What to Do When a Lamp Malfunctions
In the event of a projector lamp malfunction, VESUN Lamps recommends referring to your User Manual for specific care instructions for your projection display and lamp. Always refer to your User Manual before replacing your lamp module to avoid complications with the lamp and your device. If you have misplaced your manual, many manufacturers make PDF versions of available on their websites.

Should I install the projector lamp myself?
For most projectors, installing a projector lamp is simple and usually only involves the turning of a few screws. However, keep in mind that the projector lamp housing and glass are very fragile, so you should consult your owners' manual or the instructions that came with the projector lamp, before you attempt to install the lamp yourself.
The most important precaution to note is when handling the projector lamp, NEVER touch the glass housing on the lamp. Oils from your fingers can cause the projector bulb to burn out or even burst prematurely. Handle the projector bulb carefully using the metal housing, and your lamp should last thousands of hours.
How many hours will my projector lamp work?
Just like any light bulb you would use for another purpose, projector bulbs have an expected operating time, called lamp life. This value is expressed in number of hours - typically 1000 to 2000 hours. Newer models are claiming 4000 hours of lamp life and more. The lamp's success rate is based on a bell curve, so that a majority of (but not all) lamps will meet the lamp life hours specified. Some lamps will fail sooner and this is part of the acceptable operating range of the rating.
For projectors that are used under normal operating conditions (no more than three to five hours per day in a clean, relatively dust-free environment) the lamp will have the greatest likelihood of lasting through its entire rated lamp life. Projectors that are used more often or are exposed to environmental contaminants are more likely to show a decrease in lamp life. Projectors that are operated 24 hours a day, 7 days a week are at the highest likelihood of lamp failure before the end of the rated hours.
How to Extend Projector Lamp Life？ |
1. Do not handle the lamp without gloves. Oils and deposits from hands and fingers can cause hot spots, which may result in premature lamp failure.
2. Keep the projector air filters clean. Clogged filters and/ or vents will not vent heat properly, and can cause the projector lamp to overheat and fail.
3. Do not place anything on top of the projector or in front of the intake or exhaust vents. This will cause the lamp to overheat and fail.
4. When you replace the lamp housing, make sure the new housing is seated completely. Apply pressure at the base of the housing until it is completely secure.
5. Hot lamps are very fragile. Always move the projector after the lamp has completely cooled. Shock and vibration applied to hot lamps may cause the lamp filament to break.
6. Do not unplug the projector until the lamp has properly cooled. After the projector has been shut off, the fan will remain on for about 5 minutes. This aids in cooling the lamp evenly and completely and decreases the chance of early lamp failure.
7. Do not turn the projector on and off frequently during presentations. Each time the projector is switched on, the inrush of power causes stress on the lamp filament. Try to minimize on/ off cycles.
8. Some projectors offer "low lamp" or "economy mode" options. Use them whenever possible. These options have been developed to extend projector lamp life. |
