Abstract
A light column assembly including a hollow tube, a first endcap, a first optical lighting film, a second optical lighting film, and at least one light source is provided. The hollow tube includes a rear wall having an inner surface, a front wall extending opposite the rear wall, a first end, and a second end. The tube front wall also has an inner surface. The first endcap is coupled to the tube first end and includes a reflective inner surface. The first optical lighting film overlies the tube rear wall. The second optical lighting film overlies the tube front wall. The light source is coupled to the tube second end and positioned to direct a light beam having a predetermined beam spread angle toward the first endcap such that the light source light is substantially evenly emitted from the tube through the tube front wall.
