Nora Lighting introduced a redesigned series of two-hour fire-rated downlight housings that can be used in either LED dedicated or line voltage installations. The new specification-grade Nora NFBIC firebox housings are smaller and lighter than previous models, and no longer have felt on the bottom of the frame. All units are double-walled and incorporate non-combustible fiber insulation to prevent the passage of flames, toxic gases and ignitable gasses into ceiling plenums.

With 4-inch, 5-inch and 6-inch apertures, the housings are compatible with Nora’s LED retrofit and surface mount luminaires. The NFBIC Series also includes a new 4-inch shallow housing, compatible with Nora’s 4-inch Onyx LED retrofit fixtures. The shallow housing is just 4 13/16” tall and accommodates narrow plenums.

All housings are airtight; rated for a minimum of two hours protection; and meet safety codes for commercial, multi-family and residential applications. NFBIC enclosures are IC-rated and cULus listed for wet locations when used with compatible reflectors. They meet or exceed ASTM E283 airtight requirements, and the noncombustible fiberfill also acts as a sound-canceling material, minimizing the transfer of noise between floors.

The housings accommodate a 1 ¾-inch maximum ceiling thickness and include (24) ½-inch bar hangers with captive nails and alignment feet. Dimming is available.
