ABSTRACT:
A low-voltage spotlight for use in substitution for a mains voltage PAR38 spotlight includes a casing which houses a removable low-voltage halogen lamp and metal reflector and apparatus for stepping down the incoming mains voltage. A lampholder for the removable halogen lamp is mounted on a metal casing which acts as a heat sink and also as a conductor of heat to the outer surface of the casing for dissipation. The spotlight is completely sealed for outdoor use in conjunction with a weatherproof PAR38 lampholder.
