Xenon Bulb

[chas3]

I ordered a pair of two xenon bulbs, Philips D2S 85122+. They were ordered on ebay and the seller posted them as new, never used. However, I am not sure they actually are brand new, the glass ball in the middle of the bulb is half yellow colored. Could somebody confirm if brand new bulbs should be like that?

The camera didn't exactly pick up the yellow tint I am talking about:





There is a grainy yellow tint on the side of the electrode. Only the small glass ball at the middle of the bulb has it.

I edited one of the photos to highlight the yellow tint area, since the camera didn't quite catch it.

Hi Chas,
I have Osram bulbs and they do have a creamy colour spot in the middle.The Philips,however,seem to have a more yellow colour as you can see here in their wesite pics

So the bulbs you bought off Ebay seem to be new,but try them and see,before you give the Seller ,the feedback

from what ive seen, the actual light given off from replacement xenons tends to be more yellow at first but goes to normal color not too long after

Alright, that photo removed any doubts. My new bulbs have that exact same tint. I installed them and they seem to be working just fine (still daylight here). The headlight case was a PITA to remove, since I did it without removing the front bumper.

Yes, most of the bulbs will output less K for the first hours (Philips claims 100 hours), after which the temperature bump a few K permanently, resulting in a slightly more blueish light. There also are bulbs locked at the final temperature (Philips has the ColorMatch series), that won't change temperature over time, usually designed to allow you to replace a single bulb and have them the same color. Anyway, my doubt were about that tint inside the bulb which is visible with the bulb removed/disconnected, like the pictures Powers posted.

Moving on, I noticed the driver side HID bulb mount (inside the headlight) was a little bit loose. I thought it was because of the adaptive lights, but then I compared it with the passenger side, which felt more solid. Should I worry and try to re-tighten any screws?
The adaptives work just fine, both by themselves and through INPA, no flashing "A" LED on the light knob either.
