Before you order your replacement projector lamp, maybe our FAQs will help


Projector lamps can be replaced by you, the owner. Check your manual for more information on how to replace the bulb | housing | lamp.


My lamp looks fine but the projector does not light. I notice a "clicking" sound coming from the projector when I turn it on.


That could be the sound of your lamp ballast attempting to ignite the lamp but is unable. It is recommended that you try removing and reseating the lamp, or to try another lamp.


My projector seems to be functioning properly but then no light is produced.


Remove the lamp from the projector. Ensure that it has no cracks, discoloration or “smoky” appearance. It may have blown out.


The projector image seems dimmer than usual – what does this mean?


It may be time to replace your projector lamp. Projector lamps dim as they age. 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.


How many hours will my projector lamp work?


Just like any light bulb, projector bulbs have an expected operating time, called lamp life. This value is expressed in hours and represents the number of hours before the lamp is at half its original brightness.


The expected life of a lamp will vary based on the lamp technology and the projector; however, most projectors offer about 2000 hours. The lamp’s success rate is based on a bell curve, so that a majority of (but not all) lamps will meet the lamp life hours specified. Some lamps will fail sooner and this is part of the acceptable operating range of the rating.


For projectors that are used under normal operating conditions (no more than three to five hours per day in a clean, relatively dust-free environment) the lamp will have the greatest likelihood of lasting through its entire rated lamp life.


What can I do to help my projector lamp last longer?


There are several things you can do to increase your lamp life. Do not allow the projector to become overheated by ensuring that there is adequate clearance near the intake and exhaust vents.

Operate your projector in a clean, relatively dust-free environment.

Clean air filters every 3 months or more often if there is a lot of dust or contaminants in the room.

Striking the lamp ages the lamp as it causes slight changes to the shape of the electrodes that light the lamp, so light up your projector when you’re ready to use it and avoid frequent on and offs.

Avoid shock to the lamp or projector.

If your projector has this feature, Use “Lamp Economy Mode” to lengthen the life of the lamp by reducing its brightness. In most cases you will get a 50% increase in lamp life with a 20% reduction in brightness and you will not likely notice the reduced lumen output.

Allow the projector fan to turn off after you power down and before you unplug the projector. The only exception to this is a projector that is designed to keep the fan turning for a brief period after removing power.


Why do I see smudges or blobs on my projected image?

More than likely, what you are seeing is dust on one of your LCD panels. Try pausing your image so that these abnormalities are clearly visible. Then simply de-focus your projector in BOTH directions. You should see these blobs actually become a solid object either in the form of a string of lint or a spot of dust.


To avoid dust blobs from occurring, it’s important to perform routine maintenance on your projector. Cleaning of the filter with a vacuum on a monthly basis will help reduce accumulation of dust buildup.
