Apollo new construction housing for use in insulated ceilings can be in direct contact with insulation. Airtight 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.
