    Default HID Bulb change color

    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

    So it went from a bluish color to more of a whiteish color? Usually HID bulbs change color over time, but it usually goes up in degrees K not down.

    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.

    Swap bulbs between both sides, see if the problem moves with the bulb.

    Cheap bulbs change color more easily and if you are close to the end of the bulbs life, it's likley to change color.
    Still no response to that PM or e-mail you sent me two months ago? Try sending it again. I'm terrible at keeping track of messages.

    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/rev...light_pl24.htm

    Quote Originally Posted by Quickbeam

    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.
