Abstract: A lighting assembly configured to provide a cove lighting effect includes a housing configured to releasably couple a light apparatus comprising a light source coupled to a heat sink. The housing comprises an apparatus portion configured to accommodate the light apparatus, and a wireway configured to accommodate supply wiring for the light apparatus. The housing further includes a trough configured for mounting the housing and for coupling a first housing to a second housing. A light apparatus can include a releasably coupled lens. A light apparatus can releasably engage the housing, and can be removed from the housing when a light source is replaced. A housing front plate can conceal a housing back plate so that only the front plate need be embedded at a wall.

Abstract: An adjustable recessed light fixture comprises a lamp positionable in orientations wherein the light beam is inclined obliquely relative to a vertical axis, and wherein the inclined light beam can be rotated about the vertical axis. A movable stop is provided which enables the lamp to be rotated in a complete 360.degree. range of rotation. A housing which covers the light fixture includes a removable top wall which provides an effective thermal insulation for the housing. A trim ring is installable such that torsion springs of the trim ring are effectively held within a rotatable spin disc of the light fixture. The lamp can be rotated about a horizontal axis in a manner wherein only a minimal portion of a light beam is cut off by a reflector. A bar hanger for hanging a light fixture frame to a ceiling joist includes relatively slidable rails, wherein ends of the rails can be broken off to shorten the bar hanger without having to disconnect the rails from one another.
