A fluorescent lamp's ballast works to control this. The simplest sort of ballast, generally referred to as a magnetic ballast, works something like an inductor.A basic inductor consists of a coil of wire in a circuit, which may be wound around a piece of metal.

en.wikipedia.org/wiki/Electrical_ballast

An electronic ballast uses solid state electronic circuitry to provide the proper starting and operating electrical conditions to power discharge lamps. An electronic ballast can be smaller and lighter than a comparably-rated magnetic one. An electronic ballast is usually quieter than a magnetic one, which produces a line-frequency hum by vibration of the transformer laminations.

Electronic Ballast is a device which controls the starting voltage and the operating currents of lighting devices built on the principle of electrical gas discharge. It refers to that part of the circuit which limits the flow of current through the lighting device and may vary from being a single resistor to a bigger, complex device.

How Does a Lamp Ballast Work? ... Electronic ballasts adjust the power frequency upward from the standard electrical current of 60 Hz and can boost it to 20kHz. This helps eliminate flicker in fluorescent light tubes, which has been shown to aggravate symptoms in people suffering from epilepsy. The lamp itself works more efficiently due to ...

Electronic ballasts are gradually replacing conventional magnetic ballasts (commonly known as choke) from the fluorescent tubes. They have higher efficiency as compared to magnetic ballasts and provide a flicker free start up to the tube. Also it does not produce the ‘hum’ sound which is very annoying with the magnetic ballast.
