Abstract: The present invention involves a lighting kit adapted for installation into a conventional fluorescent lighting unit having a fluorescent socket and a ballast disposed in the lighting unit. At least one elongated body has fixture ends configured to engage a fluorescent socket. The elongated body supports a plurality of light emitting diodes (LEDs). A control unit, capable of receiving exterior control signals, electrically connects the LEDs to a power source for selectively dimming the LEDs, and is adapted to be mounted in place of the ballast. Dimming may be accomplished by control circuitry that recognizes repeated switching of a power source, and/or by a dipswitch on the LED device that sets the dim level. A method of retrofitting a fluorescent housing unit involves installing a LED device in the fluorescent housing unit and mounting an LED driver in the location configured to receive a conventional fluorescent ballast.
