PTI Reference Library

The links below make up our Reference Library of information about all aspects of Light Therapy.


Please use these categories to search for information about Light Therapy and Photopuncture by topic. These pages may include a mix of research articles, blog posts, videos, and articles from various media outlets. General information is open to the public, more in-depth and specialized information is open to our members only.

If you do not find the information you are looking for, please JOIN as a free CANDLE member and come to our live "Office Hours" meetings every Thursday morning. There you can ask specific information of those with many years of experience with using Light to help people and animals.
