Ballasts & Drivers
An electrical ballast or driver is a device intended to limit the amount of current in an electric circuit.
A familiar and widely used example is the inductive ballast used in fluorescent lamps, to limit the current through the tube, which would otherwise rise to destructive levels due to the tube's negative resistance characteristic.
Emergency Lighting is now selling programable LED drivers that will allow your LED lighting to be dimmable. When your driver goes out let us know the milliamps of the driver and we can program the LED to the exact milliamps.
