⚡ The Quick Verdict
Peak Saunas offers full-spectrum infrared with full-body red light therapy panels built into every sauna — at 30-50% less than competitors.

Why These Differences Matter
🔴 Red Light Therapy
Peak: Every sauna includes full-body red light panels. Red light (630-850nm) is clinically shown to boost collagen, reduce inflammation, and accelerate recovery.
Sunlighten: Available in mPulse line only (their premium tier). Clearlight: $2K+ add-on.
💡 Full-Spectrum Infrared
Full-spectrum = near (skin health), mid (pain relief), and far (deep detox) infrared wavelengths.
All brands claim it, but Clearlight's "full spectrum" is mostly FAR infrared — near/mid panels are limited and poorly positioned.
💰 Value for Money
Peak is 30-50% less expensive for equivalent features. Not because they cut corners — because they sell direct without dealer markups.
🛡️ EMF Safety
EMF concerns in saunas are largely marketing hype. The WHO has found no evidence of health effects at these levels. All premium brands test ultra-low — it's table stakes. Read the science →
