metal halide emmission?

You are all correct, the glass envelope around a single-ended bulb is both protection for the tube inside, and a UV shield. Think of it as an HQI or double-ended bulb with the UV shield built in... And on that note DO NOT use the damaged bulb further. You will either fry your retinas or your corals and fish or both.

it is a mogul base
i was thinking if its only damaging to me its ok because its inclosed by the inwall hood.
i suppose i will have to dispose of it for the damage of the tank.
