Nora Lighting NIO-4SC 4" Iolite LED Square Adjustable Cone Reflector

For homes and commercial spaces alike, the Nora NIO-4SC 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.
• California projects: it meets Title 24 (JA8) high-efficacy rules.
• Mixed-use spaces where you want warmer light in living areas and cooler light in work areas: 2700K, 3000K, 3500K, 4000K, 5000K, Comfort Dim (3100K-2000K), Comfort Dim (3000K-2000K) are offered.

Planning tip

Match the trim size to the housing size, then choose the look: open reflectors for general light, baffles to cut glare, lensed trims over showers. (our advice)
