There are many ways to extend the lamp life of a projector. Use these guidelines to get the most out of your new lamp.
1. Operate not more than 3 to 5 Hours at a time
Extensive use without a cool down period can quickly reduce the life span of a projector and bulb. It’s the fastest way to burn out your equipment.
2. Clean Intake Vents, Exhaust Vents and Air Filters Regularly
All projectors feature intake and exhaust vents to help reduce overheating, There are also air filters available to protect delicate circuitry from debris. Clean the vents and air filters as often as your user manual instructs or at least once every three months to ensure long-lasting operation.
3. Operate the Device in a Clean, Dust-Free Environment With Good Airflow
Dust can clog intake and exhaust vents and restrict airflow in circuitry which can lead to overheating. Whenever possible, only use a projector in dust-free areas. Clean surfaces before setting up or mounting your projector to reduce debris near your device. If you must use the projector in less-than-ideal conditions, clean the vents and air filters more often than suggested. It’s equally important to ensure you use the projector in open areas that improve airflow.
4. Avoid Frequent Power Cycles
Every time you turn on the projector, the lamp strikes and reshapes the electrodes which slowly reduces the bulb’s lifespan. It’s better to leave it running if you need to take short breaks over hours of use.
5. Handle Bulbs With Care
The shock of dropping or striking a lamp can cause damage to the filament and reduce the number of hours it works. Be careful when handling bulbs whether they’re mounted in the projector, encased in a cage or bare. Don’t touch the bulb while replacing it, either. Oil from your hands can transfer to the lamp resulting in uneven heating and premature lamp failure.
6. Give Projectors Time to Cool Down Before Unplugging Them
Most projectors need some time to cool down before they’re unplugged. Unless the user manual states otherwise, don’t unplug the device until the fan stops running. A complete cooldown usually takes about ten minutes.
7. Use Lamp Economy Mode
Some projectors have a lamp-economy mode designed to extend a lamp’s life by up to 6,000 hours. It does so by reducing the bulb’s brightness by 20%. Most people won’t notice the difference in lumen output.
