Abstract
A method and system may include commanding, by a processor, a lighting system to generate a desired melanopic effect in accordance with a spectral weighting mode. To determine, by the processor, the spectral weighting mode based on an algorithm that compares a part of a spectrum for an amount of melanopic lumen to a melanopic sensitivity curve to generate a result comprising a melanopic ratio. In response to the result comprising the melanopic ratio, to by determine by the processor a visual brightness by calculations using an algorithmic solution based on the melanopic ratio multiplied by an amount of color temperature generating the visual brightness in accordance with the spectral weighting mode of the desired melanopic effect.
