Abstract
An outdoor lighting system utilizing reflectors capable of producing a uniform distribution of light over a large area. The system reflectors employ parabolic reflecting surfaces utilizing a plurality of adjacent small concave and convex configurations for distributing the light in a uniform manner with a minimum of spillage, and a single reflector may employ three separate types of reflecting configurations to achieve the desired result at variable distances from the light source.
