How to extend projector lamp life?

Projector lamps usually expire early because they are burning at too hot a temperature over the course of their lives. Below are some simple tips for extending your projector lamp life.
The single most important thing you can do to make sure your projector lamp lasts a long time is to mount your projector in a space with ample ventilation. Projectors that are mounted in corners, extremely close to the ceiling or in rooms with little to no air flow often cause the projector lamps inside them to expire early. 
Vacuum and Blow Compressed Air

Dust that gathers inside your projector can cause the projector lamp to burn at too hot a temperature over time which will cut its life short. The easiest solution to this problem is to vacuum your projector and blow it out with compressed air every now and then. Use your judgment, if you are using the projector often, complete this process more frequently. 
Change or Clean Your Filter Regularly
Almost every projector these days has a filter that prevents dust from getting inside the sensitive circuitry. The drawback to this is that if the filter gets clogged with dust it can cause the projector lamp to burn at a hotter temperature and diminish its lamp life. The filter on your projector is usually found behind a small rectangular panel that measures 0.5" by 6" long. 
Do Not Turn Your Projector On and Off Quickly 
Turning your projector on and off quickly can have devastating effects for your projector lamp. Replacement Projector lamps typically take about a minute before they are running in a stable current. Projectors have special ballasts inside them that ignite projector lamps at a high voltage and then run them at a low voltage. If you turn your projector on and off quickly it can cause the ultra-high pressurized mercury vapor to become destabilized, which will in turn cause your projector lamp to fail permanently. 
Run Your Projector in Economy Mode 
Most projectors these days have normal mode and economy mode. Economy mode usually makes the projector lamp emit a slightly lower brightness level and therefore can extend your projector lamp's life. If you are unsure if your proejctor has economy mode, please reference your projector's manual or contact the manufacturer.
