A Deeper Look at Light & Heat
Color for Mood and Balance
Chromotherapy uses visible colored LED lights to influence mood and relaxation. It’s about how you feel, not how deep the light penetrates.
Think of it as ambiance therapy, not cellular therapy.
Deep Heat You Can Feel
Far Infrared light is invisible - you won’t see it, but you’ll feel it. It warms your body directly for deep detoxification, improved circulation, and relaxation.
That soothing warmth is the infrared at work — not the red light.
Complete Infrared Coverage
Full Spectrum means all three wavelengths:
- Near Infrared: Skin repair & surface healing
- Mid Infrared: Muscle and tissue recovery
- Far Infrared: Deep detox and relaxation
Our Tosi models include Near Infrared LED Kits, which produce a soft red glow - a mix of visible and invisible wavelengths for total-body coverage.
True Full Spectrum light works beyond what your eyes can see.
Cellular-Level Energy
Red Light Therapy uses precise, low-level light (630–850nm) to boost your cells’ natural energy and repair processes.
No sweat, no heat - just pure light rejuvenation.
Supports collagen, recovery, and cellular health.

“If It Glows Red, Is It Red Light Therapy?”
Not always. Many saunas use red-colored bulbs for chromotherapy or ambiance.
True Red Light Therapy requires precise light wavelengths - the same ones built into JNH’s Arki Dual Therapy™ System, combining red and near-infrared light at 630 - 850nm for real, measurable cellular benefits.
