[fxmartin]

hi, i have bougt a benq pe5120 and i would replace the lamp by an BLV topspot 150w on my ballast 200w. So i have try to search but i don't know if my lamp is AC or DC ? Someone does have this information please ? Thanks for all 🙂

Have a look, the DC electrodes are unequal while the AC ones are identical.
There's another thread where they resourced commercial projector lamps very cheap (like 30$) from/through China.

Is your lamp like this?

can you give me a pic like this, you have to pull out your bulb to take pic.

An externally hosted image should be here but it was not working when we last tested it.

and 150w on my ballast 200w is short life, dont do this, 200w to 200w ballast is good.
the VIP and VIP R are AC lamp.
