Abstract
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.
