Halogen - Metal vapour bulbs

Halogen - Metal vapour bulbs

Like high-pressure mercury vapour bulbs, metal vapour bulbs also belong to the group of gas discharge lamps. They contain halogen compounds and rare earths in order to increase the light output. In fact, they convert about 38% of their electrical charge into visible light. Therefore they are among the most efficient lamps ever. Since light is produced in a small space and thus almost a point light source is created, illumination is particularly intense, and light direction extremely precise. Thus, these special lamps are used e.g. in foyers, showrooms, museums and exhibitions, as well as shopping malls.
