1. Wear gloves when you handle lamp. There chances of getting hot spot because of oils and other deposits from hands and fingers. Handle carefully.
2. Always keep projector air filters clean. If it’s not clean then it will not vent heat properly. This may cause damage to the projector due to over heat. Also make sure that you are not keeping anything in front of your exhaust vent. This will also cause over heat.
3. Close your lamp housing properly. If its not sealed properly then there are chances of getting dust.
4. Do not move your projector when your lamp is too hot. Hot lamps are very fragile. Small vibration may affect the lamp filament to break. So move when it’s completely cooled.
5. 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.
6. Do not turn the projector on and off habitually during presentations. Each time the projector is switched on, the supply of power causes stress on the lamp filament. Try to minimize on/ off cycles.
7. Some projectors offer “low lamp” or “economy mode” options. Use them whenever possible. These options have been developed to extend lamp life.
