420W HS420AR12-9 Bare NEC Projector Bulbs NP42LP

If you want your Projector Lamps work longer, please Note:

1. Do not allow the projector to overheat; the primary cause of lamp failure is excessive temperature stress.
2. 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.
3. Operate your projector in a clean, relatively dust-free environment to prevent clogging of fans and air filters. These filters should be cleaned regularly.
4. Allow plenty of space around the projector's fan or exhaust so excess heat can be dispersed properly.
5. 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.
6. Never leave a projector in very hot or very cold environments, for example in a car on a summer or winter day.
