The specially designed wallwasher reflector for fluorescent lamps provides uniform wall illumination. When fitted with energy-saving lamps, e. g. fluorescent lamps or compact fluorescent lamps, these wallwashers are ideal for the provision of general wall lighting in museums, but also in shops and promotional areas. The illumination of a wall can be used for vertical visual tasks or simply to reveal the wall as a surface delineating the room.
Due to the reflections from the wall, indirect ambient lighting will produce uniform, diffuse light and a bright and welcoming atmosphere in the room.

Different colours of light can be produced with the varychrome wallwasher using RGB colour mixing technology. The diffuser and reflector combine to ensure that there are no coloured striations in the emitted light. The DALI-compatible luminaires have digital control gear through which each luminaire can be individually addressed - for instance using the ERCO Light System DALI with its integral ERCO Light Studio software.
