A luminaire having parabolic reflector elements to obtain strong crossed beams of reflected light forming the main components in a batwing distribution, with elliptical reflector elements to reflect light toward the center and mid-zones of the distribution pattern but not toward the peripheries, to improve the uniformity of the illumination on a surface and to reduce direct discomfort glare. The luminaire has special utility for uplighting, to illuminate a ceiling which can thus produce indirect illumination of an area, relatively free from veiling reflections.
