for AC discharge lamps

AC discharge lamps - also known as metal halide lamps - belong to the group of high-pressure gas discharge lamps. Mercury arc and other metallic gases react with each other in a quartz bulb to produce light.

In comparison to other high-pressure gas discharge lamps, both their color reproduction and their light output values are very high. Therefore this type of lamps is counted among the most efficient lamps.

AC discharge are always to be operated with an Electronic Ballast. Schiederwerk provides ballast types of several power ratings and designs.
