ABSTRACT:
Add-on device for connection in series with one lamp of a two-lamp rapid-start fluorescent light system to reduce by a predetermined amount the nominal power consumption and light output of the system. The device has normally closed relay contacts which are in circuit with one of the electrodes of one of the lamps and a power-reducing capacitor is in shunt with one of the relay contacts. Upon turning on the system, a solid-state time-delay and relay-coil-energizing circuit is actuated which opens the relay contacts only after the lamps have been started and are operating with nominal power consumption. This places the shunt capacitor in series with the operating lamps and reduces the nominal power consumption by a predetermined amount.
