Abstract: A dual output downlight luminaire includes a housing that forms at least a first cavity. A partition extends from a portion of the housing and at least partially forms a boundary between the first cavity and an annular second cavity. A first light source emits a first light that is centered about an optical axis and propagates toward a first output aperture. An optic redirects the first light to form a first light beam that exits the luminaire through the first output aperture. A concentrated portion of the first light beam subtends an angle of 60 degrees or less and is centered about the optical axis. A plurality of second light sources, within the second cavity, emit a second light that exits the luminaire through an annular second output aperture. The first and second light sources are independently controllable with respect to each other.
