A 4-inch square LED downlight with emergency battery backup for commercial spaces like offices, hallways, and retail environments.
The Satco Plus Series S21612 combines field-selectable wattage and color temperature with a built-in emergency battery backup, making it a versatile choice for new construction or remodel projects. Its white aluminum regressed baffle and frosted lens reduce glare while providing clean, uniform illumination. Dual dimming and self-diagnostic emergency features add convenience and reliability.
Best for
- Commercial offices requiring emergency lighting compliance
- Hallways and corridors where damp-rated fixtures are needed
- Retail spaces needing adjustable color temperature from warm to natural light
- New construction or remodel projects with 120-347V electrical systems
- Areas where 90-minute emergency runtime is required
Not ideal for
- Residential spaces where a smaller or non-emergency fixture would suffice
- Wet locations such as outdoor uncovered areas (damp-rated only)
- Spaces with ceilings under 8 ft where the 3.23 in height may be obtrusive
How bright is it?
Selectable output of 800, 1000, or 1200 lumens — comparable to a 60W to 75W incandescent bulb. The 1200-lumen setting is suitable for general ambient lighting in medium-sized rooms; the lower settings work well for accent or task lighting.
Light color and feel
Field-selectable from 2700K (warm white) to 5000K (daylight). 2700K provides a soft, cozy glow ideal for break rooms; 5000K offers a crisp, energizing light for task areas. With a CRI of 90+, colors appear vibrant and accurate, making it suitable for retail or art displays.
Sizing and fit
Overall dimensions: 4.92 in (D) x 4.92 in (W) x 3.23 in (H). Fits standard 4-inch square recessed housings. The fixture includes an 18-inch electrical whip for easy installation. Suitable for ceilings with standard joist spacing.
