    Abstract: A lighting fixture includes a first end plate and a second end plate that are coupled to and disposed on opposite sides of a reflector panel. Further, the lighting fixture includes a pair of elongated heat sinks that are coupled to the first end plate and the second end plate on opposite latitudinal ends of the pair of elongated heat sinks. Each elongated heat sink retains a longitudinal edge of a light guide and/or a plurality of LEDs directed towards the longitudinal edge. Further, the lighting fixture includes an optical device that is removably coupled to the lighting fixture such that the first end plate, the second end plate, and the pair of elongated heat sinks retain and overlap a perimeter of an optical device to prevent light leakage. The light guide is oriented horizontally and the optical device is oriented to receive light exiting the light guide.
