Features: 1. Benefits for the body: Many professional doctors also use infrared light therapy for the body, achieving excellent results. Red light is known as the "light of life." 850nm near-infrared light (invisible light) penetrates deep into tissue cells, helping to alleviate pain, boost blood circulation, reduce inflammation, relieve joint pain, and ease muscle soreness. 660nm red light (visible light) acts on the epidermis, promoting healing after sports injuries. 2. Upgraded Wireless Design: Unlike traditional knee braces, this red light therapy knee brace features a power controller with a built-in 3000mAh rechargeable battery. Say goodbye to charging cables—wear it anytime, anywhere for a comfortable experience. With a large capacity built-in battery, it delivers 2–5 hours of average use per full charge, depending on the level you are using. 3. User-Friendly Operation: The red light therapy for knee features simple touchscreen controls: long-press the power button to turn it on/off, and short-press to adjust power levels and timer settings. It has three power levels (P1-P3) for adjustable intensity and offers three modes: constant light (red light + near-infrared light) and two pulse modes (10Hz, 40Hz). Pulse modes deliver energy to target pain points for deep penetration, discomfort relief, and body energy recovery. 4. Multi-Functional: This infrared knee therapy device comes with two adjustable straps of different lengths, making it easy to use on knees, elbows, or shoulders. The extra straps ensure a more contoured fit, delivering more soothing relief to the areas that need it most. 5. Lightweight and Portable: The red light therapy knee pad is made with soft, skin-friendly materials for comfortable wear. This compact red light knee therapy device features a detachable battery controller with a control panel that includes 10/20/30-minute timers and a battery indicator light, making it easy to use and manage your therapy sessions for a hassle-free experience. 6. Usage Experience: We recommend using the red light therapy pad for 20 minutes daily. During your first use, you may feel localized comfort and mild pain relief. Consistent use for 4+ weeks will leave you feeling more relaxed and relieved. Note: Clothing color and thickness may cause partial light obstruction, reducing the effectiveness of the red light therapy. Effectiveness in descending order: direct skin contact > thin white cloth > thin transparent cloth of other colors. 7. A Perfect Gift: This red light therapy for knee makes a practical and thoughtful gift for parents, family, friends, colleagues, or elders. It’s an ideal present for birthdays, holiday seasons (think Thanksgiving, Christmas), anniversaries, Mother’s Day, Father’s Day, Valentine’s Day, New Year’s, and more. Bring a smile to your parents, grandparents, friends, yourself, or your loved ones. This red light heated knee brace is a versatile gift for both men and women. 8. Manual and Accessories: infrared knee therapy set includes: 1 piece red light therapy knee pad, 2 pieces extension belt (7.87" and 22.44"), 1 piece controller, 1 piece USB charging cable (39.4"), 1 piece packaging box, and 1 piece user manual.
