Replacement Lamp Sanyo PLC-XU73 Projector
Sanyo PLC-XU73 is a great presentation projector with a bright picture. It is compatible for office use such as a short focus lens, however it may not be as useful for the home theatre enthusiast. The lumens rating is very high and can really make most projectors appear dull in most light settings. The key to its brightness is its 200W projector lamp which is strong enough yet still energy efficient and will last roughly 2000 hrs.

Almost all home theaters and business organization depend on UHP lamp. These are lamps that use mercury. In projector you will see them called UPH (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

Another type of lamp are very high end, and extremely bright projectors, and its totally different. They are Zenon lamps. Comparatively Zenon lamps have a better colour range that mercury lamp (UHP). They are expensive and have very a shorter life when compared to 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. They also are usually only found on projectors that sell for more than $10,000
