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.

PL- Plug in light. CFL- Compact fluorescent lamp. PL is also a fluorescent lamp, but it is not compact. It is only a fluorescent lamp just like tube light. But its holder is different between tube light. If i want switch on the light then it will need ballast. But ballast is not necessary for any CFL. PL holder becomes only plug in or puss type. But CFL holder becomes variety. PL is back dated then CFL.
