Abstract
A durable LED light engine includes an printed circuit board including LEDs mounted thereon positioned between a substantially U-shaped top enclosure and a bottom enclosure. Once assembled together using alignment holes and projections, the open spaces in the combination of the substantially U-shaped top enclosure, the printed circuit board and the bottom enclosure are filled with a plastic sealant. Once cooled, the plastic sealant holds the combination of the substantially U-shaped top enclosure, the printed circuit board and bottom enclosure together.
