System for generating non-homogenous biologically-adjusted light and associated methods

A lighting apparatus comprising:

• a computerized device;
• and
• a plurality of luminaires, each luminaire comprising a controller configured to operate the luminaire and positioned in communication with the computerized device;
• wherein each luminaire is selectively operable to emit source light, each source light having a dominant source light wavelength within a range from 390 nanometers to 750 nanometers;
• wherein the plurality of luminaires are arrangable so as to form an array;
• wherein the computerized device is programmable to operate at least some luminaires of the plurality of luminaires such that at least two of the plurality of luminaires emit source lights with different dominant source light wavelengths, and such that one or more source lights emitted by the plurality of luminaires combine to form a combined light at a distance from the plurality of luminaires defined as a combining distance;
• wherein the computerized device is configurable to vary the dominant source light wavelength of at least some luminaires of the plurality of luminaires with time;
• and
• wherein the plurality of luminaires are configured to be operated to selectively emit light having a spectral power distribution that reduces melatonin suppression.
