I'm blessed (?) with a projector with a 750 hour lamp life and last night the normal boot up routine was interrupted by a message that the lamp had clocked up its quota of hours and needed to be replaced. The lamp hadn't failed (I couldn't have read the message if that had been the case), but the message included a dire warning about possible damage to the projector if I ignored the warning. Now, given the financial incentive of manufacturers to sell lamps, can I assume they are being over cautious? What do you lot do - run the lamp until it fails to strike, or replace at the allotted interval to be on the safe side? I have the option of resetting the lamp life counter and carrying on with my fingers crossed but obviously I don't want to damage the projector. Does anyone know what kind of damage could be caused by running in excess of rated hours? The projector's a Barco Graphics 6300. Ta.
