The Lightolier SD9RSLMZ10SCTUW is a versatile 9-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 SD9RSLMZ10SCTUW features Dual Select technology, allowing the installer to choose between 900 or 1200 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 provides energy-efficient integrated LED illumination with high 90 CRI, helping furnishings, finishes, merchandise and interior spaces appear natural and accurately colored.
Unlike the standard 120V version, the SD9RSLMZ10SCTUW features universal voltage and 0-10V dimming, making it especially useful for commercial, multifamily and hospitality projects requiring commercial-grade dimming controls.
The surface-mount design installs to a compatible junction box and eliminates the need for a conventional recessed housing. Its shallow profile makes it an excellent problem-solving downlight for remodeling, new construction and replacement lighting applications.

DUAL SELECT LUMEN OUTPUT
The SD9RSLMZ10SCTUW allows the installer to select between two light-output levels:
900 Lumens – Lower Output Setting
1200 Lumens – Higher Output Setting
The selectable lumen feature allows one fixture to cover multiple lighting requirements. This flexibility can help contractors, property managers and distributors reduce the number of different fixtures they need to purchase and stock.
The higher-output setting provides substantial illumination for larger spaces, while the lower-output setting is useful where a softer light level is desired.
5 SELECTABLE COLOR TEMPERATURES
The SD9RSLMZ10SCTUW provides five field-selectable color temperatures:
2700K – Soft / Warm White – Warm, comfortable illumination ideal for bedrooms, living areas, restaurants and hospitality applications.
3000K – Warm White – Clean warm illumination commonly used throughout homes, apartments, hotels and residential spaces.
3500K – Neutral White – Balanced illumination suitable for both residential and commercial environments.
4000K – Cool / Neutral White – Crisp illumination popular in kitchens, offices, work areas and commercial spaces.
5000K – Daylight – Bright white daylight appearance for applications where cooler, more energetic illumination is preferred.
The selectable CCT feature allows contractors, property managers and homeowners to choose the desired light appearance during installation instead of stocking separate fixtures for each color temperature.
SURFACE-MOUNT DESIGN
The SD9RSLMZ10SCTUW provides the appearance of a recessed downlight without requiring a traditional recessed can.
Its surface-mount design installs to a compatible junction box, making it especially useful in locations where conventional recessed housings are difficult or impractical to install.
The low-profile design creates a clean, contemporary appearance while minimizing the amount the fixture projects below the ceiling.
WIDE LIGHT DISTRIBUTION
The SD9RSLMZ10SCTUW provides an approximately 106° beam angle, producing broad, even illumination throughout the space.
The wide distribution makes the fixture particularly effective for general lighting applications where smooth, uniform coverage is desired.
