Like any light bulb, a projector lamp has an expected lifetime. The number of hours you get from your projector lamp depends on the lamp itself and how you use it. Here are some tips to extend the life of your projector lamp.
Watch the dust. A projector operates best in a relatively dust-free environment. Be sure that the projector is not installed near any open windows exposing it to dust and pollen from the outdoors.
Avoid frequent on and offs. Every time you start up the projector lamp you create a power surge that puts stress on the connections in the lamp. Light up your projector when you are read to use it and avoid frequent switching on and off.
Check the heat. An overheated projector puts stress on the projector lamp and can cause it to explode. Make sure there is enough airflow around the projector particularly if it’s been permanently mounted. The mounting plates should never block the fan vent.
Give it a rest. Don’t operate the projector non-stop. Turn it off and let it stand for at least one hour ever 24 hours. An average use of four to five hours per day will ensure longer projector lamp life.
Let it cool. Your projector has a cooling fan that prevents the projector lamp from overheating. Allow the projector fan to run through its cycle and shut down before turning off the projector. Flicking the off switch before the projector has cooled down can cause the projector lamp to crack.
Keep it clean. The air filters on your projector are designed to keep the air flowing around your projector and prevent overheating. Keep them cleaned from dust and debris. Be sure to clean the air filters every 3 months or more often if there is a lot of dust. Regular maintenance will extend the projector lamp life.
Use the eco mode. Some projectors have an “Eco mode” or “Lamp Economy Mode” that reduces projector lamp brightness while extending the lamp life. Refer to the projector manual to switch the projector into “Eco mode”
