My EX1500 projector is sometimes reluctant to strike and takes several attempts, leading me to think the lamp is on the way out. It uses a 300 watt lamp but I have been offered a 350 watt one as used in the Ex2000 as a possible replacement. The dimensions suggest that it would fit physically, but would this be a wise (or safe!) thing to do? Any advise would be appreciated.

I'd only fit the exact specification as the lamp you are replacing. At best, you could burn out the power supply. At worst, the lamp will explode like a small hand grenade. With these lamps, take no risks!

Can't see why it would explode, might be harder to strike. If you don't have to pay a bomb for it (pardon the pun) I would give it a try.

No this is one lamp I would not mess about with. Remember the reflector around the lamp is destroyed when a lamp explodes and these are rarer than hen's teeth! Try and fit the exact lamp. Be very careful and google safety advice before starting the job. Very risky job.

If you are inexperienced with the inner workings of projectors best to use the rated lamp. I have some experience rebuilding and modding 35 and 16 xenons projectors, with precautions and without lamp explosions. Though I have seen the damage done to reflectors after the event while working as a projectionist. I would bench the higher rated lamp to test it before installing it.
If you have no experience repairing or modding, as the guys said above use the right rated lamp. [Smile]

Thanks and a happy new year to everyone who responded with helpful advise. I shall heed the warnings and seek out the correct replacement lamp!
