Abstract
A light fixture includes a fixture housing and at least one adjustable lighting head assembly coupled thereto. Each lighting head assembly includes a lighting head and a mounting assembly that couples the lighting head to the fixture housing. The lighting head includes a housing, a light source inserted therein, a cover coupled to the distal end of the housing, and an optic lens rotatably disposed between the housing and the cover which produces an asymmetric light output. The mounting assembly includes a rotatable mounting base, a pin head, and a pin extending from the mounting base to the pin head. The pin is inserted through a slot formed within the housing and the pin head slides within the housing along the length of the slot. Hence, the asymmetric light output is adjustable using the rotation of each of the optic lens, the sliding pin head, and the rotatable mounting base.
