Headlights - a question of colour
« on: 17 July 2011, 18:05:05 »
Apologies for asking something that has already been covered to death, but I know that some of you out there are clued up on headlights, so thought I would ask for help.

I am looking to replace a set of H4 bulbs in one of my cars, and because of the project in mind, looking to keep within the confines of legality, so am sticking with 55/60W bulbs. However, I know that there can be a great variation of colour output depending on the ????K rating and am looking for something that will give me a nice "pure white" output. I don`t want them to go so high that they become "blued" or "purpled" and it must be said that this effect is not necessarily for road use or driving, its a purely "cosmetic" colour that I am trying to get for a car.

Any suggestions on the K rating I should aim for?

Most standard HIDs are around 4500k.  IMHO, once you start to exceed 5000k, you creep into chav territory

I was mindfull of becoming a Chav - however, this is actually for a car we are doing a photo shoot on, and I just needed to get some very "White" lights.

5000 have been fitted and are spot on !

Yes, once above 5K they get rather blue/purple and the useable light output actualy drops off quite a lot.

4-5K gives a more white light which allows more detail to be seen on the road in front.  :y

4.3k is what your looking for, like others have said 6k and above looks off aftermarket / chav territory  ;D ;D

If you read the original question, I am after effect, not for driving on !!

The answer I got of 5000K was absolutely spot on for my requirements -

If I wanted them for driving, then I may possibly have looked at something else
