Hi guys. Have a question in relation to the HP VP6121 which uses an NSH200BQ lamp. I couldn't find an NSH200BQ on the cheap, but I found a bulb from a canon SX50 which is also a 200 watt NSH bulb, but the model is slightly different. The canon is a NSH200PQ (I think I can't find it online and I don't have the bulb with me). Should these be electrically compatible, because the bulb didn't work and I don't want to waste more money on the bulb if something else is broken. Appreciate any help you guys can give me.
