Abstract: An IC-rated airtight luminaire including a housing divided on a vertical plane to form two housing portions releasably coupled to one another to form an open cylindrical lower portion, a heat sink upper housing portion, and a heat conducting lamp assembly adjustment track enclosed within the housing. Disposed within the housing are heat sink walls slidably capturing a slide portion of a lamp assembly. A lamp holder integral with the slide bar includes a lens that directs a beam of light through an opening in a ceiling substrate in which the housing is installed, and an expansion ring rotatingly disposed around the open cylindrical lower portion of the housing engages and secures the housing in a ceiling substrate while also permitting the housing to freely turn within the expansion ring so as to allow adjustment of a beam of light directed from the lamp assembly.

Abstract: A recessed lighting unit that includes an adjustable lamp holder assembly, a fixture housing within which the adjustable lamp holder assembly is mounted; and a modular trim assembly, wherein the adjustable lamp holder assembly includes a pivot bracket detachably mounted in the fixture housing with a bolt that may be loosed and tightened for selected rotatable adjustment about a horizontal plane, and a vertical portion with a gear knob having a shaft disposed through an arcuate gear knob slot, and operatively connected to spur gear in mesh with gear teeth on an arcuate portion of a lamp support bracket, such that rotation of the gear knob rotates the lamp support bracket in a vertical plane.
