As full-spectrum light technology and SAD light therapy pioneers (Ott Light Systems 1987-97) and now Science of Light (SOL), a 501(c)(3) nonprofit organization, we’ve been on a mission to raise awareness of “mal-illumination” and the vital need for a “balanced spectral diet” to enhance body-mind wellness and reduce the risk of disease.

“Mal-illumination is to light as malnutrition is to food.”
