- Synchronize ON/OFF Timing and Dimming Controls: This feature meets efficacy requirements and ensures consistent dimming levels across multiple luminaires and individual luminaires that require multiple drivers. - True 1% Dimming: Architectural LED drivers support 1% dimming across the entire driver programmable output current range for True 1% dimming. - DIM-to-OFF: DIM-to-OFF enables luminaires to smoothly transition from DIM-to-OFF and save energy without needing additional control equipment to turn off the fixture. - Dimming Interface Protection: The dimming circuit in an OPTOTRONIC linear driver have protection against AC line voltage (120-277Vac) in the event that the driver is mis-wiring during field installation. - Constant Lumen Maintenance: The Constant Lumen Maintenance feature of the OTi 85W helps to maintain the required lumen output of the fixture at a constant level throughout its lifetime
