This seems so odd cuz it's all red. I wanna test out the color temperature theory that goes about there are warm reds and cool reds and that if you can create depth in your drawing by putting that knowledge to use. Of course, it has to be another Crowley merged with Wang Ye style cause I'm still obsessed.

Do you think the new blue/white headlights on cars are a dazzle hazard?

The prevalence of modern blue LED and halogen headlights (typically 4,000-6,500K) creates certain glare hazards, particularly due to their brightness, color spectrum, and design flaws. The following is a detailed analysis of these risks and their causes:

1. Blue-white light and glare mechanisms

Higher color temperature: Modern headlights, such as Philips WhiteVision H4 (4,100-4,200K) and aftermarket LEDs (up to 6,500K), have very little blue light below 6,500K, and increase the amount of blue light output above 6,500K as the color temperature increases, reaching pure blue light at 10,000K. Due to Rayleigh scattering, blue wavelengths (450-495 nm) are scattered more strongly in the human eye, amplifying the perception of glare by 3-5 times compared to higher color temperature halogen bulbs (3,000K).

Retinal effects: Blue light suppresses melatonin secretion and reduces night vision adaptation, especially for older drivers and those with cataracts or astigmatism.

2. Design and regulatory loopholes

LED power is too high: Cheap aftermarket LED kits (such as the 30,000 lumen bulb sold on DHgate) often exceed the brightness limit of road regulations, and the beam is improperly aligned, and LED bulbs that cannot adjust the light pattern cause dangerous scatter.

Height and alignment issues: SUVs and trucks with high-mounted headlights (70-90 cm ground clearance) will shine the beam directly onto the windshield of cars. Studies show that SUVs have 40% more glare complaints than cars.

Loose standards: US regulations (FMVSS 108) allow headlights to have a maximum brightness of 700,000 candela, while the EU limits it to 425,000 candela. Many countries lack strict color temperature restrictions.

3. Safety Risks and Driver Complaints

Accident Statistics: In the UK, 67% of drivers report slowing down due to glare, and 64% believe that overly bright headlights may have caused a collision.

Age-related Vulnerabilities: Drivers over 50 have 50% slower pupil constriction, making them more susceptible to sudden glare.

Confusion with Emergency Vehicles: Blue lights (e.g. 10,000K LEDs) may mimic police/emergency vehicle lights, e.g. Arizona bans blue headlights.

4. Mitigation Measures

Regulatory Updates: The EU will mandate adaptive matrix headlights (automatically adjust the beam) by 2027 to reduce glare. Japan plans to limit headlight color temperature to 5,000K.

Technology Solutions:

Laser-Assisted Beams: Precisely focused beam patterns (e.g. Audi’s laser system) minimize stray glare.

Anti-glare coating: High-end bulbs like Philips WhiteVision use UV-blocking quartz glass to reduce scatter.

Adjustable light pattern LEDs: High-end bulbs like SNGL use LED bulbs that can be adjusted by rotating the chuck to minimize dark areas and glare in the light pattern.

Driver education: Promote proper headlight height calibration checks and avoid non-compliant aftermarket kits.

Conclusion: Clear danger requires action While blue-white headlights can improve driver visibility, poor regulation of their intensity and color spectrum poses measurable risks. Solutions require stricter global standards, smarter adaptive technology, and public awareness. Until then, drivers should prioritize road-legal bulbs (such as 4,100K halogen lamps) and avoid aftermarket LED lamps with color temperatures exceeding 6500k.

For those affected, anti-glare glasses (yellow/amber lenses) or adjusting the rearview mirror to "night mode" can reduce discomfort. Regulators must urgently address this conflict between innovation and safety.

'The Changing Shape of Cinema: The History of Aspect Ratio' "Trace the evolution of the screen shape from the silent film days through the widescreen explosion of the 50s, to the aspect ratio of modern digital cameras." Interesting video I came across yesterday from 11 years ago that does what the above description says. It's worth a watch if you're curious about the subject matter. Additional informative videos: 1.

portrait study…….. I was focusing on appeal, color jitter, color temperature, bounce light (from her earring onto her neck), and consciously thinking about different kinds of edges.

New IPF bulbs for the Euro headlights to replace the PIAA bulbs. We will see how long they last.

Finally found the color yellow I wanted for the running/parking lights and they are high quality t10 LEDs. Currently using the PIAA ion yellow bulbs but they are halogen and don't last long, not even a year.

I was also looking to change to a 45-5000K bulb and these are freaking rad! They have a silicone ring that has a long lasting blue glow after the headlight is turned off and at dusk from the sun.

Was using 2500K solar yellow PIAA bulbs but they just are not bright enough for headlight use but work great for fogs.

For those of you wondering what light color or Kelvin to choose, this is a good reference using natural light. I personally stay away from anything over 5000K because it's too blue and kinda obnoxious. Between 4-5000K for headlights is perfect while 25-3500K is better for low visibility like fog and snow.

my friend & i talk about this all the time. the new LED headlights are actually blinding to me & triggering of migraines. the warm toned older ones weren't broken so why fix them! that and streetlights should have some sort of regulations as to color temps.

I honestly feel like the proliferation of LED headlights was the canary in the coalmine for the general attitude we see in the political climate these days and i'm not even remotely kidding

I tend to prefer 3000-3500 K for living and reading space, and about 4000 K for work areas. My Asian wife likes cooler temperatures in her work areas, up to 5000 K. I have noticed that many Asians in my acquaintance prefer cooler lighting, which seems too garish for me. Is this an ethnic/cultural thing? Mood lighting can go warmer, all the way down to 2200 K, reminiscent of oil lamps and candles. Curiously, I enjoy watching TV in a red-lit room. Like sitting by a fire at night?

There are so many different shades of white light bulbs, I am so overwhelmed walking down the light bulb aisle, and then I'm never happy with the one I choose, no matter which one I choose, I get it home and I put it in and I'm like, ugh, I don't like THAT white
