The cost alone for a projector replacement bulb would be enough motivation for projector owners to look for ways to extend the life of their projector bulbs. Here is a list of tips that can help ensure that you are getting the most out of your projector's lamp and to postpone the need for your next projector replacement bulb:

• Take careful consideration when configuring your projector into your home theater or conference room setting. Ensure that there is plenty of space (typically two feet, but consult your owner's manual for model-specific measurements) between the projector's exhaust and intake fans and walls, ceilings, or enclosed compartments. Not following your projector's guidelines will cause overheating to the unit which will cause lamp failure.
• Do not unplug your projector until after the lamp has properly cooled. After switching your projector off, the fan may keep running for as long as five minutes in order to cool the bulb evenly and guards against bulb failure. Both of these tips will help the lamp last longer.
• Avoid turning your projector unit on and off frequently during presentations. Turning the power on causes a surge of energy to the lamp, exciting the bulb's filament. Doing this multiple times in a short period of time causes stress on the filament and will result in early failure of projector bulbs.
• Avoid moving your projector unit until the lamp has properly cooled. Hot bulbs are extremely fragile and the vibration caused by movement can cause the lamp's filament to break.
• Always clean your projector's intake and exhaust filters every 3 - 6 months, depending on how frequently it is used. Clogged filters do not vent heat properly, causing the projector to overheat leading to lamp failure and the need for a replacement bulb.
• Utilize "low lamp" or "economy mode" functions whenever possible. These options allow the lamp to run at a lower brightness, thus extending lamp life.
• Make sure that the ventilation holes on your projector are not blocked. This will help the projector in keeping the lamp temperature down.
• Do not touch "halogen lamps" with your fingers. The oil from your fingers will shorten the life of the lamp. You should make sure that your lamp is seated properly in the lamp socket. If it is not pushed down into the socket properly arcing may result and shorten the life of the lamp.
• Do not use the projector with the lamp cover removed.  At the lamp replacing, make sure that the screws are screwed in firmly. Loose screws could result in damage or injury.
• Do not open the lamp cover while the projector is suspended from above. This is dangerous, since if the lamp's bulb has broken, the shards will fall out when the cover is opened. In addition, working in high places is dangerous, so ask your local dealer to have the lamp replaced even if the bulb is not broken.
• To replace the lamp, turn off the projector and sub woofer and unplug the power cord. To avoid burns, wait at least one hour before opening the lamp door. The lamp inside this product contains mercury and must be recycled or disposed of according to local, state, or federal laws.
• When you buy a replacement lamp for your projector, remove the existing lamp and use the old lamp as a spare. If your projector is new, test the original lamp for the two weeks (or 20 hours), then keep that one in a cool, dry place for storage.
