The Nora NHIC-6LMRAT LED Diamond Series insulated ceiling housing is designed for use with Diamond Series trims (see Spec Sheet). The high quality, light weight unit's air-tight construction lowers energy costs by reducing the amount of air escaping through the ceiling. Rated for direct contact with insulation and combustive materials, the Nora IC housing is easy and quick to install. It works with standard leading-edge dimmers, dimming 5% to 100%, and trailing edge dimmers, dimming 10% to 100%. It includes quick connectors as well as adjustable bar hangers that can be re-positioned to 90 degrees.
