LED projectors are very different than your typical DLP and LCD projectors as they do not require a typical projector lamp like their predecessors. Led projectors require less maintenance than their counterparts and have much longer "lamp life" which is typically around 20,000 hours for an LED light source versus 2,000-4,000 for a conventional projector lamp. LED projectors use the light harnessed by individual laser diodes to create the light that is usually created through a standard type of bulb or lamp.

What is a projector?
A projector simply projects images onto a wall or projection screen. Projectors are typically used to increase the image size for viewing by audiences. Projectors come in a variety of sizes, normally measured in Lumens which is the brightness of the light. This brightness will determine the size the image can project and the distance the projector can be from the screen. Slide projectors use light to project images from 35mm slides. Digital Projectors use light to project images from computers and DVD players.
