Abstract

In a ballast for a discharge lamp, the characteristic values for the discharge lamp, such as the preheating voltage and the ignition voltage, are selected as a function of the environmental temperature in order to ensure operation of the lamp (9) which is as gentle as possible and hence a long life. <IMAGE>
