Ceiling luminaires in three sizes (115, 135 and 165 mm) for tungsten halogen lamps. Luminaires with anodized mirror reflectors of pure aluminium and hand-blown crystal glass. The crystal glass which is partially frosted inside provides optimum anti-glare. The larger part of the light is directed broadly downwards. The rest of the light is directed through the thick-walled glass laterally onto the ceiling and into the room, thus providing a high level of visual comfort.
