not 8000K but 12000K. it doesn't look 12000K tho, need to be 14000K to look like 12000K. My fogs are also 12000K. I'll have pics up tonight.
Now how high does it get anyway?!?
PS: How many K does the stock ones have?

Daylight is 5000K . the higher you go in the Kelvins, the more blue the light gets until it gets purple. The lower you go it turns from white into yellow into red.
Any Xenon headlights more than 6-7K will not give you any improvement in lighting out the road, really.

They don't get better for lighting purposes if you go higher and higher. They rather get less effective in lighting out the road ahead.

Yup. Thats true, until you get 55W ballasts... They're bright, the only thing is, our eyes are so used to normal color that we don't think we see clearly when purple light is shining on something. I hope you understand what I mean. 55W Xenons are super bright, about 60% brighter than the ordinary 35W ones, I quote. Right now, I have 12000K fog and 12000K above, but I'm changing it to 14000K headlight, because the projector lens make the 12000K look like 10000K. The problem now is the ballast of BMW which is only 35W, i'm still wondering if I can change that ballast to the 55W ones. Sorry no pics yet, my camera isn't charged.
Fact - not custom or impression - is that the human eye is most sensitive to colors that are dominant in normal sunlinght i.e. greenish yellow (somewhere between 4 and 6,000 K). Blue may look "cool" (does it? really?), but it's also less safe, unless you increase power correspondingly.

I have heard different numbers mentioned - all between 4300 and 4700K. Which is a pretty good approximation of natural (sun)light in a normal landscape (e.g. no snow all around you), and matches what I would expect. But I don't know the "real" spec...
