ecSTIM Red Light Therapy Knee Brace

Red Light Therapy Knee Brace is a home health device designed for relieving knee pain and recovering after exercise. It uses advanced red and near-infrared light technology combined with 76 dual-core LEDs to provide a uniform and deep phototherapy effect. The product is lightweight and portable, weighing only 0.2kg, and is equipped with a 2000mAh high-capacity battery and wireless design, so it can be used anytime, anywhere. It is easy to use, with an automatic 10-minute shutdown and pulse and vibration functions to improve knee health and comfort. Whether you have arthritis pain or sports fatigue, this protector is an ideal choice for your daily health management.

What is red light?

Red light is a type of low-energy light with a wavelength range of typically 620–750 nm in the visible spectrum and 750–1200 nm in the near-infrared spectrum. Red light therapy uses LED technology to emit light of these specific wavelengths, which can penetrate about 8-10 mm into the skin, acting on the epidermis, hair follicles, superficial joint tissues and even the cellular level. The core mechanism is “photobiomodulation”: the light is absorbed by mitochondria in cells, stimulating the production of adenosine triphosphate (ATP) and thus enhancing cell activity. Red light is safe and does not cause thermal damage. The irradiance is usually kept between 30 and 130 mW/cm². Unlike ultraviolet light, it does not damage the skin and is therefore very suitable for home use. Red light is often combined with 660 nm red light and 850 nm near-infrared light to provide a variety of health applications.
