UHP (lamp)

The UHP, or Ultra High Performance, mercury arc lamp was developed by Philips in 1995 for use in commercial projection systems. 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.

Philips Digital Projection Lighting delivers innovative UHP lamp systems for professional or home theatre projectors, MD-PTVs and videowalls.

Devices using UHP lamps
