摘要: One of the low voltage output windings of a standard ballast circuit is coupled to one filament of a pair of series connected fluorescent lamps by an external current controller. The current controller acts to restrictively reduce the operating voltage applied to the filaments of one of the lamps to which it is connected, below firing value during start up operation and thereafter maintain a lower running voltage for the lamps without adversely affecting restart.
