<p>One (46) of the low voltage output windings (42, 44, 46) of a standard ballast circuit (16) is coupled to one filament (60) of a pair of series connected fluorescent lamps (10 and 12) through a regulating capacitor (62) and a current rectifying diode (64) which are connected in series across such output winding (46) and in parallel to the one filament.</p> |
