Answer Posted / vinod kumar
CFL bulbs have an electronic circuit in the base of the bulb. This electronic circuit is called an electronic ballast. There is an electronic oscillator and a minature transformer that produces high voltage enough to ionize the gas in the tube, initially.
PL tubes are simply connected to the pins at the base. External ballasts must be used to supply the high voltage necessary to start the lamps.
