Projector lamp lifespan
The expected life of a 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.
Projectors that are used more often or are exposed to environmental contaminants are more likely to show a decrease in lamp life. Projectors that are operated 24 hours a day, 7 days a week are of course, at the highest likelihood of lamp failure before the end of the rated hours.
The following is a list of preventative measures you can take to reduce the likelihood of your projector lamp failing early:
Do not allow the projector to overheat; the number one cause of lamp failure is excessive temperature stress.
Allow the projector lamp to cool for at least 10 minutes after powering down, and never move the projector during this period or while the lamp is on. The lamp is much more susceptible to damage while it is hot.
Operate your projector in a clean, relatively dust-free environment to prevent clogging of fans and air filters. These filters should be cleaned regularly.
Allow plenty of space around the projector’s fan or exhaust so excess heat can be dispersed properly.
Utilize the “economy mode” if it is available with your projector model and is appropriate for your situation. This mode decreases projector brightness but the lamp will last longer.
