<p>A low cost metal halide lamp comprises a discharge tube (20) comprising a discharge chamber in which ionizable materials are enclosed, and a narrow tube (21a,21b) projecting from the discharge chamber, and an electrode arrangement (35a,35b) inserted into the narrow tube (21a,21b) and sealed with a sealing frit (27a,27b). One end of the electrode arrangement (35a,35b) is positioned within the discharge chamber (20). A portion (38a,38b) of the electrode arrangement (35a,35b) sealed with the sealing frit (27a,27b) comprises a conductive member formed by curving a thin conductive sheet.
