The Lightolier 3-Inch LED Round Downlight (DL23RSLMZ10SCTUW) is a versatile, high-performance fixture engineered for commercial and residential installations that demand flexibility. With selectable wattage of 4.2W or 6W and corresponding output of 500 or 700 lumens, you can optimize energy use and light levels to suit the application — all from a single SKU. Universal voltage operation (120–277V) simplifies specification across a wide range of electrical systems, while 0–10V dimming provides smooth, precise control down to low levels.
This 3-inch downlight supports five selectable color temperatures — 2700K, 3000K, 3500K, 4000K, and 5000K — with a 90 CRI rating and a 107° beam angle for broad, even illumination. The matte white finish and baffle trim deliver a clean, commercial-grade aesthetic. Constructed with a die-cast aluminum flange and extruded aluminum steel junction box, the fixture is built for long-term reliability, rated L70 at 50,000 hours and backed by a 5-year warranty.
Installation is made easy with a locking power connection (14.96 in / 38 cm lead), quick connectors, and an included foam gasket. The fixture is IC-rated for direct contact with thermal insulation and features AirSeal construction for minimal air leakage. It is ETL listed (UL 1598) for damp locations, ENERGY STAR® certified, Title 24 (JA8) compliant, and RoHS compliant. Operating temperature range is -30°C to 40°C.
