Selected FAQ

Q:
How long should the projection lamp last in normal operation?
A:
The lamp should last up to 2000 hours in High Brightness mode and up to 3000 hours in Low Brightness mode.

To prolong the lamp life, you can do the following:
  • Turn the projector’s Sleep Mode setting on. See Customizing Power and Operation for more information.


  • Turn the projector off when not in use. Continuous 24-hour-a-day use may reduce the lamp’s overall life.


  • Make sure the projector is operated within the environmental requirement of 41 to 95°F (5 to 35 °C).


  • Set the projector’s Brightness Control to Low.


  • Make sure you correctly shut down the projector. This prevents premature lamp failure.


  • When you replace the lamp, make sure you don’t touch the lamp with your bare hands. The invisible residue left by the oil on your hands may shorten the lamp life. Use a cloth or a glove to handle the lamp.
