The Wattstopper LMFI-111 is a fixture interface and power converter designed to wire directly to a fixture’s 010V LED driver for continuous dimming control within Digital Lighting Management (DLM) systems on 120277V. It supplies power to LMFS sensors while delivering a 010V output signal to compatible LED drivers, eliminating the need for a separate power supply. Intended for commercial applications including conference rooms, open offices, and other DLM-controlled environments.
