In 1989 Dr. Ott founded OttLite Technologies to bring the power of natural daylight indoors through his one-of-a-kind natural daylight bulb. A photobiologist and pioneer in natural light research, Dr. Ott discovered through 40 years of scientific research the remarkable effects specific wavelengths of light have on all living things. Known as the father of full-spectrum lighting, his research concluded that, a light, with the entire visible spectrum of light wavelengths, was best for vision and well-being. This led to the development of the first sunlight lamp. Today, OttLite proudly utilizes our exclusive ClearSun LED technology in many of our lamps, to bring you illumination like no other. Closer to the spectral output of the sun than any other light available.
