What type of lamps are used in today’s projectors?

Almost all business and home theater projectors rely on lamps that use mercury. We’ll call them UHP lamps, but they are mercury vapor lamps. They are basically a cousin of the mercury vapor lamps used in street lights. When you read about the lamps in projectors, though, you’ll see them called UHP (ultra high pressure), or any of a half dozen plus acronyms. Trying to tell them apart by the different names, is mostly a waste of time. UHP, UHM, NSH, UHE, etc, are the same thing, in almost all cases.

There is a second type of lamp in use, on very high end, and extremely bright projectors, and these work differently. They are xenon lamps. Overall, they have a better color range than the UHP type lamps, and use xenon, not mercury.

These xenon lamps tend to be significantly more expensive, and have a shorter life than most UHP lamps. They tend to start at over $1000, and typically have a lamp life of 500 to 1500 hours compared to UHP lamps good for 1500 to 5000 hours.
