Starting and operating circuit for gaseous discharge lamps has device for quickly re-starting extinguished lamps while still hot. Circuit comprises ballast reactor, pulse transformer having a magnetic core formed with an air gap, charging capacitor and voltage sensitive switch device connected to the pulse transformer to form a series discharge loop with a portion of the transformer, and a storage capacitor connected at the output of the ballast reactor having sufficiently high capacitance to provide, in combination with the pulse transformer, for hot re-start of the lamp.
