RED + NEAR-INFRARED LIGHT
What do 660 nm and 850 nm actually mean?
660 nm is visible red light. 850 nm is near-infrared light and is not visible to the eye. Both wavelengths appear in photobiomodulation research exploring pain, soreness and recovery-related outcomes.
The wavelength is only one part of the picture. Device output, dose, timing, placement and the complete protocol all shape the results reported in research.

660 nm
Visible red
Built into Shoulder Wrap.
Studied in human photobiomodulation research across pain, soreness and recovery-related contexts.
850 nm
Near-infrared
Built into Shoulder Wrap.
Studied alone and alongside visible red light in pain and recovery-related research.
