I know we need to look after our projector lamps, but how far do you go. We were settling down for a movie (the VW11 projector had been on about 5 minutes) when I accidentally pressed the 'power off' button. Being the cautious guy I am, I refused to turn it back on for 30 minutes to prevent heat/power build up which I thought might damage the lamp. Is this unreasonable? I'm sure I read somewhere that this can cause lamp fatality. Everyone thinks I've gone mad. Have I?
