Tips for longer 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 2 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 2 feet) stated in your owner's 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).
Schools and IT departments may wish to print these tips and keep them with projectors for end users to reference.

And Dr. K says, “NEVER, I repeat NEVER, attempt to 'defeat' the projector’s three-prong power plug to facilitate the use of a cheap, two-wire extension cord. Improper lamp discharging will dramatically reduce lamp life and could very likely damage the projector itself!"
