The Lightolier by Signify SD5RSLMZ10SCTUW is a versatile 5-inch round LED surface-mount downlight featuring both field-selectable lumen output and field-selectable color temperature. Its slim, low-profile design provides the clean appearance of recessed lighting without requiring a traditional recessed can, making it an excellent solution for challenging ceilings and applications with limited plenum space.
The SD5RSLMZ10SCTUW features Dual Select technology, allowing the installer to choose between 540 or 700 lumens as well as five color temperatures: 2700K, 3000K, 3500K, 4000K or 5000K. This flexibility allows a single fixture to accommodate a wide variety of residential, multifamily, hospitality and commercial lighting applications.
The fixture operates at approximately 9 watts at 540 lumens or 11 watts at 700 lumens, providing energy-efficient LED illumination. High 90 CRI delivers excellent color rendering so furnishings, finishes and interior spaces appear natural and accurately colored.
Unlike the standard 120V TRIAC version, the SD5RSLMZ10SCTUW features universal voltage and 0-10V dimming, making it especially useful for commercial and multifamily projects that require commercial-grade dimming controls.
The surface-mount design installs to a compatible junction box and eliminates the need for a conventional recessed housing. The fixture's extremely slim profile makes it an excellent problem-solving downlight for remodeling, new construction and replacement lighting applications.
