Lighting Ballasts | HID and Fluorescent Light Ballasts

What is a lighting ballast? Lighting ballasts are devices needed by a range of lighting technologies, including HID lamps and fluorescent lamps. These ballasts help to safely start and operate a lamp, providing it with the correct voltage for startup and the right energy flow to run the lamp. The two most common types are magnetic and electronic ballasts, and they come in several start technologies to suit different purposes.
