Flourescent light currents

I know the older flourescent lights needed to be supplied by more current than you'd think by examining the power load. Beyond the power consumed in the bulb, there was a larger current being utilized but at an inductive phase angle so it is not power-consuming. Thus the volt-amp rating was maybe 2-1/2 times the power put out. This means you have to size the supply wire to yield this much current. Is the same thing true with the electronic balast screw-ins we have now?
