The average lifespan of a lamp, perhaps the most important part of
the projector, is between 2,000 and 4,000 hours. As time goes on, the
image will stay nice and bright, but toward the end of its life, it will
start to dim. If you run the projector often and at full power, expect
it to last around 2,000 hours. If you use energy saving modes, it will
last up to 4,000 hours. When a lamp goes out, it can cost around $200 to
$400 to replace.
Some tips to help with lamp life: A little maintenance via filter
cleanings will help extend that life; keep the exhaust fan open and away
from objects that might obstruct it; and take care when turning it off
right after the projector has been turned on – wait at least five
minutes.
