All pin-based CFL, like G24d Gx24d GX24Q GX23 G23 are lamp-ballast separated, but all screw-in E26 E27 are lamp-ballast integrated. ballast is a must to start a high voltage(600V-1500V 1ms) to light up the CFL, but it is dangerous for LED Lamp. Because LED Lamp are built with LEDs and Driver which is transforming the 100-240V AC to DC for LEDs. So the LED Driver input should be 100V-240V or 85-265V, so 600-1500V will be too high, and easily destroy the led lamp.
