Abstract
A system and method for converting alternating current from at least two types of electronic ballasts for fluorescent bulbs into direct current for an array of LEDs. The device is assembled such that it can fit into existing fluorescent bulb fixtures. Alternating current from a contemplated electronic ballast can have one of two peak-to-peak voltages and the circuitry of the device will convert either alternating current into approximately the same direct current. In doing so, the array of LEDs is illuminated providing an LED alternative to fluorescent light bulbs.
