White light

There is some informed commentary at the IAF subreddit.


  1. When LED car headlights started being put on cars, I pointed out to friends while driving at night that some headlights were yellow (the older, incandescent ones) others were blueish white (the new LED ones). They could not see the difference.

  2. The move away from the incandescent yellow was long before the LEDs. First "for off road use only", then when the feds allowed other than the old sealed beam lights, there have been white and blue Halogens, and Xenons. With the LEDs coming at them they were lucky to see at all, no less a difference.

  3. I'm way into 3000k+. Warm yellow, soft lights are the best.
