The invention relates to a method and an arrangement ( 10 ) for monitoring a gas discharge lamp ( 22 ), comprising a control circuit ( 18 ) for detecting an electrical measured value assigned to the lamp voltage. The control circuit ( 18 ) is provided for detecting one voltage value prior to a change in current and a second voltage value after a change in current, or a setting time, and for producing a control signal which depends on the difference in the voltage values or on the setting time. In this way, a pressure within the lamp is monitored and a control signal can be produced which can be used to cool the lamp or to switch the lamp off. This methods detects inflation and therefore prevents an explosion of the lamp.
