摘要： A method for operating a discharge lamp (1), wherein, during operation of the discharge lamp (1), an electrical heating current (IH) and an electrical discharge current (Id) are supplied at least temporarily to an electrode (6, 7). During undimmed operation of the discharge lamp (1), the value (SoS1, SoS2) of the sum of the squares of the electrical currents (I1, I2) supplied via power supply lines (8, 9, 10, 11) connected to an electrode (6, 7) is set in an interval of between 1.2 times the square of a test current (IT) predetermined for the discharge lamp (1) and 2 times the square of this test current (IT)
