Abstract
A trim assembly is mounted by a resilient spring in a housing, which is recessed in a ceiling, to support a light fixture. The trim assembly includes a cylindrical collar insertable within the housing and a flange with a central opening supporting one end of the cylindrical collar surrounding the opening being flush with the ceiling, when the trim assembly is mounted within the housing. A gimbal, which is located within and spaced apart from the collar, supports the light fixture. The springs are attached to opposite sides of an outer surface of the collar, for engaging an inner surface of the housing, to hold the trim assembly in place. In addition, the gimbal is retained within the collar by fasteners which allow limited rotation of the gimbal.
