Abstract: A method for sanitizing a space includes positioning a plurality of light sources configured to emit light in a wavelength between 185 nm and 405 nm. At least one pathogen which is desired to kill in the space is determined. A contamination level of the pathogen in the space is determined with at least one sensor. A treatment plan is determined for emitting light from at least one of the plurality of light sources with a controller to eliminate the pathogen. The treatment plan includes a determination of at least one light wavelength in the range of 185 nm and 405 nm, at least one light intensity, and at least one duration of time at which to emit the light to kill the pathogen. Light is emitted in accordance with the treatment plan.
