Dr. Ott The Original

Dr. John Nash Ott started it all! In 1989 Dr. Ott founded OttLite 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, we are proud to continue Dr. Ott’s legacy. He believed that by seeing better and feeling better, people could do what they love longer. And we believe that getting to do what you love—whether it’s reading, writing, sewing, knitting, drawing, or growing magical pumpkins—is what life is really all about.

See how we continue to bring Dr. Ott's work to life through innovative natural daylight OttLite lamps.

A Fairy Tale Beginning ...

Have you ever seen those Disney movies with all the beautiful flowers opening and dancing – growing from seed to full bloom before your eyes? Then you’ve seen the work of Dr. John Nash Ott. Dr. Ott is known as the father of time lapse photography. In fact, he was asked by the Walt Disney Company to film the entire growth of a pumpkin for Disney animators to draw the transformation of Cinderella’s pumpkin into a carriage. 

Filming had to take place indoors to protect the extensive camera equipment. At first the plant would grow and then die. Dr. Ott tried several things, but nothing would work. Then he changed the lighting. What he found was that under some lighting conditions, only male pumpkin flowers grew, but no females. The lights were adjusted and then only females were produced, but no males. After several experiments, Dr. Ott was able to provide the proper range of light wavelengths and the pumpkin grew.

Not only did he help Cinderella arrive at the ball, but this remarkable work sparked his imagination leading him to explore the benefits of natural daylight and how it can help people see and feel better. Learn more about OttLite's healthy lighting
