Apollo Non-IC new construction housing require a minimum clearance of 3" from thermal insulation. Air-tight construction provides energy savings by reducing the flow of air through the ceiling. Adjustable LED mechanism allows for 361° horizontal rotation and 45° vertical aiming. Optimized TIR optics directs the light through the center of the aperture for maximum efficiency and low aperture brightness.
