How long do LCD projector bulbs last?
It varies. I have seen numbers from about 1000 to 5000 hours of operation. The bulbs in projectors typically get dimmer with use, so some will want to replace them before the life expectancy. The projector manufacturers probably give a conservative estimate to make sure the bulb does not fail in the projector or give unacceptable performance, so the bulb MIGHT “last” longer, but I don’t recommend pressing your luck. The same bulb in different projectors may have different life expectancy if the projectors use different lamp voltage or cooling (the way the bulb warms up and cools down can affect its life).
