Nora Lighting NHIC-4LMRAT 4 in Ic at Led Housing 120-277V

Product Description

The NORA LIGHTING NHIC-4LMRAT is a 4-inch IC-rated, airtight (AT) LED-dedicated new construction recessed housing designed for line-voltage applications from 120 to 277 volts. It supports both Triac and ELV dimming protocols, making it compatible with a wide range of low-voltage and standard dimmer controls. This housing is intended for new construction installs where the fixture is positioned before drywall is hung. Electricians and lighting contractors are the primary trade installing this type of housing in residential and light commercial ceiling applications.

This housing is suited for new construction framing installations in wood-joist or metal-stud ceiling assemblies. The IC rating allows direct contact with insulation, and the AT (airtight) rating meets energy code requirements that restrict air leakage through recessed fixtures. Typical applications include residential bedroom, kitchen, and hallway lighting as well as light commercial office and retail environments where insulated ceiling assemblies are required by code.
