and newly announced bulb shapes like a candelabra bulb and an outdoor-rated PAR38 bulb make it easy to expand your setup to include any fixture you like. If you’re interested in deeper integrations with third-party products and services, or advanced features that can sync your lights with your TV or with your music, then you’ll still need to spend up on something from Philips Hue, Lifx or Nanoleaf — but for simple, voice-activated, color-changing light that you can control and program from your phone, these Wiz Connected bulbs will do the trick for a fraction of the cost.

Light bulb basics

For the most part, the Philips Wiz Connected LED works like any other light bulb — just screw it in and turn it on when you want light. The default setting puts out a claimed 800 lumens of brightness at a yellowy color temperature of 2,700 K. That’s the same as you’ll get from a standard 60-watt incandescent light bulb, but since this is an LED we’re talking about, the power draw is much less — just 8.5 watts. 

Those energy savings are worth noting. If you turned the Philips Wiz Connected LED on at full brightness and left it on for an entire year, it’d only add a little over $8 to your energy bill. For comparison, that old-fashioned, 60-watt incandescent would add almost $60 to your bill over the same stretch. Replace a bulb like that with the Philips Wiz Connected LED, then use it for an average of three hours per day — it’ll pay for itself in energy savings in about two years, then keep on shining for another 20 years.

The Philips Wiz Connected LED (center) is about as bright as a Lifx Mini White or Philips Hue LED at its default, soft white setting — but its colors aren’t as bright as those competitors. 

Ry Crist/CNET

As for the brightness, I’m still working from home without access to my lighting lab, so I can’t double-check the specific lumen count just yet. Still, in comparison with other bulbs I’ve tested in the past, including the Philips Hue White LED, it’s easy to see that the Philips Wiz Connected LED does just fine at default settings. That’s much better than the original Wiz LED, which was released before 2019, when the Hong Kong-based startup was purchased by Signify (formerly known as Philips Lighting). That bulb was too dim at its default setting, and only hit peak brightness at an awkward white light color temperature of 4,200 K.

The colors are much less bright than the white light settings, which is to be expected. What’s important is that they’re bright enough to make an impact, and for the most part, accurate in tone — though, it struggles to put out bold shades of yellow or orange. In some cases, the presets used by Alexa and Google aren’t the greatest, either. Ask either assistant for pink, for instance, and you’ll get milky white light.

Color quality is mostly accurate, but the bulb’s palette has a few weak spots.

Ry Crist/CNET

Ugly-looking pinks aside, stalwarts like red, blue and green come through just fine — and if you open the Wiz app, you’ll find a color selector with dozens of different settings, including oddball Crayola rejects like “Razzmatazz,” “Free Speech Green” and “Gorse.” What’s extra odd is that Alexa and Google seem to recognize some of these settings (including a great-looking “Deep Pink”), but not all of them. Google Assistant seemed to recognize more of them, at least, sort of. When I asked it to jump to the “Macaroni and Cheese” setting, it triggered that ugly, milky white again — but that’s better than I got from Alexa, which just looked at me funny before adding mac and cheese to my grocery list.

The app also features a number of “dynamic” color settings that cycle through various shades. Some, like “Ocean” or “Forest,” follow a theme, while others just dance between random colors for romantic mood lighting, party-appropriate dance floor lights, or a simulated candle-like flicker. My big quibble here? There’s no way to activate these with your voice or via any third-party integration. You either have to turn them on in the app, or buy a physical Wiz remote and assign them to its customizable preset buttons.

The Wiz app lets you choose between a long list of simple and dynamic color presets, as well as timed fades and a full color selector.

An app that’s filled with tricks

With a clean interface and plenty of guidance, the Wiz app is simple enough to use — but what’s striking about it is the number of features it boasts, some of which you won’t even find in the Philips Hue or Lifx apps.

You’ll start by turning your bulb on and beginning the pairing process, which requires you to connect to the bulb’s Wi-Fi network so the app can add it onto your home network. It’s especially simple because the bulb uses its color capabilities to signal you along the way. For instance, when you set the bulb to pairing mode, it’ll start pulsing purple once its Wi-Fi network is ready for you to connect.

With the bulb up and running, you’ll specify the room it’s in and give it a name. From there, you’ll be able to turn it on and off and dim it up and own from the home screen. To change the color, tap whatever color is listed as “now playing” to pull up a full list of preset options, as well as the color selector where those oddly named shades are located. I just wish Wiz would relocate this color selector to the home screen so you don’t need an extra tap and scroll in order to pull it up.

Tapping the little gear icon pulls up the system settings, as well as the specific light settings for all of your bulbs. There are tons of neat features tucked away here, including an option to customize how long it takes for the light to fade between changes, and also an energy use tracker. You won’t get either of those with the Philips Hue app.

The Wiz app features a bounty of interesting features, including scenes, schedules, energy monitoring, automated vacation lighting, custom fade durations and a “Rhythm Mode” that lets you plot out a day’s worth of repeatable lighting changes.

Other features include the usual options for saving scenes and for scheduling lighting changes, as well as a “Rhythm Mode” that lets you set the lights to automatically cycle between up to five custom settings at different times of the day. The app starts you off with a circadian mode that automatically adjusts the lights between energizing cool white tones when you wake up and relaxing soft white tones in the evening, with a night light for when you’re asleep. If you’d rather build your own Rhythm that automatically triggers Party Mode whenever your work-from-home day is over, hey, more power to you.

What’s especially nice about the feature is the way Wiz visualizes it with a ring-shaped timeline. Once you plot a lighting change on it — say, lights on at 7 a.m. — it’s a cinch to slide that marker around the ring to make fine adjustments to the schedule. It’s similar to the Lifx app’s Day & Dusk feature, which plots lighting changes along a line graph. I like the Wiz approach even better.

The Wiz app makes it easy to connect with third-party platforms like Alexa.

Screenshots by Ry Crist/CNET

As for integrations, the Wiz app supports Alexa, Google Assistant, IFTTT and a handful of other, smaller smart home platforms. The app does a great job of making it easy to connect with them — for instance, when you tap the option for adding Alexa, it’ll switch apps and send you directly to the authentication page in the Alexa app.

The big, missing integration is Apple HomeKit, but you can still use Siri to control these bulbs if you’re willing to use Apple’s Shortcuts app, which lets you trigger your apps with custom Siri commands. It’s a more limited experience than you get with HomeKit, which lets you program and control devices from various brands in Apple’s Home app, but it does the job. For example, I created a shortcut that turns any Wiz lights in my bedroom on just by saying, “Hey Siri, cue the lights.” That’s probably not enough for anyone who’s already seriously invested in Apple HomeKit, but it’s enough for the bulb to say that it supports voice controls by all three of the major voice assistants, so I’ll give it a passing grade.

I also appreciated the Wiz Connected privacy policy, which does a better job than most of explaining the company’s data practices in plain English. Per that policy, the only info Wiz collects when you use its bulbs are unique product identifiers and diagnostic information, as well as things like a Home ID and specific user preferences from using the app. Wiz also says that it does not share user data with any third parties for the purposes of targeted advertising.

Ry Crist/CNET

The verdict

Color-changing smart bulbs are futuristic and flashy, and they make the smart home fun. That’s why they’ve always been so much more expensive than white light smart bulbs — not because RGB diodes cost a fortune, but because they can have a dramatic impact on the way your home looks and feels. For years, manufacturers have translated that into markup, positioning full-color smart lighting as a luxury.

That’s all well and good for manufacturers, but look back through the last five years of smart home coverage on our site and on others, and count how many times we’ve used pictures of bedrooms and living rooms lit with fancy colors to connote the connected living space. It’s an easy visual for the fun futurism of the smart home, and it’s become one of the first things people imagine when they envision the category as a whole. In other words, these things shouldn’t be seen as a luxury any longer. For many, they’re a staple of the smart home experience.

The Philips Wiz Connected Smart Wi-Fi LED reflects that reality better than any other color-changing smart bulb I’ve tested to date. At $13 each, it’s as affordable as the smart home gets, and with no need for a hub, you can connect it with Alexa, Google or Siri as soon as you screw the thing in. That makes it an excellent pick for beginners, and also a great choice for anyone who’s already invested in a voice-controlled smart home, and who would enjoy expanding the setup to include a fresh pop of color or two.

How To Grow The Biggest Marijuana Buds

After your first successful grow, the next logical question is how can I produce a higher yield next time? The female cannabis plant produces large amounts of THC (tetrahydrocannabinol), and the largest concentration of THC is found in the flowers (buds). You may have seen pictures on social media of enormous buds. It's a sight to behold. How did they do it? With a few tweaks, and some basic knowledge your next grow will reward you with a massive yield. In this article we'll look at several ways to produce big, beautiful, marijuana buds with the highest yield possible. Genetics The single most important factor in producing the largest buds, and yield is to choose the right genetics. Several strains have been genetically engineered to produce the largest, and most potent yields. We see new strains appearing every year, produced by some of the top cannabis breeders. Some strains haven't been modified, and are organically predisposed to produce higher yields. When shopping at an online seed-bank such as Seedsman, you'll see yield quantities listed as part of the description. A yield of 500 grams or higher is considered a high yielding cannabis plant. High yielding plants by default have larger terminal buds. Some high yielding, high THC cannabis plants include Pineapple Express and Grapefruit. Indoor grows will have lower yields than outdoor grows. The roots are confined in pots when growing indoors, so the overall plant size, and yield will be smaller. This shouldn't discourage you from growing indoors.

Nutrition Growing large, healthy buds requires a healthy diet. They require the right nutrients, which vary at different stages of growth. Lets assume for the time being that you're using potting soil as a grow medium, as opposed to hydroponics. While there are some benefits for using hydroponics, such as potency, and shorter time to harvest, bud size and overall yield are best achieved using soil. Like all plants, cannabis requires fertilizer which includes nitrogen (N), phosphorus (P), and potassium (K) (NPK). They also require trace minerals including calcium, magnesium, iron, zinc, sulfur, and boron. Most commercial potting soil (bags) contain the right combination of fertilizer, nutrients and some organic matter required in the early stages of vegetative growth. This may be sufficient for the first few weeks of growth. The vegetative (growth) stage which can last for 7-8 weeks, requires a different combination of nutrients and fertilizer than the flowering stage. The vegetative stage uses more nitrogen (N), and the flowering (bud) stage uses more phosphorus (P). Commercial nutrients contain ratios of 2-2-4 for vegetation (grow), and 0-6-6 (NPK) for flowering. These quantities, and ratios differ slightly by product. There are several commercial nutrient brands available online that provide different combinations, trace minerals and organic matter for each stage of growth. I suggest adding half the recommended dose when starting a nutrient program. Keep a close eye on your plants, checking for drooping or yellowing leaves. Over fertilizing can destroy your plants, so start slowly. Nutrients are added to water, and used once per week. You should stop adding nutrients 1-2 weeks before the harvest, which is referred to a flushing. Only pure water is used at this late stage. Check the pH of the soil, and water. Cannabis plants require a soil pH of between 6.0–6.5. You can adjust pH levels by using products such as pH UP, and pH DOWN. One of the most overlooked nutrients for flowering is CO2. Carbon dioxide is the most essential element for photosynthesis other than direct sunlight (or LED & HID lights). Adding CO2 to the grow during the flowering stage will greatly enhance the size and quality of your buds. If using a grow tent, or closed grow area a cheap and effective way to add CO2 is using dry ice. Dry ice is simply pure, frozen CO2. You can mount the dry ice above each plant and watch it slowly release CO2 gas as it melts. Once per week is sufficient. Another way to get CO2 is renting a refillable CO2 tank. You can also purchase a CO2 machine, which is more costly. Technically water is a nutrient. Make sure you don't over-water. Feel the soil and determine if its dry, moist or wet. You can also purchase a cheap hydrometer, and probe the soil. amzn_assoc_placement = "adunit0"; amzn_assoc_search_bar = "false"; amzn_assoc_tracking_id = "202008f7-20"; amzn_assoc_ad_mode = "manual"; amzn_assoc_ad_type = "smart"; amzn_assoc_marketplace = "amazon"; amzn_assoc_region = "US"; amzn_assoc_title = "Top Nutrient Picks"; amzn_assoc_linkid = "e0bb21f4b7a141b53f8e697000ff98ef"; amzn_assoc_asins = "B0002E5O6O,B0002E5O7S,B00572026S,B004FYSDFQ"; Topping & Trimming All flowers produce the best and biggest fruits at the top of the plant. Its genetically advantageous for the survival of the plant's species. The highest concentration of growth hormone is located at the top of the plant. When left alone to grow, cannabis plants will produce one large terminal bud at the top, and several smaller buds lower down on the plant, known as popcorn buds. When you top the plant, you create a bushier, more dense plant. Topping is essential if you want to significantly increase the yield. The plant will grow out evenly into 4 or more terminal buds over the following days and weeks. Topping should be done at the first 3-4 weeks, when the plant is 6-8 inches in height. There should be at least 4 or 5 nodes, with stems and leaves growing out. Cut off the top leaf including its stem down to the top node. Over the next few weeks you'll see new stems and leaves growing out. These will eventually turn into terminal buds. The plant will become more dense and bushier as it matures. This in turn will produce a much higher yield. Trimming Stated previously, if you left the cannabis plant to grow on its own you'll end up with several small, wispy "popcorn" buds growing on the lower part of the plant. They don't get enough light and resources to grow into full sized buds. Because the lower leaves and stems will not produce quality buds, they're pretty much useless. Trimming, or pruning the lower one third of the plant allows the plant's resources to be dedicated to the larger stems, leaves, and buds towards the top. This step will also increase yield. Start trimming the lower part of the plant at 6-8 weeks, toward the end of the vegetative stage. You can start slowly, and re-visit up to the flowering stage as needed. Don't overdo it, or the plant can go into shock. Lighting Providing adequate lighting is essential for proper growth, in the early stages through flowering. A lack of sufficient light in the first few weeks of growth will lead to a weak, sick plants and disappointment down the road. When using fluorescent or LED lighting in the vegetative stage, make sure the lights are no more than 2 inches above the plant. These lights run cool and won't burn the plant. If the lights are set too high, the plant stretches higher, getting closer to the light to meet its lighting requirements. Stretching leads to weak stems, roots and the plant will not be strong enough to flower. If your using HID lighting such as metal halide in the vegetative stage, you'll need to mount these 24-36 inches higher, as they give off a lot of heat, and have a much higher intensity or lumen output. Metal halide lamps are generally used in commercial grows. Its also important to adjust lighting during the flowering stage. To avoid burning the plants when using high pressure sodium lamps (HPS), the height should be raised enough to avoid burning the plants. Depending on the power, HPS lamps can be mounted as high as 36 inches above the plants. The reflectors spread light evenly, and the intensity gets light down to the bottom of the plants. Over lighting can be as bad as under lighting. Commercial growers tend to use 600 watt HPS, while a small grow of 6 plants or less will get away with a 400, or 250 watt lamp. Many small time, personal growers choose LED lighting for 6 plants or less. LED lights run cool, are energy efficient, and fairly inexpensive. LED technology has improved enough to produce large, healthy flowers. When using LED lights make sure enough light is getting to the lower part of the plant. LED lights should be mounted lower than HPS lighting, yet high enough for the reflector to spread out the light, covering all the plants. You might need 2 or more LED lights for enough coverage, depending on how many plants you're growing. Conclusion Growing large, healthy buds is very achievable if you obtain the right genetics, provide the right nutrients, topping and trimming, and adequate lighting. It seems like a big outlay of cash, but what you purchase upfront will be used for several grows, such as nutrients, lighting, tools etc... Your increased knowledge will lead to a better, more rewarding experience. Also See: Growing Marijuana Indoors For Beginners Read the full article

Aluminum housing IP65 waterproof outdoor low price best quality 420w 350w 300w 250w 200w 150 watt led street light

Most 150 watt led street lights have a lens on the LED panel, which is designed to cast its light in a rectangular pattern, an advantage compared to traditional street lights, which typically have a reflector on the back side of a high-pressure sodium lamp. In this case, much of the luminance of the light is lost and produces light pollution in the air and surrounding environment. As LED lighting fixtures normally produce less illumination[5] it is important to use a well-distributed illumination pattern in order to produce the same illumination as higher-lumen conventional fixtures. For example, different LEDs in one fixture can target different points on the street.

150 watt led street light  SL11 description

1、Unique patented IP65 light Modules 2、 Ergonomic and dedicated lighting distributions available for various roadway applications. 3、 Whole structure heating dissipation design with excellent thermal conduction, radiation and convection. 4、 Flexible to reach desired power selections by choosing appropriate light engines. 5、 Tool-free on site replacements of light modules greatly reduce maintenance cost. 6、Excellent light performance, driver stability and desirable lifespan.

Advantages of 150 watt led street light

Low energy consumption: Many LED lighting retrofits have been claimed to dramatically reduce energy use. Long and predictable lifetime: The projected lifetime of LED street lights is usually 10 to 15 years, two to four times the life of currently prevalent HPS. (LEDs themselves do not generally fail or "burn out" in a way comparable to other technologies, and barring catastrophic failure of other mechanical or electronic components of the LED fixture, lifetimes are typically set by a decrease in luminous output of 30%. But the functional lifetime of an LED fixture is limited by the weakest link; associated drive electronics are typically projected to last about 50,000 hrs. It is important to understand that no LED streetlighting products have been in service long enough to confirm the projections.) If realized in practice, the less frequent need to service or replace LEDs will mean lower maintenance cost.

Your primary reason will help you figure out the answers to other questions, like what type of bulb to get. For security, you might want a motion floodlight that’s meant to surprise an intruder and scare them off. On the other hand, a motion light that makes sure you don’t get tripped up on your way into the house can be less powerful. What Type of Lightbulb Should I Get? Many outdoor lights use LED to help save on electricity and minimize the chance of fire from a traditional, incandescent bulb that gets hot while in use. The downside is that LED lights are often dimmer, which can be a deal breaker if you want to illuminate a big area or startle trespassers. Incandescent light bulbs use more energy and need to be replaced more often, but they tend to be much brighter. Because you’re looking for motion sensor lighting, you should have less worry about incandescent lights heating up from being left on too long. How Much Area Do I Want to Illuminate? The amount of coverage provided by a motion light is determined by the motion sensor range and the brightness of the light bulbs. If you’re looking to light up a small area like the front porch, you may only need a motion sensor with a range of a few feet. But if you want to illuminate a larger area like an entire backyard, you might want a floodlight with a range of 70 feet or more. You can also power up the reach of your motion light with bright bulbs that use more lumens. Small areas can get by with as little as 42 lumens, while floodlights can use up to 3,400. What Type of Power Source Is Best? You can get motion sensor light fixtures that are hardwired, battery powered, or solar powered. The benefit of lights that use battery power or a solar panel is that you don’t have to install them near an electrical outlet. But solar panels need to be affixed where they’ll get enough sunlight for a full charge. The drawbacks with battery and solar power are that your security can be compromised due to a dead battery or a cloudy day. You also sacrifice brightness with those power sources, as the brightest lights tend to use hardwiring. If you do go with hardwired motion lights, be sure to plan ahead in case you need to run wires through walls or secure extension cords.   Can I Add Motion Sensor Lights to My Security System? You should be able to add motion sensor lights to an existing home security system. Contact your security provider to find out if motion sensor lights are available. If the company you use doesn’t offer motion lights, find out if the system is compatible with any third-party motion sensor lights. The benefit of having motion lights integrated into your security system is the convenience of mobile alerts when the lights are activated. Plus, if you have security cameras, the lights can help you get better footage in low-light situations. Check Out More Motion Sensor Options There are many situations where a motion-sensing light can come in handy, whether it’s as a nightlight or a convenient way to see what’s in the back of the closet. These gadgets let you decide where and how you want motion-activated light—both outdoors and inside your home.

No doubt sunlight is your best source for necessary Range that is light to grow crops. However, if there's absolutely no scope to find sunlight you can use a natural light source. I will suggest using a full spectrum LED plant mild easy to use, small in size and longer lifespan.

HPS stands for High-Pressure Sodium and it is a Different type of grow light that's also remarkably popular. LED and HPS have operated and different characteristics in ways that are different. However, the LED plant grow lights are better for many reasons, but I believe this one is the main:

A temperature that is high is reached by HPS lights. That makes you want another ventilation system to prevent your plants getting burnt. LED grow lights are just warm to the touch and you can almost place your plants straight touching without any burn risk.

This reason, among others, makes LEDs a better option for the plants and for your wallet. HPS grow lights need ventilation. Additionally, you need to put them correctly to correctly avoid burns on your plants.

Camping is one of the best ways to get away from the stress of daily life. At your campsite, you and your family can sleep and dine outdoors in a natural and refreshing environment. Whether you are planning to go on your first camping trip or you want to return to camping after a long break, the following tips and ideas will help you to have a great time.

1. Plan Your Activities in Advance

Create a list of camping activities for you and your children. This will help you avoid boredom and prevent the children from getting involved in dangerous stunts. A little brainstorming will help you to generate enough ideas to last for 1 to 3 days. Take a football, kite, board games, fishing gear, a compass and maps for learning and paint and craft items. Incorporate the “location” into the activities. Finds and paint pine cones if available to be a part of an upcoming holiday, bring a book on plants and have a scavenger hunt for the “safe” ones. Be creative in your teaching.

As such you can convert each camping trip to an educational excursion and adventure for your children. Take nature books along and allow the children to have a firsthand experience with the wonders of nature. Schedule photo sessions for both sunrise and sunset and take advantage of these times to capture unique photographs. Add more physical activities like hiking or kayaking if your campsite is near a river or lake.

2. Choose Your Camping Site With Care

The campsite you pick will determine how well you’ll enjoy your trip. Carefully plan how far you want to travel, the type of location (whether you want a coastal area or countryside forest). Decide whether you want to stay in a camp with a lot of facilities or a place in the wild.

   Note that camps with plenty of amenities attract a lot of people and are very noisy while areas that are laid back and pristine usually lack basic facilities. Make sure you choose a campsite that is relatively safe so you don’t have to worry about fending off wild bears when you are meant to be sleeping. 3. Create a Camp Box

Creating a camp box can reduce the time you spend packing for your camping trip by half. Start by making a checklist of items you should take for a typical weekend camping trip. Your checklist should include the following: * Campsite Gear: sleeping bag and pad for each camper, pillows and blankets, heavy duty steel tent stakes and poles, ground cover, extra canopy or tarp, repair kit, chairs, headlamps and lanterns. * Kitchen Utensils: stove and fuel, lighter, firewood, pot and frying pan, portable coffee maker, trash bags, cooler, ice, water bottles, paper towel, bowls,plates, forks, spoons, and knives. * Personal Items: toothbrush, toothpaste, toiletries, soap, sunscreen, first aid kit, insect repellent, and any prescription medication.

Update your “Camp Box” as a family exercise after the trip. Have everyone offer suggestions/improvements and most important, what could have been left out.

4. Get Your Camping Gear Off-season

After you have written out the items for your typical camping trip, you need to go shopping to pick up those you don’t have at home. If you are planning for your first camping trip, you should avoid buying so many items during the peak season for hot weather tent camping.

Although June may seem like a nice time to go shopping for camp gear because of the variety of camping gear that will be on display, don’t do it. At this time, tents and other camping gear will be sold at peak prices. Instead, you should buy camping gear in early spring or winter. Many retailers also try to sell off their camp gear at the end of the summer, so you could get very good bargains at that time.

5. Prepare for Night Lighting

A campsite will feel lonely when walk around with light that is coming from your LED headlamp alone. You should have at least one or two extra lighting sources. These will make your campsite and tent look and feel safer and more exciting.

You may use a powerful rechargeable LED lantern that has about 200 to 250 lumens of light at night or a lantern powered by alkaline batteries. You may also use solar lamps that will be fully charged during the day and provide light for at least 12 hours at night.

6. Go Unplugged and Leave Some Gadgets at Home

Try going for a weekend without your smartphone, tablet or laptop. You will experience a refreshing sense of freedom that will linger for a long time. Going unplugged allows you to rely on your memory and improve your cognate ability instead of depending on Google for every single fact during a discussion with your friends and family. If you feel you will need your smartphone to take pictures, use a digital camera instead. Going without all the digital distractions will revive and rejuvenate your mind. Your attention span will improve and your mood will be transformed.

7. Be Creative With Meals

Plan your meals in advance. Make a list of your meals for each day (breakfast, lunch, dinner and two snacks between meals). Then choose simple recipes that you can easily use to cook at your campsite while focusing on meals that you can cook well over an open flame. You can even practice cooking breakfast meals like cinnamon roll-ups in your yard at home.

Before you set out, prepare some of the food at home. It will be easier to cut vegetables, marinate the meat and wrap potatoes in foil before going to your camp. Pack these into your cooler and set out the food meal by meal. Remember to take all the condiments and utensils you will need to serve each meal.

8. Leave No Trace

Make it your responsibility to practice the principles of “leave no trace” any time you go camping. These principles have been set out to keep campsites tidy. So you can return back month after month, year after year and still have a clean, safe and hygienic place to set up your tent. With the ever increasing number of people going for camping each year, we need to take care of our trash and avoid leaving our poop buried in shallow pits. It is important to stick to trails when moving around and avoid putting soap, food or human waste in streams and lakes.

Conclusion Apply these simple tips before and during your camping trip. Remember to maintain a positive attitude and make the best of your trip even if you experience unexpected changes in weather at your campsite.

Whenever you go out camping, caving or night walking in the great outdoors, chances are you’ll have a headlamp with you.You don’t want to walk into the dunny hole, stroll off a cliff (I’ve done it), or get attacked by “drop bears”! However, have you got the right light for the activity you’re doing? What sort of light is right at night?

Headlamps can be a very confusing product, with lots of different application, ratings, and functions. Having the right one can make life a whole lot easier at night. This article will assess the suitability of headlamps for different activities, explain what the various numbers on a headlamp mean, and suggest some features to look for when buying a new headlamp.

Where you use it

Generally, head torches/headlamps are used for travelling at night, seeing around a campsite, or caving.

Headlamp for travelling at night

For travelling at night, it is important to look for a headlamp with a variety of features. You don’t just want a torch with a hugely powerful spotlight.

A powerful spotlight will give the illumination necessary for seeing things around you, whether this is controls, trail markers or animals, but may interfere with your night vision.

You will need a lower power setting for reading maps, or when you get close to any reflective surfaces. It is also useful to have a wider angle flood setting, so you can see the area around you, not just a small area ahead. Generally look for something with a variety of focuses, and power levels, or separate power settings.

A headlamp for use around the campsite

For use around campsites, a basic headlamp is all that is required. A powerful spotlight is generally overkill, as it will just reflect off something and blind you, or accidentally end up being shone in someone else’s eyes.

Multiple power settings can still be useful as you may want more light for detailed work, such as lighting a fire, or fixing a car, but won’t need all this light to read a book, or drinking a coffee.

Look for something with multiple power levels, remembering it doesn’t need to be hugely powerful or have multiple focuses.

Choosing a headlamp for caving

Caving is similar to travelling at night, however a long battery life, and durability is even more important.

Although there is no natural light at all when you are deep in a cave, it is still useful to have a lower power setting for when you are around other people or doing detailed work yourself.

A powerful spotlight is great for looking around large cavities, and a wide-angle flood light is vital for seeing where you are putting your feet, hands and head. Generally look for a torch with a powerful spot and flood light that has a long battery life.

There are different features to consider for night use. 

What do all these numbers mean?

Headlamps are very technical pieces of equipment, with a variety of specifications, such as brightness, range and battery life.

Brightness

Brightness is generally measured in either lumen (metric) or candela (imperial). One Candela is the light output of an average candle and is equivalent to 12.57 lumen.

Headlamps generally vary in brightness from between about 12 lumens, to 200 lumens, with some specialist models outputting over 500 lumens (but you pay for it).

Naturally the brighter the light, the better you can see around you at night, but don’t make the mistake of just buying the brightest lamp you can find if you don’t need it.

Firstly you will spend a heck of a lot of money, and secondly, chances are it will be so bright it will reflect back into your own eyes, meaning at close range you won’t be able to see anything anyway.

The range of the headlamp

The range of a headlamp relates to both the brightness and the lens quality.The brighter the light, the further it will penetrate, and the more you will be able to see at that distance.

The lens stops the light from spreading out, a LED will radiate light off equally in all directions, and the lens focuses this light into a narrow beam. The better it is focused, the further it will travel before dissipating.

Be careful because the range the manufacturer’s quotes is often ambitious, and could only be achieved using very good batteries, at full power in total darkness, and even then the detail at that distance may not be all that good.

I’ve generally found that you have good lighting to about half the range the manufacturer recommends, but this varies over the battery life.

Battery life of headlamps

Naturally the longer the battery life, the less often you need to replace the batteries. The problem is that LED lights continue to get progressively dimmer from the moment they are turned on. The battery life, quoted on a headlamp, is the headlamps life until it reaches about 1 lumen of brightness.

The useable battery life is often significantly less that the advertised life. There is a feature called constant current which will be discussed below, which helps improve the useable battery life, but the best solution isto always have spare batteries.

Why do I want all these features?

Headlamps come with a variety of features including different powered lights, different coloured lights, different lighting modes, and features to improve the battery life.

Most mid to high-end headlamps come with either a power adjustable main light or secondary light sources of lower power. These lower settings cannot only be invaluable for seeing things that are close to you, but they also use far less battery power than the primary light.

These settings are a better alternative for just being seen, or when you don’t require great detail at a distance.

Coloured Lights

Many headlamps have different coloured lights, each with a specific purpose. The most common is a red light.

Red lights are used for low powered lighting, which won’t destroy your night vision.This makes it great for using when you don’t want to wake up someone you are sharing a tent with. Or if need a little bit of light to do detailed work such tying your shoelace, but don’t want to lose your night vision.

Green lights are wonderful for reading maps, they highlight contours far beyond normal vision and improve the visibility of detail. Greenlight also has less effect on your night vision than white light.

Blue and ultraviolet lights are used for tracking and highlight blood. Blue lights specifically can make maps easier to read, and are the only lights that will cut through the fog.

Coloured lights are very useful for different purposes, especially when the lights are being used in high-performance applications.

Lighting Modes

Some headlamps have a series of lighting modes, such as flashing, flood or spot. Flashing lights are useful for being seen, such as when running or riding at night, but don’t provide good vision for the user.

Flood or wide angle lighting is good for seeing your immediate surroundings. This is good for camping or walking at night, where seeing the area around you in detail is more important than seeing objects at a distance.

Spotlights are primarily useful for seeing objects at a distance when riding or walking. They can also provide a lot of light over a small area at close range.

A variety of different functions, especially flood and spot functions, can vastly improve the versatility of a headlamp.

Lighting modes improve the versatility of the unit. 

Constant Current

A nifty feature called constant current can improve the performance of LED lights significantly.

This feature maintains a constant current throughout the battery life. This means the light will remain at a constant brightness for the entire battery life. The current then drops off quickly when the battery is about to die.

The only disadvantage is that you don’t know how much power is left in your batteries. So they can run out very quickly, at very inconvenient times so always carry spare batteries.

If you weren’t aware before, I’m sure you now understand that headlamps are more than just a beam of light. Doing your research is important and it may even be necessary at times to have multiple torches to fit different applications. Having the right light at night can make a world of difference and vastly improve your next trip.

Headlamp Black Diamond Storm $50, 3.9 oz. (with 4 AAA batteries, included) moosejaw.com

As darkness and light rain both fell on a partner and I for the last couple of miles of a 27-mile dayhike the length of western Maine’s brutally rugged Mahoosuc Range, I slipped the Storm onto my head—which helped prevent my shuffling and occasional staggering from turning into falling. I also used this ultralight headlamp in campsites from Idaho’s City of Rocks National Reserve and Yosemite National Park to backpacking the Grand Canyon’s Thunder River-Deer Creek Loop. Through all that field testing, the Storm proved itself one of the best high-performance headlamps on the market today. Here’s why.

Few backcountry headlamps have the Storm’s range of features and power, and perhaps none do at its price. For starters, it sports 350 lumens of power in its two LED bulbs—a very bright spotlight and an excellent LED proximity beam for illuminating a campsite, tent interior, or a map or book page. That’s brighter than most headlamps in this weight class. Night vision mode offers three colors: the most common, red, plus green (useful for hunters because it doesn’t disturb game animals), and blue (which cuts through fog). The Storm is rated IP67, meaning it’s both dustproof and waterproof to one meter for up to 30 minutes.

As with other BD headlamps, the Storm has a couple of features I use frequently: Power Tap technology, which allows you to switch instantly between a dimmed level (that you set) and full brightness simply by tapping the side of the casing; and Brightness Memory, which lets you power the light on and off at a chosen brightness level without having to go to full power (draining batteries).

While the instructions can appear complicated at first glance, using the Storm is fairly intuitive; and anyone who’s owned a BD headlamp of recent vintage will find it familiar. Depress the power button once for on-off, twice to change modes—for instance, from spotlight to proximity beam in white, or from red to green to blue when in a night mode. Press it three times to enter strobe for whichever mode it’s in. In any mode, hold it down when turned on to dim and brighten. Hold two seconds to change between white and red LED modes, and double-click in red mode to switch to green and blue; all three colors have a strobe option.

  Black Diamond Storm headlamp open.

Like other BD lamps, the Storm locks off by depressing the power button for four seconds (a blue light will blink rapidly for three seconds when it’s locked off)—a very useful feature to prevent accidentally draining your batteries inside your pack.

Operating on four AAA batteries, it has a longer battery life than many ultralight competitors: BD puts it at 40 hours of battery life at high power, and says that’s based on testing battery life down to the threshold of what is considered “usable” light, for which the industry standard (also used by other companies) is 0.25 lux at two meters. At low power, battery life is up to 120 hours, according to BD.

But that leads to a minor drawback of the Storm: Four batteries make it slightly heavier than the lightest headlamps, and it feels a little bulkier on your head. Although it never bobbed, even when hiking fast, runners may find it a little large. A lever lock provides easy access to the battery compartment without requiring a tool. Any rechargeable batteries can be used in the Storm.

  Whether you’re hiking or descending from a climb after dark, route-finding, starting a dawn-patrol ski run long before sunup, firing up a stove, or just kicking around the campsite at night, the Storm is one of the two or three most versatile, high-performance ultralight headlamps on the market.

At just $10 more than the popular Black Diamond Spot, the Storm has more features and brightness, along with slightly more weight. Some users may not need that enhanced performance. But hard-core wilderness backpackers, climbers, hunters, and ultra-hikers will appreciate the brightness boost, watertight housing, and rangy feature set that can handle any adventure—at a competitive price.
