Facts of Light -
Facts of Light
By Sally Eauclaire Osborne
“Light is like food. The wrong kind can make us ill and the right kind can keep us healthy.” In our Spring issue we reviewed some of the research behind this simple, common-sense prescription from pioneer photobiologist John Nash Ott.In this issue, we’ll sift through the often conflicting information on the many full-spectrum lights available, all of whose manufacturers promise us health and happiness with a mere flick of the light switch.
Full-Spectrum Fluorescent TubesThose who go to their local store in search of full-spectrum fluorescent lights usually come home with the Vita-Lite™ brand. Though Dr. Ott invented it years ago, he no longer endorses it. Instead, he has been associated with two companies that produce higher quality, more expensive brands: OTTbioLIGHTSYSTEMS of Santa Barbara, California that sells bioLIGHTs™, and Environmental Lighting Concepts of Tampa, Florida that sells Ott-Lites™. Though the two Ott-named companies are now rivals, their products are similar and differ from Vita-Lites™ in two key ways: in the number and quality of their phosphors and in the use of lead shielding on the ends of the tubes.
