Abstract:
A light fixture includes a housing and at least one adjustable light assembly coupled thereto. Each light assembly includes a light source and an optic lens that is disposed over at least a portion of the light source. At least a portion of the lens is positioned external to the housing. The lens is rotatably adjustable about an axis extending perpendicular from the lens and includes a portion of the light source. The lens emits an asymmetrical light output. A light source holder may be included as part of the light assembly and is used to couple the light assembly to the housing. The light source holder includes a first surface, a second surface opposite the first surface, and an aperture extending therethrough. The light source is positioned adjacent the first surface over the aperture while the lens is positioned adjacent the second surface over the aperture.
