A method of monitoring a gas discharge lamp, in which method an electrical test value related to the lamp operating voltage is detected, and to an arrangement for monitoring a gas discharge lamp comprising a control circuit for detecting an electrical test value related to the lamp voltage. A warning signal is generated when a test value is measured which corresponds to a clear reduction in the lamp voltage, for the purpose of better predicting the life of the lamps and the risk of explosion. The electrical test value may either be proportional (for example, a voltage which can be easily measured outside the lamp and which is preferably directly proportional to the lamp voltage) or inversely proportional (for example, the current supplied to the lamp) to the lamp voltage (burning voltage).
