A 6-inch LED recessed downlight with emergency battery backup, designed for commercial and office spaces that require reliable egress lighting.
The Nuvo Satco Plus Series S21605 combines high-performance LED illumination with a built-in emergency battery backup, making it ideal for commercial environments where code compliance and safety are paramount. This 6-inch round fixture features field-selectable wattage (20.5W/18.2W/16.3W) and color temperature (2700K-5000K), along with a regressed baffle design that reduces glare. The white painted aluminum construction and frosted lens provide a clean, professional look.
Best for
- Commercial offices, hallways, and open-plan workspaces requiring emergency lighting
- Retail stores and showrooms where adjustable color temperature is needed
- Damp locations such as covered entryways or bathrooms (CETLus listed for damp locations)
- New construction or remodel projects with 120-347V electrical systems
- Spaces needing 90 minutes of emergency egress lighting per code
Not ideal for
- Residential living rooms or bedrooms where a decorative trim is preferred
- Wet locations (shower stalls, outdoor uncovered areas)
- Spaces with ceilings under 8 ft where the 3.43-inch height may be obtrusive
How bright is it?
Field-selectable output: 2200 lumens (20.5W), 1800 lumens (18.2W), or 1400 lumens (16.3W). At 2200 lumens, it's comparable to a 150W incandescent bulb, suitable for general ambient lighting in commercial spaces. The lower settings work well for accent or task lighting.
Light color and feel
Field-selectable color temperature from 2700K (warm white) to 5000K (daylight). 2700K-3000K provides a warm, inviting glow ideal for hospitality or retail; 3500K-4000K is neutral and crisp for offices; 5000K simulates daylight for task-oriented areas. With a CRI of 90+, colors appear vibrant and accurate. The fixture is dimmable with compatible dimmers (dual dimming support).
