Higher K lights work ok in concrete jungle settings but will remove almost all depth perception in the country. I’ve been working in lighting development including building LED landing lights for planes since 2003 so I have a little bit of experience in the subject. I have a portable xenon search light that is 5500k and can send a spot over half a mile but when you beam it onto a tree even at close range the spot looks almost purely two dimensional.
The factory knows what they are doing you should never go higher than 4300 for high beams but I like 5000 for city driving it pairs better with concrete and I’m a religious user of high beams in the country and the mix of 4300 and 5000 works great. (Depth perception at distance with the 4300 and close up lighting of roadway at 5000)
It’s literally dangerous to use higher K for high beams as you will lose a great deal of depth perception any higher than 4300k. Something clearly important to avoid hazards as well as simply aim for the apex of curves while driving.
Asphalt, stone, shrub, trees, leaves; they are all “tuned” to lower K light. The further you stray from 4000, the less well you can see any of those things.
