Abstract: A light source that is adapted to replace existing fluorescent tubes in an existing fluorescent light fixture is disclosed. The light source includes a plurality of LEDs mounted on a heat-dissipating structure, first and second plug adapters that mate with the florescent tube connectors of the fluorescent tube the light source is to replace, and a power adapter that converts power from a fluorescent tube ballast presented on the first and second plug adapters to DC power that powers the LEDs. The light source is powered from the output of the existing fluorescent ballast. The light source can utilize the existing metallic enclosure as a heat-radiating surface and/or direct air heat transfer from the surface of the heat-dissipating structure.
