health of animals, humans, and individual cells, using time-lapse micro-photography. Ott's experiments led him to believe that only a full spectrum of natural light (including natural amounts of infrared and ultraviolet) could promote full health in plants, animals, and humans. He wrote a 1973 book entitled Health and Light advancing his theories. Such topics were also addressed in his 1974 film Exploring the Spectrum. Ott received an honorary doctorate in science from Loyola University of Chicago in 1958. Although it is not customary for recipients of such an honorary doctorate to adopt the prefix "Dr.", he was widely referred to as "Dr. Ott" thereafter. Natural lighting products Ott believed that the proprietary lighting technology he developed was the closest replication to the sun's natural wavelengths. He developed several consumer products based on this technology, including altered lightbulbs and a special pair of polarized sunglasses which he believed would enhance the physical and mental fortitude of anyone wearing them. In 1989, entrepreneur Fred Mendelsohn started Environmental Lighting Technologies (doing business as Ott-lite Technologies) and worked with Ott to develop the technology into award-winning products for businesses and homes. OttLite describes its "508 technology" as providing a balance of brightness and contrast that reduces glare and eyestrain and produces very low heat. The products, called "High Definition Natural Lighting", are marketed online and at lighting, crafting, and hardware stores.
