Abstract
A light for an industrial stringlight includes a cap having wire channels receiving insulated conductors. Non-interchangeable contact elements are placed in a screw-shell adapted to hold a lamp, and the cap and screw-shell are forced together. The cap is secured to the screw-shell, and insulation-piercing points on the contact elements establish electrical continuity with their associated conductors. The assembly is then overmolded for protection and sealing. A lamp guard is assembled to the overmold and has a bottom section hinged about a horizontal axis to permit replacing the lamp from beneath.
