Wavelength-by-Wavelength Performance
| Wavelength | Voltage Range | Light Power | Key Applications & Benefits |
|---|---|---|---|
| 740nm | 1.8–2.2V | 400–500mW | Optimal for hair growth: Penetrates precisely to hair follicle depth, stimulates follicle metabolism and extends anagen phase; also ideal for biometric identification and vein detection |
| 850nm | 1.4–1.8V | 400–500mW | Best for deep tissue therapy: Balanced penetration depth and energy output, enhances blood circulation, accelerates tissue repair and reduces inflammation |
| 940nm | 1.2–1.6V | 300–400mW | No-red-glow infrared: Completely invisible to the human eye, provides discreet therapy without light emission; perfect for wearable devices and night vision applications |
