No, removing the ballast does not make your LED conversion consume less electricity. The ballast is an essential component which converts and regulates power delivered to a fluorescent tube. LEDs also require this power conversion and regulation; it can not be avoided. While it is true that the ballast is not 100% efficient (nothing is), the LED Tube Lights which require removing the ballast have, simply put, a ballast inside the tube itself. As a result, those products suffer from the exact same inefficiencies as the existing ballast.
