The Ultra-High-Performance lamp, a high-pressure mercury arc lamp often known by the Philips trademark UHP, was originally known as the ultra-high-pressure lamp,[1][2] because the internal pressure was as much as 200 atmospheres. It was developed by Philips in 1995 for use in commercial projection systems, home theatre projectors, MD-PTVs and video walls. Unlike other common mercury vapor lamps used in projection systems, it is not a metal halide lamp, but uses only mercury. Philips claims a lifetime of over 10,000 hours for the lamps. These lamps are highly efficient compared to other projection lamps – a single 132 watt UHP lamp is used by DLP manufacturers such as Samsung and RCA to power their DLP rear-projection TV lines, however Laser Display technology could be the superseding technology due to its increased longevity and display characteristics.
