Efficient light is light that is orientated around human per- ception and is generated with as little energy as possible. We perceive architectural spaces primarily by their vertical sur- faces, which is why wallwashing – as uniform vertical illumi- nance – is a central factor for efficient visual comfort. The
ability to build wallwashers, which use an asymmetrical light distribution to illuminate walls uniformly from the ceiling to the floor, requires considerable experience and expertise. In the ERCO Program, lighting design- ers will find what is probably the widest selection of wallwashers available, incorporating models
for indoor and outdoor areas, for recessed installation in floors or ceilings or for track mounting, and compatible with light sources ranging from fluo- rescent lamps to LEDs – every- thing for creative and efficient lighting concepts.
