Satco S21615 38W 10 Inch LED Commercial Downlight Retrofit, Field Selectable CCT 2700K-5000K Warm White to Natural Light, Dual Dimming, Emergency Driver, 4200 Lumens, White, 120-277V

The Satco S21615 is a 10 inch LED commercial downlight retrofit with integrated emergency driver, designed for indoor commercial environments that require high lumen output, square form factor consistency, and life safety functionality. The fixture features field selectable wattage and color temperature, allowing installers to configure performance on site to meet layout requirements, energy codes, and design intent. Dual dimming supports phase cut dimming at 120V and 0-10V dimming across 120-277V systems. This square downlight delivers up to 4200 lumens with a 90+ CRI and a wide 100 degree beam angle, supporting uniform illumination and accurate color rendering across selectable color temperatures from warm white to natural light. The aluminum housing with polycarbonate lens is air tight, IC rated, and suitable for damp indoor locations, supporting installation in a wide range of recessed ceiling applications. Rated for 50000 hours, the S21615 includes a 90 minute emergency battery runtime for power interruptions. Electrical performance includes power factor greater than 0.9, total harmonic distortion below 30 percent, and built in 2.5KV surge protection. The fixture is Energy Star certified, Title 20 listed, T24 compliant, cETLus listed, and lawful for sale in California.

• Field selectable wattage and color temperature allow installers to configure the fixture using integrated switches, with selectable wattage settings of 38W, 31W, or 26W and selectable color temperatures of 2700K, 3000K, 3500K, 4000K, or 5000K, reducing SKU count while supporting consistent lighting performance across different rooms, ceiling heights, and application requirements within the same commercial project.
• Integrated emergency driver provides up to 90 minutes of emergency illumination during power outages, supporting life safety lighting requirements in corridors, stairwells, offices, and common areas where continued illumination is required to guide occupants safely during emergency conditions or loss of normal power.
• Dual dimming capability supports phase cut dimming at 120V and 0-10V dimming across 120-277V systems, allowing compatibility with a wide range of commercial dimming controls while maintaining smooth, stable light level transitions without flicker or performance issues.
• High output performance delivers up to 4200 lumens with a 90+ CRI and a wide 100 degree beam angle, supporting uniform illumination, reduced shadowing, and accurate color rendering in large commercial spaces such as open offices, retail areas, educational facilities, and institutional environments.
• Commercial grade construction includes a durable aluminum housing, polycarbonate lens, IC rating, air tight design, and damp location rating, providing reliable long term performance in insulated ceilings and controlled indoor environments where durability and consistency are critical.
