Technology Principles and Wavelength Properties
NIR LED effects vary significantly by wavelength. 630nm (red): 1-2mm penetration, optimal for collagen synthesis/skin regeneration. 660nm (red): 2-5mm, effective for wound healing/anti-inflammation. 810nm (NIR): 3-4cm, suitable for neural tissue/brain health. 850nm (NIR): 4-5cm, ideal for muscle/joint/deep tissue care. 940nm (NIR): 5cm+, reaches deep tissue but increased water absorption. The CIRIUS 660nm+850nm combination covers superficial to deep tissues simultaneously—the most versatile configuration.

Proper Usage Methods
Step-by-step guide for NIR LED wavelength comparison guide: Step 1—Preparation: cleanse the target area, remove metallic jewelry. Direct skin contact is most effective. Step 2—Settings: select appropriate mode (pain: 15-20 min, skin care: 10-15 min, general wellness: 10 min). Step 3—Application: position device 0-5cm from skin, maintain sufficient time per area. Step 4—After care: clean device, apply moisturizer to treated area for enhanced effects. Use 1-2x daily, 5-7 days weekly.

Area-Specific Protocols
Optimized protocols for NIR LED wavelength comparison guide: Face/skin—660nm focus, 3-6 J/cm², 10 min, 2-3cm distance, 5x/week. Neck/shoulders—850nm focus, 8-12 J/cm², 15 min, contact, 5x/week. Knees/joints—dual 660+850nm, 10-15 J/cm², 15-20 min, contact, 3-5x/week. Lower back—850nm focus, 12-16 J/cm², 20 min, contact, 3-5x/week. Fluence (J/cm²) = power density (mW/cm²) × time (seconds) ÷ 1000. Start with minimum fluence and increase gradually.

Device Care and Maintenance
Maintain CIRIUS device performance: wipe LED surface with soft cloth after each use to remove sebum/dust. Avoid alcohol-based cleaners that can damage LED lenses—use water or mild soap. Store away from direct sunlight and humidity in the provided pouch. LED lifespan exceeds 50,000 hours—approximately 4,000 days (11+ years) at 20 min/day usage. Contact customer service for output testing if performance degradation is suspected.
