Tips to Extend Projector Lamp Life
Lamp life for a projector will vary based on many factors including application, installation, intake of cool air and exhaust of hot air, usage, and proper maintenance. Heat buildup can reduce lamp life and even damage your projector. Here are some tips to help your projector lamps last longer.
1. Once you turn on your projector, wait at least five minutes before turning it off to allow the fan to properly cool the unit. After the fan has cooled your projector, you may unplug it and store it as desired.
2. Do not obstruct the air intake or exhaust vent. Paper should not be placed on top of a projector, or where vents are located.
3. Keep the exhaust vent at least two feet from any object.
4. If the projector is built into a compartment, wall, ceiling or shelf mount, the minimum distance requirement (usually at least two feet) stated in your owners manual must be maintained.
5. Clean the projector's air intake filter every three to six months -- or more frequently -- based on your operating environment.
6. Do not move your projector until the lamp has cooled (about five minutes).
7. Run your projector for two weeks and/or 20 hours shortly after your purchase. If the lamp is going to fail, it will usually occur within the first ten hours of operation. Lamp warranties typically last just 90-180 days from the date of purchase, rather than the first installation.
8. When you purchase a replacement lamp for your projector, remove the existing lamp and use the old lamp as your spare. If your projector is new, test the original lamp for the two weeks/20 hours before removing and storing as a spare.
