Discharge lamps have specific advantages over tungsten halogen lamps: in addition to high luminous flux and outstanding energy efficiency, they have a long service life. Lens wallwashers have special lens reflection systems to ensure uniform wall illumination. The light is spread by lenses and directed onto the wall by wallwasher reflectors. The Darklight reflectors of the lens wallwashers are visible from below and are glare-free. Due to the advantages of the new metal halide lamps in ceramics technology, these can be considered as suitable for illuminating walls as capsule or HIPAR lamps in lens wallwashers.

On lens wallwashers the Darklight reflectors that are visible from below are glare-free. Due to the advantages of the new ceramic metal halide lamps, they are as suitable for the illumination of walls as capsule or HIPAR lamps in lens wallwashers. All the Lightcast lens wallwashers have cast aluminium housings which are designed to provide optimum thermal properties according to their respective technical requirements. Other typical Lightcast features are the cast aluminium mounting ring and the four-point mounting which allows luminaires to be installed without tools. The Darklight technology combines the maximum visual comfort with the maximum light output ratio.
