Abstract
A lighting system with selectable emission characteristics may include a housing, a controller, a first plurality of light sources operatively coupled to the controller and carried by the housing, and a second plurality of light sources operatively coupled to and controlled by the controller and carried by the housing. The first and second pluralities of light sources may be operable to emit first and second combined lights, respectively, and to emit a first light having a wavelength within the range of 650 nanometers to 700 nanometers, a second light having a wavelength within the range of 500 nanometers to 570 nanometers, and a third light having a wavelength within the range of 430 nanometers to 470 nanometer. The second light may be characterized by a human photopic response of greater than 0.0 and less than 0.4 throughout the range from 500 nanometers to 570 nanometers.
