| Re: How to tell if a lamp is bad?
I must have installed at least 25 optoma projectors this year. Most of them are home theater projectors.I had come across some problem in 3 projectors.
What i believe is the projector needs to be properly shut down. In India we face power failures , hence we use "UPS" ( uninterrupted power supply ). The projector lamp needs to cool down and that's why even when you switch off the projector with the remote, the fan keeps running even after switching off for 20-50 sec depending on the room temperature and the lamp heat . When ever you ceiling mount a projector make sure the air-conditioner is not too close. So that you don't cool the lamp and kick it on .
I prefer not to switch on the projector immediately after switching off , cause kicking on the lamp when it is too hot must be avoided.
Facts on lamp life:
Every manufacturer claims 2000/3000 hrs . The exact way to achieve is to avoid too many switch on's. Plan for a movie and switch on . If you are going to switch on and off a minimum 10 times a day ,Your lamp life might not even reach half its life.
