A ballast circuit for a fluorescent lamp including a rectifier-filter for coupling to an AC power supply to generate a DC voltage, an oscillator circuit coupled to said DC voltage for developing an RF oscillator signal, and switching signal means for developing concurrent oppositely phased switching signals at the frequency of said oscillator signal to drive series connected power transistors. The common output of the power transistors is coupled to energize a fluorescent lamp coil and regenerative feedback means for generating a signal to aid in switching the power transistors.
