Why choke coils are used in tube light?
A fluorescent lamp's ballast works to control this. The simplest sort of ballast, generally referred to as 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. If you've read How Electromagnets Work, you know that when you send electrical current through a wire, it generates a magnetic field. Positioning the wire in concentric loops amplifies this field.

This momentary application of high voltage is done by the choke coil along with the starter. When a tube light is switched on, current flows through the choke coil and starter and after a few seconds the starter switches off the current through the choke. The magnetic energy stored in the choke coil due to flow of current gets converted into electrostatic energy in the form of a high voltage which is applied across the tube light.
