Wall mounted downlights can perform many different functions. Ceiling washlights provide an illumination of the ceiling with a high degree of uniformity. Additional adjustable cut-off shields restrict the projected beam to the precise section of ceiling to be illuminated. Uplights are designed for optimum efficiency and light distribution. As such, they are ideal for economical indirect lighting especially with metal halide or compact fluorescent lamps. Floor washlights are designed to provide safe illumination of traffic routes.
