LED projectors are becoming more and more popular. LED technology is being used in a wide range of products, including home theater projectors, business and education projectors, and even the emerging market of Pico projectors, and other mini projector systems. This has its benefits in a variety of fields, with several different uses. While most pico and pocket projectors utilize LED light sources, when it comes to larger projectors the number one player using LED light engines is Casio.  But that’s not quite correct as they use a hybrid design with both LED and laser. Lasers would be the other major solid state technology used, and it’s being used in some impressive, more expensive commercial projectors. Most manufacturers of LED projectors are claiming 20,000 or more hours of life expectancy for their light engines.  That’s about 4-6 times traditional lamps in conventional projectors.
