<p><b>Why combine 630nm 660nm and 850nm?</b></p> <p> </p> <p>630nm:660nm:850nm=1:1:1</p> <p> </p> <p>The near infrared 850nm wavelength is actually outside of the visual spectrum, so it may appear as if the NIR lights are not working, but they just can’t been seen by the naked eye. It penetrates deeply into the tissue, organs, and joints, making it ideal for enhancing muscle recovery and reducing joint pain.</p> <p> </p>
