1. An LED light engine comprising:
- a printed circuit board including;
a top surface on which is mounted at least one LED;
a bottom surface on which is mounted electronic componentry and insulated wires;
at least one alignment hole between said top surface and said bottom surface;
an edge surrounding said printed circuit board between said top and bottom surfaces;
a substantially U-shaped top enclosure including;
a top surface having at least one lens formed therein;
downwardly depending sides for surrounding said edge of said printed circuit board;
a bottom surface having at least one alignment piece constructed and arranged to pass through said at least one alignment hole in said printed circuit board;
a bottom enclosure including;
a top surface including at least one alignment receptacle formed therein and a pair of channels extending the length of said top surface;
said pair of channels constructed and arranged to position said insulated wires;
a sealant material enabling;
forming a strain relief around said insulated wires at either end of said substantially U-shaped top enclosure;
affixing said downwardly dependent sides of said substantially U-shaped top enclosure and said bottom enclosure one to another.
