An arc discharge lamp (10) has an envelope (12) including a base (14) containing lead-ins (16, 18). An arc tube (20) is positioned within the envelope (12) and has electrodes (22, 24) sealed therein. The electrodes have connection ends (26, 28) extending outside of the arc tube (20). A flexible primary electrical connector (30) is fixed between one of the lead-ins (16) and one of the connection ends (26) of one of the electrod es (22), the flexible primary electrical connector (30) having an area "A" subject to intergranular corrosion in the presence of oxygen and arc tube operating temperatures. A rigid secondary, intergrannular-corrosion-resistant electrical connector (32) is electrically connected between the lead-in (16) and the one of the connection ends (26) o f the one of the electrodes (22), the rigid secondary electrical connector (32) by-passin g the area "A" that is subject to intergranular corrosion.
