. The ballasts are good too because they don't push a whole lot of current into the flyback
what flyback
Typical ballast is just inductor when starter is on the heating elements increase the temperature inside the tube in the moment when going off the flyback spike igit the vapor in the tube then applayed voltage to tube is 110 V.
So the balast is not some kind of transformer or autotransformer.
