Projector lamp
Your projector lamp likely needs to be replaced if your
projector image seems dimmer than usual. If you have a newer model of
projector, it may have a feature that allows you to check how many hours
your projector lamp has left in it. If you have this feature, definitely
use it before you decide to replace your projector lamp.
To ensure that your projector lamp lasts as long as possible, keep
it from becoming overheated. Excessive heat can cause lamp failure.
Make sure your projector gets an adequate cool down period. Also, your
projector lamp will last longer if you keep your projector in a clean
and dust-free environment, and be sure to clean your air filters regularly.
Consider using the “economy mode” if your projector model
has it.
