ABSTRACT : The invention relates to a gas and/or vapour discharge lamp which is provided with a discharge tube and an outer bulb which envelops this tube, whilst the heat insu- lation in the space between the discharge tube and the outer bulb can be changed. According to the invention the heat insulation is changed by means of a reversible hydrogen getter which is located in the space between the outer bulb and the dis- charge tube. In this way it is obtained that the lamp can. either be operated without a stabilizing ballast or that it is less sensitive to variations in the mains supply. - 12 -
