With your projector, I know the simple solution for emergency bulb cooling is to buy a UPS system. When the power goes out due to a thunderstorm or whatever, you can still have a safe method for cooling your bulb down. But... 1. What would you do if you didn't have an UPS for your projector? Let's say you took your projector to a friend's house and you forgot to bring along your battery backup. A storm rapidly develops and the power goes out. Is it a crazy idea to put the projector in the fridge? Or maybe sit it in front of a window AC unit (if you had one)? I know these are ridiculous ideas, but what could someone do in the case of an emergency? And just as a poll... 2. How many cool-down minutes do you give to your projector? When I first bought my Infocus Screenplay 4800, I used to just wait until the fan speed changed from high to low, then I would flip off the rocker switch (about a 2-minute process). But later on in my first week of owning it, the fan would not run at the regular speed during normal operation. As a result, the projector kept automatically shutting itself off (overheating). My uneducated guess :b was that since I was always too quick to shut the projector off, I could have heat-warped the fan parts or something and the fan couldn't turn at efficient cooling speed. I exchanged it for a new one and ever since have always allowed 30 minutes to cool my lamp before fully switching it off. Is 30 minutes way more than enough?
