I have heard from many people that 4300k is pure white and the brightest. BTW what color is the strip on the 4300k bulb suppose to be?

Also stealthee has mentioned, before on this thread a page or two back, that 4300k is purest white and birghtest and gives the most usable lumens in the output. Also i do agree when i looked at my fogs lamps they seem to have some yellowish oem style color on it but it was a brighter color than my 6000k headlamps.
