ABSTRACT:
A PAR38 light source assembly for use with a fixture having PAR38 socket connected to a ballast circuit for generating a ballast voltage. An electrically insulating housing supports a PAR38 screw base and encloses a CMH lamp and a circuit board providing a high voltage to ignite or re-ignite the lamp. The housing supports a reflector a lens wherein the lens, the reflector and the housing form an electrically insulating enclosure so that the PAR38 screw base is the only electrically conductive portion.
