LB4R | 4" Round Economy Super Thin Recessed LED 11W
The Lotus LB4R is a 4-inch round economy super-thin recessed LED fixture designed for recessed ceilings, showers, and soffits. With a fixture depth of only 1/2", it is built to install directly under joists and fit in tight ceiling spaces where traditional recessed fixtures may not work.
This compact 11W recessed LED offers a wide 110° beam angle, 700 to 730 lumen output depending on selected color temperature, and the efficiency of a 65W halogen equivalent. The LB4R includes a 120V AC Triac dimmable driver as standard and is available in 3000K, 4100K, and dim-to-warm 3000K to 2000K configurations.
