7. The lighting platform of claim 1 wherein each respective downwardly extending end tip portion extends beneath an end of a respective threaded fastening device and is shaped and dimensioned such that, if the bottom cover is properly mated and aligned with the upper housing, the respective threaded fastening devices bite in to the respective downwardly extending end tip portions and pull the bottom cover and upper housing together, whereas, if the bottom cover and upper housing are misaligned, the respective threaded fastening devices will not bite and hold at all.

8. The lighting platform of claim 7 wherein each of the respective threaded fastening devices is a self-threading screw.

9. The lighting platform of claim 1 wherein respective upper and lower vertical edges are formed within said upper housing spaced apart from said downwardly extending surface and wherein a wire management clip is attached between said upper and lower vertical edges so as to define a wireway within the upper housing.

10. The lighting platform of claim 1 further comprising an end assembly comprising an end slip fitter, respective right and left side clips, an end cover and a central assembly comprising a slip fitter and respective right and left side clips wherein the end slip fitter and central slip fitter are retained by upper lips of respective side channels formed on an upper surface of the upper housing.

11. A lighting platform for mounting one or more LEDs comprising:

a bottom cover formed of heat transmissive material and having respective first and second side channels formed at opposite corners thereof, the first and second channels each comprising a horizontal bottom edge and a vertical side edge;

a circuit board carrying on or more LEDs mounted to an undersurface of said bottom cover;

an upper housing having formed of heat transmissive material and first and second downwardly extending end tip surfaces; and

respective first and second screws inserted through said first and second side channels and angled upwardly and threaded into said first and second end tip surfaces to thereby attach said bottom cover to said upper housing, said respective screws being tightened to a tightness selected to establish heat transfer between the bottom cover and upper housing for thermal management purposes.

12. The lighting platform of claim 11 wherein the best transmissive material for which the bottom cover and upper housing are formed is aluminum.

13. The lighting platform of claim 11 wherein each of said fastening devices is a self-threading screw.

14. The lighting platform of claim 12 wherein each of said fastening devices is a self-threading screw.

15. The lighting platform of claim 11 wherein the respective first and second channels each comprise a horizontal bottom, an outer vertical edge, and an inner vertical edge.

16. A lighting platform for mounting one or more LEDs comprising:

a bottom cover having respective first and second side channels formed at opposite corners thereof, the first and second channels each comprising a horizontal bottom edge and a vertical side edge;

an upper housing configured to match with the bottom cover and having first and second downwardly extending end tip surfaces on opposite sides thereof;

respective first and second fastening devices inserted through said first and second side channels and angled upwardly and threaded into a respective one of said downwardly extending end tip surfaces to thereby attach said bottom cover to said upper housing;

wherein each respective downwardly extending end tip portion extends beneath an end of a respective fastening device and is shaped and dimensioned such that, if the bottom cover is properly mated and aligned with the upper housing, the respective first and second fastening devices bite in and pull the bottom cover and upper housing together, whereas, if the bottom cover and upper housing are misaligned, the respective fastening devices will not bite and hold at all.
