An improved small profile hanger system for ceiling suspended lighting fixtures comprises a plurality of hanger assemblies having a support stem and a downwardly arced crossbar. The support stem and crossbar have a relatively small elliptical profile have two sets of wire holes, each set of wire holes having an inner hole and an outer hole overlapping the inner hole, the inner and outer holes defining an intervening gap narrower than the dimension of either hole. The holes are sized to receive an insulated wire; the intervening gap preventing the wire from crossing over into the adjacent hole. The wire holes of the support stem are in communication with the wire holes of the crossbar providing a fully enclosed wiring passage from a ballast box assembly installed above a suspended ceiling to energize a lamp in a diffuser depending from a pair of the crossbars.

A heat retaining sleeve for raising the cold spot temperature of a fluorescent lamp is comprised of a base end, a distal end, and a sleeve body sized and shaped to fit over the end of a fluorescent lamp or lamps where the lamp's cold spot exists. The sleeve creates a heat retaining air gap between the inner surface of the sleeve body and the lamp end or ends with the cold spot, and has sufficient length to so that, when fitted over the lamp end or ends, the cold spot temperature is elevated to a temperature that increase the lumen output of the fitted fluorescent lamp or lamps.

A luminaire, such as an indirect linear luminaire, is provided with a floating reflector assembly tied directly to securement points in the luminaire housing. The reflector assembly has a reflector element with tie down openings which overlay the reflector securement points and compliant spring-like retaining clips which overlap the tie down openings and which are secured at their center portion to the underlying securement points by a screw fastener. The width of the retaining clips are narrower than the tie down opening such that the center portion of the retaining clips can be drawn into and contact the housing securement points to provide good electrical grounding. The pressure contact of the retaining clips holds the reflector down yet permits it to float within the housing when the housing is distorted, such as by twisting, thereby avoiding distortion of the reflector.

An indirect luminaire having a housing with a top opening and a light source in the housing is provided with an exposed lens reflector system positioned over the top opening of the housing for receiving and redirecting source light from a position above the light source. The lensed reflector system includes an outer refracting lens element having a lens surface observable from below the luminaire and a substantially diffuse reflector substrate for the lens element. This system produces a light distribution pattern substantially governed by the internal reflection and refraction characteristics of the lens element and controlled brightness characteristics on the observable lens surface substantially governed by the diffuse reflection characteristics of the reflector substrate. A lens tower is suitably provided for holding the lensed reflective system in its operative position over the top opening of the luminaire housing. Preferably, the lens tower provides the diffuse reflector substrate for the lensed reflector system, with the lens element being removably attached to the lens tower so that the lens element can be readily replaced.
