In many situations the perceived brightness of LED projectors can be up to twice the brightness of an equivalent lamp-based projector. LED brightness* specifications allow for a better comparison against lamp-based projectors, which do not take advantage of the enhanced brightness perception the Helmholtz-Kohlrausch (HK) effect creates.
Finally, the lamp-less LED illumination engine that powers the ML1500 does not require the inconvenience and cost of frequent lamp changes to maintain its optimal performance. It also doesn’t need lengthy warm-up and cool down cycles before and after every viewing due to its almost instant start up and shut down times.
