The two wavelengths
The Band, Belt, Mat and Panel run two wavelengths together: 660nm red and 850nm near-infrared. Those numbers appear on each of their product pages because they are the closest thing to a constant across the four. Here is what they mean, and what we do not claim about them.
660nm red
660 nanometres sits in the visible red part of the spectrum. It is the wavelength that produces the soft red glow you see in product photographs. It is widely used in red-light devices across the category.
We state that the Band, Belt, Mat and Panel emit 660nm red light. We do not state what that light does inside the body. That is a clinical claim, and our devices are general wellness products, not medical devices.
850nm near-infrared
850 nanometres sits just past the visible red range. The human eye cannot see it, so the 850nm output produces no visible glow. The red you see on an active Band, Belt, Mat or Panel comes from the 660nm light alone.
Like 660nm, 850nm is a standard wavelength across red-light devices. We include it in those four devices because it is part of the familiar pair. We do not describe penetration depth, cellular effects, or tissue response. Those claims belong to medical or clinical contexts, and this is not one.
Why both, in four devices
We sell six formats: Band, Cap, Belt, Panel, Mat, and Desk Bundle. Each one is shaped for a different use, and none of them is the upgraded model with the better LEDs. The same two wavelengths run in the Band, the Belt, the Mat and the Panel.
The Cap is the one device we sell without a wavelength claim. It is an infrared hair-care cap, and no wavelength is stated for it, so we print none: its spec row reads Pending sample verification until we confirm a figure on a production sample. The Desk Bundle pairs the Cap with the Band, so one of its two devices runs both.
The differences between devices are format, coverage, and where you wear them. The Band wraps a knee, lower back, shoulder, elbow, or neck. The Cap fits the head. The Mat is for lying on. Those are practical differences, not wavelength differences.
Ten to twenty minutes
Every device is built around the same session length: ten to twenty minutes. The exact time depends on what feels sustainable in your routine. The built-in timer keeps the session inside that window.
We do not promise results in a specific number of sessions. What we say is that consistency matters more than any single long session, and the ten-to-twenty-minute window is designed to survive a normal week.
What we do not claim
We do not say these devices treat, cure, or prevent any condition. We do not say they match the output of clinic-grade machines. We do not cite studies that did not test our units.
What we do say is simpler: 660nm red and 850nm near-infrared in the Band, Belt, Mat and Panel, ten to twenty minutes, in a format that fits the routine you already have.
