Projector lamps, projector light bulbs or projector bulbs, are user replaceable
projector parts. There are several different projector lamp technologies of differing
wattages. Be sure your projector light bulb matches the one you are replacing. Consult
your User's Manual for information on replacing the lamp.
Projector lamps dim as they age. Some projectors allow you to check the number of
hours your lamp has been used through the built-in menu. Check your manual.
Just like any light bulb, projector lamps have an expected operating time, called
lamp life. The expected life of a projector lamp will vary based on the lamp technology
and the projector; however, most projectors offer about 2000 hours. The lamp's success
rate is based on a bell curve, so that a majority of (but not all) lamps will meet
the lamp life hours specified. Some lamps will fail sooner and this is part of the
acceptable operating range of the rating.
For projectors that are used under normal operating conditions (no more than three
to five hours per day in a clean, relatively dust-free environment) the lamp will
have the greatest likelihood of lasting through its entire rated lamp life.
To increase lamp life avoid allowing the projector to become overheated. Make sure
there is adequate clearance near the intake and exhaust vents. Operate your projector
in a clean environment. Clean air filters every 3 months or more often if there
is a lot of dust in the room. Avoid shock to the lamp or projector.
Use "Lamp Economy Mode", if available, to lengthen the life of the lamp by reducing
its brightness. In most cases you will get a 50% increase in lamp life with a 20%
reduction in brightness. Allow the projector fan to turn off after you power down
and before you unplug the projector. The only exception to this is a projector that
is designed to keep the fan turning for a brief period after removing power.
