A linear fixture for suspension from an overhead structure has a light weight and has electrical connectors capable of making easy plug electrical connections for power and network connection communications. The linear fixture is an elongated housing having a bottom wall, an elongated housing top wall and an elongated slot extending longitudinally along the elongated housing top wall. The housing is manufactured from an extrusion of aluminum thereby reducing the weight of the housing. The housing includes two or more housing supports having bottom and top surface portions respectively, conforming in shape to the housing bottom top walls. The bottom of top portions of the supports are adapted to engage or slide fit into the bottom and top walls so as to mate with the walls and provide support to the elongated housing bottom and top walls. The housing supports act to provide additional structural support for the top and bottom walls of the linear housing. The housing supports maintain the housing bottom and top walls in fixed relationship from each other. The housing supports are further adapted to be suspended from the overhead structure so as to support through the housing supports the elongated linear housing from the overhead structure. Preferably, the housing support comprises a one-piece plastic material, which reduces the weight of the fixture. The housing supports are adapted to receiving in mating relation an electrical plug whose terminals face outwardly for quick electrical connection with adjoining fixtures or a power source.

A lighting fixture assembly of claim 1, wherein each end portions of each housing support includes a peripheral flange with a flush outwardly facing surface enabling adjacent housing supports to abut in a linear fashion. 6. A lighting fixture assembly of claim 5, wherein each housing support includes a raised bridge surface extending across the elongate opening, said raised bridge surface providing a uniform continuum surface across the opening in the top wall and adjacent the opposing end portions. 7. A lighting fixture assembly of claim 5, wherein each housing support has a first socket and an electrical power plug connector seated in the first socket, the electrical power plug connector having an outward facing plug end facing outwardly of the elongate housing for connection with a power source and the electrical power plug connector having an inwardly facing plug end from which wires extending from the support into the elongate housing. 8. A lighting fixture assembly of claim 7, wherein each housing support has a second socket and a second electrical control connector seated in the second socket, the second control connector having a second plug connector facing outwardly of the elongate housing and control signal wiring extending from the support into the elongate housing. 9. A lighting fixture assembly of claim 1, wherein the bottom and top walls of the elongate housing have a cross-sectional shape in the form of an eyelet with the bottom wall and top wall meeting at corners of the eyelet, and the elongate opening extending along an entire length of the top wall dividing same into two spaced apart housing top wall portions. 10. A lighting fixture assembly of claim 9, wherein the housing supports on opposite sides of each elongate housing include mounting sockets facing inwardly of the elongate housing for supporting fluorescent lamps. 11. A lighting fixture assembly of claim 1, wherein each housing support further comprises ears extending inwardly of the elongate housing adjacent the bottom wall, each of the ears including an opening through to receive a fastener for securing the housing support in the elongate housing. 12. A lighting fixture assembly of claim 1, wherein each housing support further comprises ears that extend inwardly of the elongate housing adjacent the bottom wall, each of the ears includes an opening through which a locking screw passes, two elongate housing side walls extending adjacent the respective top wall portions, the two elongate housing side walls being secured relative to the top and bottom walls by the locking screws passing through the ears of the supports, and the side walls extending a predetermined distance beyond the top wall wherein a bridging surface extends across the elongate opening; riser members mounted to the bridge surface of the each of the first and second supports and extending between the side walls adjacent the end portions of the elongate housing, the riser members each including a second mounting socket facing inwardly of the elongate housing and additional fluorescent lamps mounted to the second mounting sockets to extend between the side walls. 13. A lighting fixture assembly of claim 1, each housing support further comprising an upper surface and an inner surface including a plurality of opposing locking tabs and/or a plurality of spring tab hooks formed on one or more of the upper and inner surfaces. 14. A lighting fixture assembly of claim 13, further comprising a bridge member positioned on the upper and/or inner surfaces and engaged with the opposing locking tabs and/or the spring tab hooks. 15. A lighting fixture for suspension from an overhead structure, the lighting fixture comprising an elongate housing having at least an elongate bottom wall and opposing first and second end portions; first and second supports mounted respectively to the first and second end portions, the first and second supports adapted for suspension from an overhead structure to support the elongate housing from the overhead structure, each of the first and second supports having a first electrical power plug connector having a front face comprising connection terminals facing outwardly of the elongate housing for connection with a power source, and a rear face with electrical wiring extending from the first electrical power plug connector through the support and into the elongate housing. 16. A lighting fixture of claim 15, wherein each of first and second supports comprise a first connector recess extending therethrough, said first electrical power plug connector being seated in the first connector recess. 17. A lighting fixture of claim 16, wherein the shape of the first connector recess conforms to the shape of the first electrical plug connector so that the first electrical plug connector is seated in at least partially mating relationship with the first connector recess. 18. A lighting fixture of claim 16, wherein the first connector recess has at least one pair of opposing support walls which engage the first plug connector to seat the first plug connector in the first connector recess, the first connector recess further including a pair of opposing converging cantilevered walls, each of the cantilevered walls extending rearwardly from a respective one of the pair of opposing support walls, to clamp against the first plug connector. 19.
