My cars HID changed color. its originally 6500K but the right one has changed color, more like 5000K. what is most likely to couse it? power supply(voltage dropy)? ballast damage? or the bulb itself?

thanks

Is it a cheap Asian made conversion kit? 6500K is not OEM color so the bulb is most likely Asian made. All new cars come with 4200K.

Alot of HID bulbs will shift to a slightly lower K temp over time.

Why one is shifting faster than the other, i dont know.

I've always read it the other way around. That they go up in K over time, but with bulbs made overseas it might do all sorts of things. There are a lot of aftermarket companies out now making HID bulbs for cars.

Cheap bulbs change color more easily and if you are close to the end of the bulbs life, it's likley to change color.

if your talking about the change in the tint of light, Doug [Quickbeam]'s made a logical explanation to that. On this review of the 24W HID from PTS
http://www.flashlightreviews.com/reviews/aelight_pl24.htm

Quickbeam said:
I did notice that if you wiggle the light around or point it face down the light changes color. This is due to condensed substances in the bulb entering the path of the arc. Generally when held horizontal the light was a bluish white, but when held vertically face down the light turned slightly orange.

Hope this helps

cheers

Xeray: kinda scary to swap bulb though. i am afraid to damage the left one. if indeed coused by damaged ballast. anyway i might try it.

no it stays with the same green tint. does not change color because of the orientation. But its always like the original) when warmed-up.
