The invention relates to an operating method for fluorescent lamps and a corresponding ballast, in which the brightness of the fluorescent lamps (LP) is set to the desired value by varying the switching frequency of the inverter switches (T 1 , T 2 ). In order to prevent oscillations between different operating states in a critical dimming range, the power consumption of the fluorescent lamps (LP) is stabilized according to the invention by way of an additional control loop.
