New HID bulb sediment?
I just got my new OEM phillips HID bulbs in the mail and notice that there is some gray sediment in the bulb (as if it looked used).

Do new bulbs have smoky gray sediment on the inside?

That's the Metal Halide salt. It's normal.

if they are brand new, it should be yellowish. the older they get the more grey/darker it gets. dark grey usually means the bulb is dead.
