Abstract
A perimeter lighting system using monosymmetrical quasi-indirect light fixtures recessed in the ceiling of a room, near the walls, to direct light toward the walls and thereby cause it to be reflected from them at optimum elevation for maximum overall lighting of the typical working area in the room, thereby producing a high contrast rendition factor over much of the work task zone.
