Abstract
The present invention relates to a circuit arrangement for operating at least one lamp (LA), which has a first filament (W1) and a second filament (W2), it comprising an apparatus (10) for determining a variable which is correlated with the temperature of at least one of the two filaments (W1; W2). It also relates to a method for operating at least one lamp, which has a first and a second filament, a variable correlated with the temperature of at least one of the two filaments being determined prior to restarting the lamp.
