Abstract: An optic for a light-emitting diode (LED) array comprises an arrangement of optical structures for providing down lighting distribution from the LED array and a waveguide edge for providing up-lighting distribution from the LED array. Luminaires are described comprising an LED array and the optic. An overhead light fixture includes a driver assembly and a light-emitting assembly. The light-emitting assembly is operably connected to the driver and configured for downward emission of light from a light source of the light-emitting assembly. The light fixture is configured to be mounted to a canopy sheet of an overhead canopy, with the driver assembly disposed above the canopy sheet and the light-emitting assembly disposed below the canopy sheet. A bezel is optionally disposed around a lens of the light-emitting assembly, for aesthetic reasons and/or for controlling a degree of lateral emission of light from the light fixture.
