Nora Lighting NHIOICDCP-415 4" Iolite LED Dedicated Chicago Plenum New Construction Housing, 20W

For homes and commercial spaces alike, the Nora NHIOICDCP-415 gives clean recessed ceiling light with nothing hanging down.

Typical spots: kitchens, living rooms, hallways, bathrooms, offices and retail ceilings. With a damp rating it also suits bathrooms and covered patios. Because the fixture sits flush or out of sight, it works in Modern, Transitional and Scandinavian rooms alike; the finish you pick decides how much it shows.

Where it works

• Residential remodels and new builds, plus offices, shops and hospitality spaces.

Planning tip

Pick the housing first: IC rated if it touches insulation, airtight where energy code asks for it, remodel style when the ceiling is already closed. The trim or LED module goes in after the drywall. (our advice)
