Video Projector Lamps
Depending on the brand or the model, video projector lamps can last anywhere from 2000 to 5000 hours. However, If the manufacturer specifies that your video projector lamp will last you for 2000 hours, you shouldn’t regard it as gospel truth. The truth is the lamp could call it a day even before it reaches the 2000 hour mark.
A projector replacement lamp is not the 60-watt bulb in your living room. It costs quite a bit, ranging from $200 to $600, depending on whether yours is a low lumen or high lumen projector. You won’t want to spend that kind of money before you fully get to enjoy your video projector.

Do you often transport your projector? If so, avoid leaving your projector in your car on a hot day. This not only applies to your projector, but also other electronic equipment. If you can’t carry the projector with you, leave it in the trunk of the car where the temperature is much lower. If possible, don’t park your car in a spot which is exposed to direct sunlight.

Beware of Cold Climate
Just as hot weather doesn’t agree with your projector, cold weather is also a culprit. If for some reason, your projector has been exposed to cold weather, don’t switch on your projector immediately. Allow the projector some time to return to room temperature before turning it on. If you switch it on immediately, the video projector lamp may explode. Be patient and wait until you feel that the projector has returned to room temperature before turning it on.

Breathing Space and Dust
Keep an eye on the fan exhaust of your projector. This is where heat accumulated in the projector is expelled. Don’t have the projector close to a wall. Without proper air circulation there’s the risk of the lamp overheating which eventually leads to a shorter lamp life. Have you projector at least three feet from the wall.
You will also want to check and clean the air filter pad of your projector. Remove any dust accumulated there so that there’s proper ventilation in the projector. Dust accumulated for months could lead to overheating of the lamp which could result in an explosion which in turn could start a fire.
