6-1. Metal Halide Projector Lamp

If the projected image appears dark, the lamp may be getting old and in need of replacement. Under normal operating conditions, the lamp should last approximately 1000 hours. However, after time, the lamp brightness will slowly grow dimmer.

￿Note

The TEMPERATURE indicator will come on if the lamp becomes too hot. If this happens, wait for the fan motor to stop running, turn the power off and let the projector cool.
