Projector lamp life-span

The expected life of Projector lamps will vary based on the technology; however, most are offer about 2000 hours. It’s success rate is based on a bell curve, so that a majority of (but not all) its will meet life hours specified. Some will fail sooner and this is part of the acceptable operating range of the rating.
Projector lamps that are used more often or are exposed to environmental contaminants are more likely to show a decrease in lamp life. It is operated 24 hours a day, 7 days a week are of course, at the highest likelihood of 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 it to overheat; the number one cause failure is excessive temperature stress.
Allow it to cool for at least 10 minutes after powering down, and never move it during this period. It is much more susceptible to damage while it is hot.
Operate it 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 are fan or exhaust so excess heat can be dispersed properly.
Utilize the “economy mode” if it is available with your model and is appropriate for your situation. This mode decreases it’s brightness but it will last longer.
