Abstract: This invention relates to a festoon lamp holder, and to a lighting system incorporating such a lamp holder. The lamp holder comprises a molded cap and base, and forms a pressure-tight seal with the supply cable, and a water-tight seal with a removably attached globe. Between the cap and base, lugs with detents engage within a groove, and through a camming action on a tapered post, engage permanently with a retaining means, thereby locking the detents within the groove. Probes between the cap and base pierce the cable, which may be used to support the lamp holder in a festoon lighting system. The lamp may be a low voltage halogen lamp and may also be formed as a festoon bulb held perpendicular to the lamp holder by hooked wires.

Abstract: A festoon lamp holder has a base provided with recesses either side of probes. A cap permanently fits to the base to provide a water-tight seal with an electrical cable passing in use through the holder. Power is provided from the cable conductors via feed-throughs for a bulb. A globe surrounds the bulb and provided with seals forms a gas-tight chanber for the bulb.
