Abstract: Methods and systems for modulating a manufactured light source are disclosed. Methods and systems of the present disclosure include sensor assemblies having first and second light sensors to retrieve light spectrum data at a target location, such as from a surface in an interior space at a home, office, or commercial building, that also receives daylight exposure. The first light sensor retrieves the light spectrum data within a spectrum of the manufactured light source. The second light sensor retrieves light spectrum data outside of the spectrum of the manufactured light source, yet within the spectrum of daylight. The light spectrum data is used to define spectral characteristics at the target location, such as a ratio of daylight to the manufactured light source, phase of daylight, and average overall quantity, which are used to maximize light-associated benefits of the spectral composition for the occupants at the target location, such as humans, plants, and animals.
