A system operating in combination with a gas discharge lamp, such as a fluorescent lamp having electrodes therein, to effect ignition in a cold state without an ignition delay. Applied across the electrodes through a current-limiting coil is a voltage derived from a standard alternating-current supply. The supply voltage is also applied through an ignition switch to a starter coil inductively coupled to the current limiting coil to define therewith a step-up transformer, such that when this switch is closed, a high ignition voltage is imposed on the electrodes to produce an arc-discharge which heats up the electrodes. The resultant electron emission from the electrodes makes it possible to re-open the ignition switch after a brief interval, the lamp thereafter continuing to operate on the relatively low supply voltage.
