How do I know when it is time to change my lamp?
Time To Change Lamp
Metal halide (high pressure mercury) projector lamps experience a gradual dimming of the image brightness as the lamp loses power and pressure builds up within the bulb. The dimming may be subtle but will nonetheless have increasing impact on your display. You should replace your lamp when the dimming of your image becomes noticeable.
Lamp Hour Counter
Occasionally, at the end of its life the lamp may fail altogether, usually due to temperature stresses. Most modern projectors have a built-in lamp hour counter which will let you know when it is time to change your lamp, and this counter should be reset every time the lamp is changed. Check your projector’s user guide for information about this feature. If you are unable to find the lamp hour counter simply contact one of our Lamp Experts who will be happy to assist you.
