Claim Text:
1. A variable output light emitting diode (LED) assembly configured to be powered by a ballast, comprising: an alternating current (AC) to direct current (DC) conversion circuit configured to convert the output of the ballast to a selected DC current level; a plurality of LEDs electrically coupled to the AC to DC conversion circuit and powered by the selected DC current, wherein the plurality of LEDs is divided between a first board and a second board, wherein the first and second boards are electrically connected in series between end cap electrodes of the tubular housing, and wherein the first and second boards are configured such that the variable output LED assembly can placed into a fluorescent light fixture without regard for orientation of the of the variable output LED assembly between electrodes of the fluorescent light fixture; a selection circuit coupled to the AC to DC conversion circuit and having a plurality of selection settings, where each selection setting corresponds to a respective one of several DC current levels; and a tubular housing that entirely conforms to the shape of a standard fluorescent tube, and which houses the AC to DC conversion circuit, plurality of LEDs, and the selection circuit.
