Peak Saunas Red Light Therapy Panel

Medical-grade photobiomodulation, engineered into every full-spectrum sauna. Here's exactly what's inside — and why it matters.

Irradiance	175mW/cm² at 6 inches — medical-grade output
Chip type	Dual-chip (each LED emits two wavelengths simultaneously for deeper tissue penetration)
Coverage	Full-body — front-facing panel covers head-to-shin while seated
Mounting position	Front wall — directly faces user while seated on bench
Control	Peak Saunas RLT App (iOS & Android) — independently controlled from sauna heat
Can be used independently	Yes — panel operates with sauna off. Use for red light therapy only without heating the cabin.

What Each Wavelength Does

Not all red light panels are equal. Most consumer panels use 1–2 wavelengths. Peak's panel uses 8 — each targeting a different tissue depth and cellular process.

Wavelength	Spectrum	Primary benefit
630nm	Red	Skin surface — collagen production, wound healing, fine lines
650nm	Red	Skin barrier function, cellular repair
660nm	Red	Peak absorption by cytochrome c oxidase — ATP (cellular energy) production
670nm	Red	Anti-inflammatory, circulation support
810nm	Near-infrared	Deeper tissue penetration — joint and muscle recovery
830nm	Near-infrared	Reduced DOMS, nerve regeneration support
850nm	Near-infrared	Deep tissue — muscle recovery, reduced inflammation deep in joints
880nm	Near-infrared	Deepest penetration — mitochondrial function in deep muscle tissue

Why 175mW/cm² Matters

Irradiance is the single most important spec in red light therapy. It's the power density hitting your skin — and it determines whether the session is actually therapeutic or just decorative.

Clinical research consistently shows the therapeutic window sits between 20–200mW/cm² at treatment distance. Peak's panel delivers 175mW/cm² at 6 inches — top of the therapeutic window — which means:

• Effective dose reached in a standard 10–20 minute session
• No need to sit uncomfortably close to the panel
• Clinically relevant dosing without guesswork

For reference: many budget panels (and several well-known $500+ standalone devices) deliver 20–60mW/cm². That's not necessarily useless, but it requires significantly longer sessions to achieve the same cumulative dose.

Using the Panel Without the Sauna Heat

The RLT panel operates completely independently from the sauna's heating system. You can run a red light therapy session with the sauna fully off — no heat, no steam, just photobiomodulation.

Good use cases for panel-only mode:

• Morning skin therapy session before getting ready
• Post-workout recovery when you don't want to heat up again
• Targeted joint treatment (knee, shoulder) without full-body heat
• Kids or elderly household members who can't tolerate sauna temps

Control is via the Peak Saunas RLT App (free, iOS & Android). The app lets you adjust wavelength combinations, intensity, and session timer independently from the SmartLife app that controls sauna temperature.

Which Peak Saunas Include This Panel

The full-spec front-facing panel (9” × 36”, 216 LEDs, 175mW/cm²) is included in all full-spectrum models:

Model	Capacity	Panels	Starting price
The Shasta	1-person	1 front-facing panel	$6,450
The Rainier	1-person	1 front-facing panel	$6,950
The Everest	2-person	1 front-facing panel	$7,450
The Fuji	2-person	1 front-facing panel	$7,950
The Patagonia	2-person outdoor	1 medical-grade panel	$9,750
The Denali	3-person	1 built-in panel	$9,250
The Matterhorn	3-person	2 panels — maximum coverage	$10,250
El Capitan & Kilimanjaro	4–5 person outdoor	1 built-in panel	$12,950+

Note: The Crown (ceiling-mounted panel, limited coverage) and Olympus/Aspen (FAR infrared only, no RLT) are exceptions. If you have questions about a specific model, contact us at sales@peaksaunas.com.

Combined Session vs. Panel Alone — What the Research Says

Running both simultaneously — infrared heat + red light therapy — creates a compounding effect that neither therapy achieves alone:

• Vasodilation from heat increases blood flow to surface tissue, enhancing red light delivery at the cellular level
• Photobiomodulation + heat together produce greater reductions in post-exercise DOMS than either alone (emerging research from combined modality studies)
• Core temperature increase during infrared heat amplifies the mitochondrial response to near-infrared wavelengths

Bottom line: if you own a standalone red light panel and a separate sauna, you're getting two separate therapies. A Peak Sauna delivers both simultaneously — and the synergy is meaningful.
