A 10-inch round LED downlight for commercial or residential recessed lighting, with field-selectable wattage and color temperature, rated for damp locations.
Nuvo Lighting's Plus Series S21603 is a versatile LED downlight designed for both new construction and remodel applications. Its regressed baffle and frosted lens reduce glare while delivering high-quality 90+ CRI illumination. The fixture is field-selectable among five color temperatures (2700K-5000K) and three wattages (24W/29W/35W), making it adaptable to various lighting needs. The white painted aluminum construction suits utility and commercial spaces.
