The research behind the wavelengths

660 nm is the most-studied wavelength in red light research.

Each bar counts the PubMed papers that name that exact wavelength alongside photobiomodulation, red light therapy or low-level laser therapy. The NOVA Neck in every thyroid bundle uses 660 nm and 850 nm. Tap a wavelength for details.
