ABSTRACT A luminaire for providing uniform illumination of a horizontal or vertical plane surface is provided with a reflector having three distinct contours to provide optimum distribution of light flux. The first section is cylindrical and extends from 117° to 180° from nadir. The second section is a general contour curve extending from 180° to 270° from nadir and is used to redirect flux in the zone from nadir to 65°. The third section is a general contour curve extending from 270° to 355° from nadir and redirects the flux in the zone from 50° to 65° from nadir. The general contour curves in sections 2 and 3 are defined by fourth degree polynominal equations.
