Projectors that use light-emitting diodes instead of traditional high-pressure bulbs as their light source have a number of advantages. They tend to run cool and can be small. Their LED bulbs typically last 10,000 hours or more and are able to withstand the bumps and vibrations of travel. In exchange for these benefits, they have one significant drawback. LED projectors typically have much lower light output, or brightness, than comparably priced projectors using traditional lamp technologies. As such, maximizing their light output and minimizing competing light sources can be important. Writer Bio
