Magnetic fluorescent ballast for circline lamps
7 in stock
A ballast transforms line voltage to a start-up voltage that is needed to operate a fluorescent lamp. A magnetic ballast (also called a choke) contains a coil of copper wire. The magnetic field produced by the wire traps most of the current. As a result, the right amount gets through to the fluorescent light.
