I have a replacement lamp for an infocus projector. I would like to
check it to see if it is good. I used an ohmmeter to check across the
terminals but it registers open. I actually think that this is an a/c
bulb of some sort. I was wondering if I could just put 115v across the
terminals to check it. The bulb looks brand new and is supposed to be
good. I don't know the voltage rating of the bulb, but I'm sure it has
to be A/C. The bulb is 200 watts output. Is it possible for the bulb
to be some kind of funky gas discharge bulb that would show open with
an ohmmeter when the bulb is good?

thanks,
Tracy
