SLTBR was founded in 1988 to study the science of and therapeutic effects of light, biological rhythms and melatonin with a program of scientific interchange, literature review and critique. SLTBR has played a key role in establishing standards for these specialized areas through consensus development, professional education, and information transfer to the public.

In July 2007, we held a highly stimulating and productive 19^th Annual Meeting in Copenhagen, Denmark. The program included symposia entitled "Light Treatment, Light at Night and Risk of Cancer" and "Light Therapy for Non-Seasonal Depression". Several world class scientists who have published in the very best journals participated in these symposia. The program also included cutting edge research by a variety of international presenters in the form of submitted papers and posters. The Annual Meeting is one example of how SLTBR fosters communication between basic scientists, clinicians applying light therapy, and consumers and manufacturers of lighting devices.

This years meeting in Vancouver from June 26-28^th promises to continue our long tradition of combining scientific excellence with camaraderie and collaboration, and we hope to see you there. A full description of the meeting and all related forms are available through the main page of this website.
