Electronic Ballast (4 pin CF)

Electronic ballasts for compact fluorescent lamps typically supply one or two lamps of a given wattage.  The type of compact fluorescent lamp powered by an electronic ballast is a lamp with a 4-pin connection which starts on a rapid start or program start circuit.  The wattage range is from 13 watts to 57 watts and the voltage range of the ballasts is from 120 volts to 277 volts.  These ballasts generally come in the form of a replacement kit often including brackets and short wire leads which allow the ballast to be accessed from the top, side or bottom.
