A 4-inch LED downlight with emergency battery backup for commercial offices, retail spaces, and damp-location installations where code-compliant emergency lighting is required.
The Satco Nuvo Plus Series S21604 is a field-selectable LED downlight that combines high-performance illumination with integrated emergency backup. Its white-painted aluminum regressed baffle and frosted lens reduce glare, while the 5-selectable CCT and 3-selectable wattage settings let you tune the light to your space. The self-diagnostic emergency feature provides 90 minutes of runtime, making it a reliable choice for code-compliant commercial environments.
Best for
- Commercial offices, conference rooms, and open-plan workspaces with drop ceilings or new construction
- Retail stores and showrooms needing adjustable color temperature for product displays
- Damp locations such as covered patios, entryways, or bathrooms (non-shower)
- Spaces requiring emergency battery backup for code compliance
- Remodel or new construction projects with 4-inch recessed housings
Not ideal for
- Wet locations (direct rain or shower exposure) - damp-rated only
- Residential living rooms or bedrooms where a decorative trim is preferred
- Spaces with ceilings under 8 ft if glare from the regressed baffle is a concern
How bright is it?
Field-selectable 800 to 1200 lumens - comparable to a 60W to 75W incandescent bulb. At 1200 lumens, it provides ample ambient light for a typical office cubicle or small retail area. The lower 800-lumen setting works well for accent or task lighting.
Light color and feel
Five selectable color temperatures from 2700K (warm white) to 5000K (daylight). 2700K-3000K gives a warm, inviting glow suitable for hospitality or residential-style spaces. 3500K-4000K is neutral white for offices. 5000K is crisp daylight for task-oriented areas. With a CRI of 90+, colors appear vibrant and accurate, ideal for retail or design studios.
Sizing and fit
Overall fixture dimensions: 4.96 in diameter x 3.23 in height. Fits standard 4-inch recessed housings. The 18-inch electrical whip provides flexible wiring. Suitable for ceilings of any height, but best for 8-12 ft ceilings for optimal light distribution.
