An arc discharge headlamp capsule having arc tube, wedge, retainer, forward connector rod, insulating sleeve, RF ring, and base is disclosed. The wedge is formed to mate with an end of the arc tube, and be compressed along its exterior by the retainer. The wedge and retainer are sonically welded. The compressed wedge then gently, but firmly holds the arc tube. The thermal conduction from the arc tube is additionally consistent from lamp to lamp. The arc discharge headlamp capsule held by the wedge and retainer structure yields a lamp tube securely, and precisely held with even pressure.
