lamp life is commonly discussed in terms of " half life". this projectors simply means the manufacture has set a limit on what they feel is the quality life of the lamp. if the lamp half life is 2000 hours, the lamp will generally last much longer although the brightness of the image may deteriorate. for example, on an lcd projector, the lamp half life is generally 2000 hours. the image brightness is normally above 85% of the original brightness up to 2000 hours. after 2000 hours you may see a drastic reduction in brightness. dlp projectors normally have less of a life and the brightness generally starts deteriorating before the half life. dlp & lcd digital light processing (dlp): the commercial name for this technology from texas instruments (ti): the technology inside is often referred to as either "micro-mirrors", used and lcd or dmd: it works this way: build a few hundred thousand tiny mirrors, and line them up in 800 rows of 600 mirrors each. now attach a hinge to each of those 480,000 mirrors. attach each of those 480,000 hinges to projectors its own very tiny motor! power each motor with electrostatic energy!
