High Intensity Discharge lamps are energy saving, about 5 x as bright as halogen lamps of the same power. Further, the lifetime is extremely high (6000-15000 hours compared to incandescent lamps with only about 1,000 hrs.)
The operation is only possible in luminaires with an appropriate supply unit. After switching on the high-pressure lamps need about 2 minutes to reach its full brightness and are not dimmable.
