Red Light Therapy Integration
660nm red + 850nm near-infrared — why 2–6 inch proximity decides everything
Red light therapy only works within 2–6 inches of skin. Beyond that, intensity drops up to 95%. Most sauna companies mount LED strips on walls 24+ inches away — ambient glow, not therapy. SaunaCloud embeds medical-grade 660nm red + 850nm near-infrared panels directly in the bench and backrest, keeping every wavelength in therapeutic range while seated, controllable independently via WiFi (cool/quiet red-only mode or combined with far-infrared heat).[1][2]
Bench-embedded vs wall-mounted
| Approach | Distance seated | Dose | Example |
|---|---|---|---|
| Bench/backrest embedded | 2–6 in. | Therapeutic | SaunaCloud Atlas/Sierra/Atlas One |
| Dual front+back factory panels | ~6–18 in. | Good (prefab best) | Sun Home Eclipse 2 |
| Wall LED strips | 24 in.+ | Ambient only | Budget brands |
| Tower (movable) | Variable | Spot treatment | Clearlight tower |
How to use
Run red-only for skin/collagen, muscle recovery and sleep support without heat; combine with 135–145°F far-infrared for circulation, sweat and relaxation synergy. Typical red sessions 10–20 min; sauna sessions 20–35 min.[1] This wiki does not give medical advice — see benefits + disclaimer.
