A 28-watt, 8-inch LED recessed downlight with emergency battery backup, designed for commercial new construction and remodel projects where code-compliant egress lighting is required.
The Nuvo Satco Plus Series S21606 combines field-selectable wattage and color temperature with a built-in emergency battery, making it a versatile solution for offices, hallways, and other commercial spaces. The white-painted aluminum regressed baffle and frosted lens reduce glare while the self-diagnostic emergency feature ensures reliable backup for up to 90 minutes. Dual dimming capability and a high 90+ CRI deliver comfortable, accurate light.
Best for
- Commercial offices, conference rooms, and open-plan workspaces needing code-compliant emergency lighting
- Corridors, lobbies, and egress paths where 90-minute emergency runtime is required
- Retail and hospitality spaces with 8-12 ft ceilings, where field-selectable CCT (2700K-5000K) allows tuning to match decor
- New construction or remodel projects with 120V-347V supply, using the included 18-inch electrical whip
- Damp-rated locations such as covered patios, entryways, or bathrooms (non-shower)
Not ideal for
- Wet locations (direct rain, shower stalls) - damp-rated only
- Residential rooms with ceilings under 8 ft - the 4-inch depth may protrude in shallow plenums
- Spaces requiring a decorative trim - this is a functional commercial downlight with a regressed baffle
How bright is it?
3200 lumens at 28W - comparable to a 200W incandescent floodlight, bright enough for general ambient lighting in commercial spaces up to 200 sq ft per fixture. The field-selectable wattage (28W/25W/20W) lets you reduce output to 2200 lumens for lower-light areas.
Light color and feel
Field-selectable among 2700K (warm white), 3000K, 3500K, 4000K, and 5000K (daylight). 90+ CRI ensures accurate color rendering for tasks like reading or product displays. Dual dimming compatible with most LED dimmers for smooth fade control.
Sizing and fit
9.76 x 9.76 x 4.02 inches overall. Fits standard 8-inch ceiling cutouts. The 18-inch electrical whip provides flexible junction box placement. Suitable for ceilings with at least 6 inches of plenum depth.
