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.

randomized trials have tested red and near-infrared light together, according to a 2026 systematic review.
660 + 850 nm is one of the most common pairings in that research. The NOVA Neck, Precision Cap, Knee Device and Hand Glove all use it.research areas list 660 nm as a main or frequently used wavelength, more than any other.
Including skin, hair, wound healing, joints and muscle recovery.head-to-head studies found pulsed light did better than continuous light.
Hashmi et al., 2010 review. Studies most often pulse at 10–100 Hz, well inside the NOVA Neck’s 1–1,000 Hz range.How much research sits behind each wavelength in each area, from the core range to the ones used less often.
Each part of the body sits at a different depth, so each calls for different wavelengths. Pick an area to see the wavelengths studied for it and the RedLife devices that deliver them.
That combination reaches across the most areas in the research. Every thyroid bundle starts with the NOVA Neck at 660 + 850 nm. The Core and Complete bundles add Pro panels with all 10 wavelengths, including 810 nm.
