Abstract
A recessed downlighting fixture mountable in a ceiling between spaced joists or carried by T-bars and the like to direct light downwardly into an environmental space. The invention particularly takes the form of a pan assembly preferably formed of a thermoplastic material of a rigidity sufficient to support standard cans or reflector housings and associated lamping, electrical wiring inter alia. A junction box preferably formed of the same thermoplastic material is mounted to the pan assembly, access being gained to the interior of the box at opposite sides the box through positive latching doors which remain open to facilitate wiring operations within the box. The thermoplastic pan mounts adjustable bar hangers for rough-in of the downlighting assembly.
