A plurality of fins integrally extends from an outer surface of the rear wall of the main body portion. A spindle with an internal bore integrally extends from the outer surface of the rear wall of the main body portion wherein the spindle is positioned among the fins. A light engine assembly is positioned within the main body portion and includes a plurality of LED light modules mounted to a printed circuit board. Each module comprises a LED and a lens extending from the printed circuit board, wherein the printed circuit board resides against an inner surface of the rear wall. A separate enclosure configured to enclose power management components is connected to a rear portion of the housing proximate the fins. The enclosure includes a housing wall arrangement and leads that extend through both an opening in the housing wall and the internal bore of the spindle, past the rear wall of the main body portion and to the printed circuit board. ## Claims ### Claim 1 A LED light fixture for use in commercial lighting settings, the LED light fixture comprising: a housing including a main body portion with a frontal flange, an internal receiver, and an array of fins extending rearward from the flange to define a rear receptacle that extends rearward from the flange, the housing further including a rear cover that encloses the rear receptacle; a light engine assembly mounted to the internal receiver, the light engine assembly having a plurality of light modules, wherein each light module includes both a LED mounted to a printed circuit board and an optical lens extending from the printed circuit board; a frontal lens cover affixed to the flange of the housing; and, a power supply residing within the rear receptacle and enclosed by the rear cover. ### Claim 2 (depends on 1) The LED light fixture of claim 1, wherein during operation, heat generated by the LEDs passes through the circuit board and then said heat is dissipated by the array of fins without the use of a fan. ### Claim 3 (depends on 1) The LED light fixture of claim 1, the housing having a side wall arrangement that extends rearward from the flange, wherein the side wall arrangement has a rectangular periphery that provides the housing with a rectangular configuration. ### Claim 4 (depends on 3) The LED light fixture of claim 3, the housing further comprising a pair of opposed protrusions positioned along the side wall arrangement, wherein each protrusion is configured to receive a fastener to couple with a mounting bracket that secures the LED light fixture to a supporting structure. ### Claim 5 (depends on 1) The LED light fixture of claim 1, wherein the frontal flange defines a first internal mounting surface that is recessed from a frontal edge of the frontal flange. ### Claim 6 (depends on 5) The LED light fixture of claim 5, wherein the frontal lens cover is received by the first internal mounting surface of the frontal flange. ### Claim 7 (depends on 1) The LED light fixture of claim 1, wherein the light modules are arranged in distinct groups. ### Claim 8 (depends on 1) The LED light fixture of claim 1, wherein the fins are arrayed such that there is a gap between adjacent fins. ### Claim 9 (depends on 1) The LED light fixture of claim 1, further comprising a separate box to enclose the power supply, said box residing within the rear receptacle, the rear cover operably connected to said box. ### Claim 10 (depends on 9) The LED light fixture of claim 9, wherein the box includes a front wall that is secured to at least one boss that extends between a rear wall of the main body and the front wall of the box. ### Claim 11 (depends on 10) The LED light fixture of claim 10, wherein the boss has an elongated configuration and is positioned among the fin array.
