Through 40 years of research, photobiologist Dr. John nash OTT, a world renowned scientist and pioneer in time lapse photography, has developed a variety of truecolor lighting products. Dr. Ott met the challenge of reproducing natural daylight indoors when he developed the first ott-lite while filming the secrets of life series for walt disney. this new technology has revolutionized the way we view everything. for the first time, it is possible to see indoors as clearly as we do outside under natural daylight; without the heat, glare, and distortion of ordinary artifical lighting. special formulated rare earth phosphors are used to create illumination that accurately creates natural daylight indoors. these formulations are custom blended to produce light that satisfies specific viewing requirements such as lower glare, less distortion, better detail definition, and accurate colour rendering.
