A lighting system is designed to replace incandescent lighting by alternatively adapting existing recessed incandescent fixtures to accept more efficient lamps such as fluorescents, or using specially designed recessed lamp fixtures. In either case the invention addresses the problem of overheating of the on-board power stabilizing circuitry which almost universally occurs when an enclosed fixture designed for incandescent lamps is fitted with fluorescent replacements. Rather than installing the power stabilizer in the enclosure with the hot lamp, the power stabilizing circuitry is physically removed from the interior of the lamp housing and isolated at a remote position. The preferred embodiments house these electronics in a separate insulated ballast housing.

1. A recessed lamp fixture for mounting at least one lamp which requires a power stabilizer circuit to operate and defines a base, and which illuminates a target area through an opening in a ceiling panel through which passes a beam of light from said lamp therethrough, comprising:a) at least one lamp mount device defining a socket connectable to an available electrical power source for physically receiving and electrically powering a base of said lamp when inserted in said socket; b) said lamp when inserted into said socket having a top end and a bottom end; c) a lamp housing having upright oriented side walls that surround said lamp; said lamp housing having a bottom end that is open to allow said beam of light from said lamp to exit said lamp housing; said bottom end of said lamp housing being located no higher than the bottom end of said lamp; said side walls having an inner surface and an outer surface; d) a ballast housing having walls that define an enclosure having a bottom end; e) a power stabilizer circuit device for processing available power, said circuit device being substantially comprised of components housed in said ballast housing and operatively interconnected between said socket and a power source to intercept and stabilize power from said power source and deliver power so stabilized and usable by said lamp to said socket; f) means for supporting said ballast housing laterally positioned from said lamp housing so that it is not above said lamp housing in substantial thermal isolation from said lamp and said open bottom end of said lamp housing; g) said lamp fixture is of the recessed type which mounts a lamp spaced behind a room surface and said opening is defined in said room surface; and h) means for supporting said lamp housing above said opening in said room surface.
