The Lightolier 4-Inch 12-Watt LED Round Downlight (DL24R10ESCT1W) delivers exceptional performance in a compact, low-profile form factor designed for both commercial and residential applications. Operating at 120V and producing 1,000 lumens with a wide 108° beam angle, this fixture offers selectable color temperatures — 2700K, 3000K, 3500K, 4000K, and 5000K — giving you the flexibility to dial in the perfect ambiance for any space. With a 90 CRI rating, colors appear vivid and true-to-life under its light.
Built to last, the downlight features a die-cast aluminum flange and extruded aluminum steel junction box, finished in a clean matte white. It is rated L70 at 50,000 hours and backed by a 5-year warranty, making it a reliable long-term investment. The fixture is IC-rated for direct contact with thermal insulation and includes an AirSeal design for minimal air leakage — ideal for energy-conscious installations. TRIAC dimming to 5% is supported, compatible with standard ELV/TRIAC 120V dimmers.
Installation is straightforward thanks to a locking power connection between the junction box and fixture (standard 14.96 in / 38 cm lead), quick connectors, and a foam gasket included in the box. The fixture is ETL listed (UL 1598) for damp locations, ENERGY STAR® certified, Title 24 (JA8) compliant, and RoHS compliant, meeting the most demanding commercial project specifications. Operating temperature range is -30°C to 40°C.
