Projector Lamps FAQ                                                                                        
1. What is a projector lamp?
 The technical description of a modern projector bulb is that it is an ultra-high pressure mercury vapor ARC lamp. Projector lamps are categorized as either metal halide lamps or ultra-high pressure mercury vapor lamps. Philips has trademarked the name "UHP lamp" for their projector lamps
2. How many hours will my projector lamp work?
 Just like any ordinarily light bulb you would use for other purposes, projector bulbs have an expected operating time, called lamp life. This value is expressed in number of hours - typically 1000 to 2000 hours. Newer models are claiming 4000 hours of lamp life and more. The lamp's success rate is based on a statistical bell curve, so that the 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 and other could live even longer.
  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. Projectors that are used more often or are exposed to environmental contaminants are more likely to show a decrease in lamp life. Projectors that are operated 24 hours a day, 7 days a week are of course, at the highest likelihood of lamp failure before the end of the rated hours.

4. How Do I Know When To Replace My Lamp?
  The modern projectors will have a built in timer that keeps tracks of the projector lamp time usage. Once the timer reaches a certain point, usually a few hours before the expected lamp life, a message will display on your projector screen. The warning message is usually a good indicator that you should jump online and start looking for new projector lamp.
  If it is annoying, it is possible to get rid of the warning message; you can do this by searching your projector's manual or navigating through the onscreen menu if your lamp is still functioning.
  Sometimes projectors will shut down the projector lamp when the timer reaches a certain point, even if it has not been totally exhausted. In these cases, it is useful to reset your lamp hour counter as it may increase the amount of life you get from your projector lamp.
   We recommend that if you are using your projector lamp for important presentations, weekly events or even at your home theater, it is smart to have a back-up projector lamp in stock in order to have a continuous projector operation.
