What can I do to help my projector lamp last longer?
First of all do not allow your projector to become overheated. The most frequently cause of lamp failure is excessive heat. Please follow the instructions in your user manual for powering down the projector and make sure that the projector has an adequate cool-down period.
Operate your projector in a clean, relatively dust-free environment.
Please make sure that you clean the air filters regularly.
Utilize the "economy mode" if it is available with your projector model.
