Circadian effective luminaire

A method of promoting circadian entrainment to an area, comprising:

• providing a lighting system comprising a luminaire and a controller in electrical communication with the luminaire, the luminaire comprising:
• a frame comprising a first end, a second end opposite the first end, and an aperture at the second end;
• an ambient light source positioned within the frame adjacent the first end of the frame;
• a downlight light source positioned within the frame adjacent the second end of the frame;
• a first driver in electrical communication with the ambient light source and the controller, the first driver is configured to adjust the illuminance of the ambient light source;
• a second driver in electrical communication with the downlight light source and the controller, the second driver is configured to adjust the illuminance of the downlight light source;
• a timeclock in electrical communication with the controller;
• a diffuser connected to the frame and at least partially surrounding the ambient light source;
• and
• a reflector positioned within the aperture of the frame, the reflector configured to direct light emitted by the downlight light source;
• generating, via the timeclock, time of day data;
• communicating the time of day data to the controller;
• generating, via the controller, at least one illuminance mode control signal in response to the time of day data;
• communicating the at least one illuminance mode control signal to at least one of the first driver and the second driver;
• and
• adjusting the illuminance of at least one of the ambient light source and the downlight light source between a plurality of illuminance modes in response to the at least one illuminance mode control signal.
