Disclosed herein is a method of forming a LED-based light for replacing a conventional fluorescent bulb in a fluorescent light fixture including providing a heat sink of highly thermally conductive material having opposing longitudinally extending edges, mounting a plurality of LEDs in thermally conductive relation with the heat sink and enclosing the plurality of LEDs within a light transmitting cover such that the longitudinally extending edges engage an interior of the cover to support the heat sink within the light transmitting cover.
