摘要：

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° 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.
