Projector Central, an online trade magazine for projection equipment, suggests that most projector bulbs have a life of about 2,000 hours. Epson claims its PowerLite projectorâs lamp lasts 5,000 hours and Delta makes an LED-based projector with a projected life span of about 20,000 hours. Before You Buy Consider that the lamp or bulb is often the most expensive part of a projector, and that unless you buy a projector with an extremely long (20,000-plus hour) lifespan youâll probably have to replace the bulb or lamp at some point.
