ABSTRACT:
A fluorescent lamp fires more quickly at low temperature and its service life is lengthened if the input terminals of a full-wave rectifier are connected to the lamp electrodes and a resistor and capacitor are connected in parallel circuit between the output terminals of the rectifier. The voltage pulses applied to the electrodes prior to firing are reduced in peak amplitude and broadened by the improved circuit.
