magnetek ballasts


Preheat Ballasts

These units are designed for use with general fluorescent lamps and require the use of starters. These ballasts deliver an open-circuit voltage high enough to activate the starter to preheat lamp filaments to a temperature approximately 1750°F. After a few seconds, the starter opens the filament circuit. This provides an additional power surge to enable an electric arc to strike through the lamp and ignite it. Lamp current is then limited by the ballast to an operating level proper for the lamp.
