A method for igniting and for starting high-pressure discharge lamps is provided. The method may include applying a takeover voltage to the lamp for a predetermined time of a burst; superimposing ignition pulses on the takeover voltage in such a way that the voltage of the ignition pulses and the takeover voltage are added up and an interruption being provided between two bursts; and changing the ignition pulses from burst to burst or within a burst from the positive half-cycle of the takeover voltage to the negative half-cycle of the takeover voltage, and vice versa.
