Mercury vapor lamps

Mercury vapor lamps belong to the  traditional type of high-intensity discharge lighting, and they are mainly used primarily for street lighting.

Mercury vapor lamps can produce 50 lumens per watt approximately. They cast a very cool blue/green white light. Most of the indoor mercury vapor lamps in arenas and gymnasiums have been replaced by metal halide lamps which have a higher color rendition index and a higher efficacy. However, like high-pressure sodium lamps, mercury vapor lamps have longer life hours (16,000-24,000 hours) than the metal halide lamps.
