I have been studying the use of sound and light frequency therapy for many years. Which led me to learning about the benefits of the red spectrum of light.
Years ago I bought a small hand held infra-red device at a garage sale that I used for many years on my sore muscles and joints. I think I lost it in one of my many moves in the past couple of years. Recently, I bought a infrared bulb and a special socket and wired it up in my bathroom. Infrared bulbs are not difficult to obtain and are available at many online an big box stores all over the world. They come in many different strengths you can buy just the bulb or, with a fixture. I bought the bulb and fixture separate because it was more cost effective for my particular application.
