Abstract
Circuit arrangement for operation of discharge lamp comprising an input for connecting a supply alternating current voltage. A startup supply device is provided with an input and an output, where the input is connected to an input of a control circuit and the output is connected to another input of the control circuit. The startup supply device provides a startup supply voltage at the output of the startup supply device and hence reduces the stand-by losses.
