ABSTRACT:
A light fixture mounted in a niche can having two degrees of freedom of adjustment so as to provide universal orientation. A lamp housing is mounted to an inner ring which is mounted by a pivot assembly to an outer ring. The inner ring may be pivoted relative to the outer ring and locked in a particular orientation relative thereto. The outer ring is positioned in a niche can and may be rotated in the can about an axis which is substantially perpendicular to the axis of the pivot assembly. A lock assembly selectively locks the outer ring in the niche can to fix the orientation of the lamp. The inner ring may be removed from the mounting system of the pivot assembly for relamping. A retrofit stand can mount the outer ring such that it can be pivoted about an axis which is also perpendicular to the axis of the pivot assembly to again provide universal orientation of the light.
