Abstract
A lamp including an elongate tube with a septum extending longitudinally therethrough to near the distal end of the tube. A pair of assembled leads and electrodes are positioned in the tube through the terminal end and the tube sealed. With an end cap on the distal end of the tube, an elongate cavity is formed extending along either side of the septum and joined at the distal end. A bend is made in the tube such that the ends of the electrodes extend into areas within the elongate cavity between the bend and the distal end of the tube.
