Abstract: Downlight and downlight wall wash reflectors particularly useful with compact fluorescent lamps and other large-area light sources, the reflector optics of the invention maximize the efficiency of the luminaire while providing brightness control and avoidance of high angle glare or "flash". Downlight reflectors according to the invention provide a truly uniform illuminance distribution across the illuminated area when applied in a rectangular grid with maximum use of available light by providing an upper amplifying reflector section which reflects normally underutilized light to a lower distribution reflector section which radiates a large percentage of generated light effectively from the bottom of the light source, thus reducing the apparent size of the light source and increasing optical control. The lower reflector section reflects light only into zones where the light is needed and avoids high angle zones, most of the light being reflected into zones from 35.degree. to 45.degree.
