1. A light-emitting diode (LED) lighting fixture, comprising:
- a main housing comprising a top surface supporting one or more heat spreading members and an opposing bottom surface supporting an array of LEDs, the main housing extending along a first direction; and
at least one side housing attached to the main housing and extending from the main housing in the first direction, wherein cross-sectional thicknesses of the main housing and the side housing are substantially the same;
at least one constant current driver disposed in the at least one side housing, wherein the constant current driver is configured to deliver at least approximately 350 milliamps (mA) of constant current to each LED in the array of LEDs;
wherein the array of LEDs is configured to output light from the bottom surface in a direction that is different than the first direction, and wherein the combined light output from the array of LEDs is at least 15,000 lumens for high brightness applications.

Abstract
A light-emitting diode (LED) lighting fixture is provided as a potential solid state lighting (SSL) replacement fixture for a conventional HID lamp fixture. The LED lighting fixture includes a main housing having a bottom surface supporting an array of LEDs, a top surface and sides, and at least one driver provided in a side housing attached to a side of the main housing to drive the LED array. The thickness of the side housing is equal to or greater than the thickness of the main housing. A plurality of heat spreading fins is arranged on the top surface of the main housing.
