Please bypass or remove the ballast when you use, otherwise the bulb doesn't light on.
The ballast in your fixture must be removed or bypassed for these adapters to function properly.
There are some LED Driver who can be compatible with the ballast, no LED Driver can be compatible with all the ballast.
So the best thing is bypass or remove once we want to change CFL to LED Lamp.
When we remove pin-based CFL, we only removed the lamp, the ballast is still working in front fixture; even we change to E27 CFL, there will be 2 ballasts, the light will not work.(E14 LED Candle light,E14 LED Bulb light,E14 LED Corn light, G24 LED Plug light,LED Bulb lihgt on sale)
