The LR23881 is an energy-efficient 4-inch LED disk light designed for versatile residential and commercial surface-mount lighting applications. Equipped with an integrated adjustable Passive Infrared (PIR) motion sensor, this fixture features bi-level dimming functionality to enhance energy savings while providing reliable safety and security lighting. Operating at just 8 watts, it produces 700 lumens of continuous illumination with a high 90 CRI for vibrant, accurate color rendering.
Engineered with 5-CCT field-selectable technology, the LR23881 allows installers to choose between 2700K, 3000K, 3500K, 4000K, and 5000K color temperatures directly on the fixture. With a wide 110º beam angle, a slim 1.10-inch profile, and a rated lifespan of 50,000 hours, this disk light provides smooth, uniform light distribution with minimal maintenance over time.
