The fixture includes an elongated housing having a pair of side walls with at least one fin to dissipate heat. Each side wall has a support member extending upward at angle from the side wall. A generally transparent cover is connected to the housing and extends between opposed ends of the housing. A first group of LEDs and a second group of LEDs are mounted to the first support member and the second support member, respectively. First and second interconnection board assemblies are affixed to respective support members beneath the group of LEDs. When the first and second interconnection board assemblies are energized by an internal power source, current travels from each interconnection assembly through fasteners to each group of LEDs for illumination. ## Claims ### Claim 1 An elongated LED lighting fixture comprising: an elongated external housing having a first external side wall and a second external side wall, wherein the first and second external side walls are arranged a distance apart to provide a void therebetween, and wherein each external side wall has at least one heat dissipating fin extending from an external surface of said external side wall, the housing further having a first support member angularly and integrally extending from the first external side wall and a second support member angularly and integrally extending from the second external side wall, wherein the support members terminate at an elevated central wall, and wherein the first and second external side walls, the first and second support members, and the central wall collectively define a U-shaped internal cavity of the housing with an open end configuration opposite the central wall;
