ok, so last episode i bought a new xm bulb for my fixture--and while it fired, the other (old) bulb wouldnt light. so i swapped the bulbs around, and came to the conlusion that all three bulbs (2 old of indeterminate origin and one new xm) all work and for some reason, one of the bulbs wont light anymore.
how do i diagnose this? it tries to fire, the bulb will even get hot, but it wont light...what do i do next?

tim
oh--150W DE bulbs.
