Abstract: A pinch-base lamp and method of making same where foils are sealed in the pinch, and secured to each foil are one end of a pole wire oriented generally parallel to the lamp axis and one end of a supply wire oriented at a right-angle to the pole wire. When the lamp is mounted the laterally extending supply wires are subjected to torsional instead of bending stress, thereby reducing the likelihood of fracturing the pinch, and the base of the pinch, being free of supply wires, may be ground to provide an accurate reference surface from the filament.
