A pulse discharge lamp, in particular an electronic flash tube, includes a substantially cylindrical discharge tube which, at each end, has an electrode which serves as a cathode or anode and which may be mounted on a lead through pin. Each electrode is constructed such that there is substantially uniform interval between the electrode and the discharge vessel wall radially of the electrode. On the external wall of the tube a longitudinal wire, strip coating, transparent coating or the like is carried as an ignition electrode and extend substantially along the interval between the other mentioned electrodes. At least one of the electrodes, or its mounting, has a metal band attached thereto, bent and spread in such a fashion that its distal end lies at a shorter distance from the ignition electrode than the electrode which supports the metal band.
