How to increase your projector lamp life
What is the actual life for projector lamps?
Let it be any projector lamp, each one has actual life hours. The projector lamp life is typically around 1,500 to 2,000 hours. Some newer models now a days claim 5,000+ hours of projector lamp life.
Manufacturers also provide a warranty covering their lamps for a certain number of hours or period of time. Projector lamps last even longer to the fullest of their life when they are operated in normal operating hours in a clean, dust free environment; whereas the projector lamps which are over used or are exposed to environmental contaminants are more likely to show a decrease in lamp life.
How do I know when it is time to change my lamp?
Metal halide (high pressure mercury) projector lamps experience a gradual dimming of the image brightness as the lamp loses power and pressure builds up within the bulb. The dimming may be subtle but will nonetheless have increasing impact on your display. You should replace your lamp when the dimming of your image becomes noticeable. Occasionally, at the end of its life the lamp may fail altogether, usually due to temperature stresses. Most modern projectors have a built-in lamp hour counter which will let you know when it is time to change your lamp, and this counter should be reset every time the lamp is changed. Check your projector’s user guide for information about this feature. If you are unable to find the lamp hour counter simply contact one of the experts of ITGear, we will be happy to help you.
How can I make my lamp last longer?
The following is a list of preventative measures you can take to reduce the likelihood of your projector lamp failing early:
- Do not allow the projector to overheat; the number one cause of lamp failure is excessive temperature stress.
- Allow the projector lamp to cool for at least 10 minutes after powering down, and never move the projector during this period or while the lamp is on. The lamp is much more susceptible to damage while it is hot.
- Operate your projector in a clean, relatively dust-free environment to prevent clogging of fans and air filters. These filters should be cleaned regularly.
- Allow plenty of space around the projector’s fan or exhaust so excess heat can be dispersed properly.
- Utilize the “economy mode” if it is available with your projector model and is appropriate for your situation. This mode decreases projector brightness but the lamp will last longer.
- Never leave a projector in very hot or very cold environments, for example in a car on a summer or winter day.
