... voltage envelope is 100 Hz. Because it is carried out the amplitude modulation of 50 Hz voltage, the spectrum of the signal contains frequencies of 150 Hz. Taking some reserve, we can say that the spectrum of the voltage distortion, characterized by dip and swell, does not exceed 300 - 400 Hz. ...

Electrical ballast
An electrical ballast is a device intended to limit the amount of current in an electric circuit. A familiar and widely used example is the inductive ballast used in fluorescent lamps, to limit the current through the tube, which would otherwise rise to destructive levels due to the tube's negative resistance characteristic.Ballasts vary in design complexity. They can be as simple as a series resistor or inductor, capacitors, or a combination thereof or as complex as electronic ballasts used with fluorescent lamps and high-intensity discharge lamps.
