How does the ballast in a fluorescent light work?

Simple Explanation Hot and Cold Cathode Lamps: Fluorescent lamps work by ionizing mercury vapor in a glass tube. This causes electrons in the gas to emit photons at UV frequencies. The UV light is converted into standard visible light using a phosphor coating on the inside of the tube.

Correspondingly, what are the types of fluorescent ballasts?

There are two types of ballasts in the fluorescent family: magnetic and electronic. Magnetic ballasts are actually the older ballast technology. Both T12 linear fluorescents and two-pin CFLs use magnetic ballasts. Fluorescent T8s and 4-pin CFLs, meanwhile, use an electronic ballast.

What is an instant start electronic ballast?

As a result, they provide the most energy efficient solution to fluorescent lamp ballasting. The instant-start ballast uses 1.5 to 2 watts less energy per lamp than the rapid-start alternative. Instant-start electronic ballasts provide a high initial voltage (typically 600V for F32T8 lamps) to start the lamp.

What is a starter for a fluorescent light?

A choke is a coil of wire. Fluorescent tubes/lamps are filled with mercury vapor. They use electric charge to excite mercury atoms in order to produce ultra violet light. A glow starter or commonly known as starter is used in the tube light circuit to provide an initial current to filaments of the tube light.
