What is a Ballast?
In Fluorescent Lighting systems a Lighting Ballast is a device which is designed to regulate the amount of electrical current required to start and illuminate a lamp. Maintaining sufficient voltage in a linear lamp is an extremely important aspect of a light fixture’s operation. Without the implementation of a ballast, the light fixture would be unable to control the amount of electrical current. Not controlling the electrical current can cause an electrical surge that may result in the destruction of the lamp.
