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

Key Advantages 

High Power Density: 3W output delivers industry-leading infrared intensity for faster and more effective therapeutic results

Premium Ceramic Substrate: Provides superior heat dissipation compared to plastic packages, ensuring long lifespan and stable performance even during 24/7 operation

120° Wide Beam Angle: Ensures uniform coverage across large treatment areas, ideal for body therapy belts and full-scalp hair growth caps

Multiple Wavelength Options: Three clinically validated infrared wavelengths to suit different therapeutic requirements
