nbspThe projector image seems dimmer than usual – what does this mean?
It may be time to replace your projector lamp. The brightness of metal halide lamps decreases during lamp life. With metal halide (high pressure mercury) lamps, you’ll notice a dimming of the image brightness as the lamp loses power. Some projectors allow you to check the number of hours your lamp has been used through the built-in menu system. Check your user guide for information about this feature.
