About Solid State Light Engines

Solid state light engines are long life, so lamp replacement is not a factor.  They dim in brightness more slowly.  They also start up and have a usable image in just a couple of seconds, not more like 30 seconds to a minute for most conventional lamp based projectors.  These solid state projectors are truly more expensive per lumen, and that remains the case even when you figure in replacement lamps for the competition, but they do provide a long life, install and forget advantage, with what should be the lowest operational costs.  (They are typically more energy efficient as well.)
