Abstract
A light weight and modular light emitting diode (LED) light bar comprising an extruded aluminum LED fixture frame with integral cooling fins is disclosed herein. The light bar of the present invention is used for high density multi-layer hydroponic grow facilities to greatly improve the uniformity and intensity of light distribution over the plants and at a much reduced energy cost and less heat-to-space compared to conventional lighting used in grow rooms.
