1. An LED lighting device for replacing a fluorescent tube in a fluorescent lighting fixture having fluorescent fixture connectors and one or more of a standard fluorescent ballast and a magnetic fluorescent ballast, the LED lighting device comprising:
- a plurality of light emitting diodes;
a pair of contact pins at each end of the lighting device, said contact pins configured for mating with the fluorescent fixture connectors of the fluorescent lighting fixture; and
drive circuitry connected with said plurality of light emitting diodes and at least one contact pin of said pair of contact pins, said drive circuitry configured to provide an operating current to said plurality of light emitting diodes and to operate with a standard fluorescent ballast and a magnetic fluorescent ballast such that the lighting device is operable when connected to a fluorescent lighting fixture having a standard fluorescent ballast and operable when connected to a fluorescent lighting fixture having a magnetic fluorescent ballast.
