3 Wavelength Infrared Light TherapyThe red light therapy consists of red light at 660nm, near-infrared light at 850nm, and far-infrared light at 940nm. This gentle and safe therapy relies on the thermal effect to raise the internal temperature, rather than traditional radiation heating lamps. The longer the wavelength, the deeper the reach and the better the effect. The scientific combination of these 3 wavelengths ensures an enhanced usage experience. 940nm Upgraded Red Light TherapyThe red light lamp with a bracket is designed with 4 heads and equipped with 180 high-quality LED beads, including 180 660nm chips, 180 850nm chips, and 180 940nm chips. The power output is up to 32W, and the 940nm far-infrared light reaches deeper, allowing for a more deep red light therapy experience. Adjustable Height & Brightness & AngleThis red light therapy lamp comes with a stand that offers an adjustable height range of 15-60 inches and 4 modes (1 head to 4 heads). The gooseneck tube allows for easy angle adjustment to achieve optimal comfort and desired light intensity. For stable operation, it is recommended to use the device with the bottom 3-legged stand kept flat. Distance and Frequency of UseThe installation and adjustment of the infrared light therapy for body are effortless, making it convenient for home or office use. Position the red light 5-10 inches away from your body. We recommend using it for 15-30 minutes per session, 3-4 times per week for 4-5 weeks. Please be patient and allow the red light to bring about positive changes.
