Prolonging Lamp Life

                Useful tips on prolonging lamp life

Never touch the lamp with your fingers, always use a cloth for handling. Deposits from fingerprints cause temperature “hot spots” and temperature gradient stresses the glass often resulting in earlier lamp failure.

Keep the air filters of your projector clean as block filters make the lamp overheat, possibly causing earlier lamp failure.  There should always be good airflow around the projector.

Always switch off the projector using the remote control and not by disconnecting the power. The projector will invariably go into a cool down mode where the image is turned off and the fan accelerates to cool the lamp in a controlled manner.

The temperature of an operating lamp is many 1,000’s of degrees, so if you disconnect the power to the projector, prior to the above process, the glass in the lamp will cool unevenly and will result in stress fracture, causing early lamp failure.   We are led to believe that you can shorten your lamp life by up to 50% simply by disconnecting the power instead of switching off the projector by remote control and allowing the natural cooling process to take place.

Lamp failure can also be due to mechanical shock and vibration.  A hot lamp filament is fragile and you should always ensure the unit is turned off and the lamp is cool before moving the projector.
