Abstract
A luminaire includes an electrical base, an optic, and a heat sink disposed between the base and the optic. The lens has a first curved portion, a second curved portion and a third portion. An LED light source is coupled to the heat sink with LED modules arranged to direct light in the same direction. A frustoconical member having a reflective outer surface is disposed between the lens and the LED light source wherein the LED light source has LED modules disposed to emit at least a portion of light toward the reflective outer surface such that light is emitted with a substantially even luminous intensity in a 0°-135° zone.
