The lamp operates by creating an electrical arc between two electrodes within the bulb that excites the pressurized mercury vapour and metal halides, and provides very high light output with greater efficiency than incandescent lighting units. The efficiency advantage is near fourfold, with approximately 85–108 lumens per watt of electricity ...
However, the lumen output of HID lighting can deteriorate by up to 70% over 10,000 burning hours. Many modern vehicles use HID bulbs for the main lighting systems, although some applications are now moving from HID bulbs to LED and laser technology. [2]
Their lamps have a range from 12 to 400 watts and operate at 250 kHz. ... the world replacing 400 watt, 750 watt and 1000 watt metal halide and high pressure sodium ...
High-pressure sodium lamps are quite efficient—about 100 lumens per watt, when measured for photopic lighting conditions. Some higher-power lamps (e.g. 600 watt) have efficacies of about 150 lumens per watt. Since the high-pressure sodium arc is extremely chemically reactive, the arc tube is typically made of translucent aluminum oxide.
As a result, metal-halide lamps have high luminous efficacy of around 75–100 lumens per watt, [2] which is about twice that of mercury vapor lights and 3 to 5 times that of incandescent lights [1] and produce an intense white light. Lamp life is 6,000 to 15,000 hours.
This example is a 71-inch, bi-pin, 100 watt model, the most common. Inside a preheat, bi-pin tanning lamp A high-pressure tanning lamp under power Tanning lamps (sometimes called tanning bulbs in the United States or tanning tubes in Europe) are the part of a tanning bed, booth or other tanning device which produces ultraviolet light used for ...
More than this: HID lamps like the metal halide lamps and high pressure sodium lamps have reduced reliability when operated at high frequencies in the range of 20 – 200 kHz, due to acoustic resonance; for these lamps a square wave low frequency current drive is mostly used with frequency in the range of 100 – 400 Hz, with the same advantage ...
