Metal filament that emits electrons in a fluorescent lamp. Gas-filled lamp in which light is produced by the interaction of an arc with phosphorus lining the lamp's glass tube. Fluorescent light circuit. Path over which electric current flows to operate fluorescent lamps. A class of fluorescent.
Ballast provides a high starting voltage surge to quickly light the lamp.
All instant start lamps have a single pin base and can be used only with instant ballast. Rapid Start Lamps. Fluorescent lamps that glow immediately when turned on and reach full brightness in about 2 seconds. A fluorescent lamp in which the filament must be heated before the arc is created. The above Figure illustrates a fluorescent lamp with the conventional glow-tube starter.
