IMO, 4500K is a good balance between nice colour and light output. A higher colour temperature means you get more blue, and less of it.

The human eye is less sensitive to the shorter wavelength light (blue) compared with white or yellow light, so in fact you are getting less light and your eye sees it dimmer too. Double whammy there.

I just installed 4000K HIDs and am really happy with them. These might be too white (or even yellowish) for most people though.

This is a common misconception. 6000k, which I am going for, is very good light ouput, same as 4500. The slight, tiny eeny, tiney winey, difference cannot be noticed at all.

Except on passing by drivers flashing their lights

That is not a misconception because the difference is apparent. You get approximately 2800 lumens with 6000K and 3200 lumens with 4100K. The best light output is at 4100K. Anyway, I can tell the difference.

I've done enough of these to know what I'm talking about. This is confirmed by my side-by-side comparison when I swapped out 6000K with 4100K. Photos taken on daylight film with all pics shot at the same exposure.

so 6000k driving lights, 4100k high beams and what for fogs?

[FiveFreshFish]

My recommendation: No 6000K anywhere.

Just use regular halogen bulbs for your high beams because HIDs don't light up fast enough to flash and it's hard on the ballast if you are on the highway flipping them on and off. This is the reason why manufacturers never used HIDs in high beams until bi-xenons were introduced.

You can get 3000K HID fogs. Looks clean because everything is clear until you light 'em up.

Bi Xenons? Retrofit for E32 avalible by any chance?
