The Lightolier SD9R12ESCT1W is a versatile 9-inch round LED surface-mount downlight designed to provide the clean appearance of recessed lighting without requiring a traditional recessed can. Its slim, low-profile design makes it an excellent solution for residential, multifamily, hospitality and light-commercial applications, especially where ceiling space is limited.
The SD9R12ESCT1W delivers approximately 1200 lumens while consuming approximately 16 watts, providing bright, energy-efficient LED illumination for kitchens, living rooms, hallways, bedrooms, offices, apartments and other interior spaces.
The fixture features five field-selectable color temperatures: 2700K, 3000K, 3500K, 4000K or 5000K. This allows the installer to select the desired light appearance during installation without purchasing separate fixtures for different color temperatures.
High 90 CRI provides excellent color rendering so furnishings, finishes, countertops, flooring and interior spaces appear natural and accurately colored.
The SD9R12ESCT1W operates on 120V and features TRIAC / phase-cut dimming, making it particularly well suited for residential and other 120V applications using compatible wall dimmers.
Unlike the SD9RSLMZ10SCTUW Dual Select commercial model, the SD9R12ESCT1W has a fixed 1200-lumen output. The color temperature remains field selectable, but the lumen output is not selectable.
The surface-mount design installs to a compatible junction box and eliminates the need for a conventional recessed housing, making it an excellent problem-solving fixture for remodeling, new construction and replacement lighting applications.

1200 LUMEN OUTPUT
The SD9R12ESCT1W provides approximately 1200 lumens of bright, efficient illumination.
Unlike the SD9RSLMZ10SCTUW Dual Select model, the SD9R12ESCT1W does not have selectable lumen output.
Its output is fixed at approximately 1200 lumens, making it a straightforward choice for applications where a consistent higher light level is desired.
The 9-inch size and 1200-lumen output make the fixture particularly useful for larger rooms and areas where more illumination is desired than smaller 5-inch or 7-inch surface-mount downlights typically provide.
5 SELECTABLE COLOR TEMPERATURES
The fixture provides five field-selectable color temperatures:
2700K – Soft / Warm White
Warm, comfortable illumination ideal for bedrooms, living rooms, restaurants, hospitality areas and other relaxing environments.
3000K – Warm White
Clean warm illumination commonly used throughout homes, apartments, hotels and residential interiors.
3500K – Neutral White
Balanced illumination suitable for residential and light-commercial environments.
4000K – Cool / Neutral White
Crisp illumination popular in kitchens, offices, work areas and commercial spaces.
5000K – Daylight
Bright daylight-white illumination for applications where a cooler and more energetic light appearance is preferred.
The desired CCT can be selected during installation, allowing one fixture to accommodate multiple rooms and applications.
120V TRIAC DIMMING
The SD9R12ESCT1W operates on 120V and is designed for use with compatible TRIAC / phase-cut dimming controls.
This makes it especially convenient for residential installations where traditional wall-box LED dimmers are commonly used.
This is an important distinction from the similar SD9RSLMZ10SCTUW, which is designed for universal-voltage commercial applications and uses 0-10V dimming.
SURFACE-MOUNT DESIGN
The SD9R12ESCT1W provides the appearance of a recessed downlight without requiring a traditional recessed housing.
Its low-profile surface-mount design makes it particularly useful in locations where conventional recessed cans are difficult or impractical to install.
The fixture mounts to a compatible junction box, providing a clean, contemporary appearance while minimizing how far the fixture extends below the ceiling.
