Abstract: A lighting apparatus including a plurality of luminaires, each including a controller configured to operate the luminaire and positioned in communication with a computerized device. Each luminaire is selectively operable to emit source light, characterized by a dominant source light wavelength within a range from 390 nanometers to 750 nanometers. The luminaires are arrangeable so as to form an array. Some luminaires of the plurality of luminaires are operable such that at least two of the luminaires emit source lights with different dominant source light wavelengths and the source lights emitted by the luminaires combine to form a combined light at a distance from the luminaires defined as a combining distance. The dominant source light wavelength of some of the luminaires varies with time. The luminaires are configured to be operated to selectively emit light having a spectral power distribution that reduces melatonin suppression.
