1、Reduce Inflammation: Red LED can be transmitted to human epidermis, connective tissue, blood vessels and absorbed by living tissue. It can improve local tissue ischemia, reduce inflammation and swelling. 2、Reduce soreness: Our red LED therapy device can reduce pain, relieve muscle spasm, relax muscles, and promote collagen production, which is very practical. 3、Application: Our infrared therapy lamps can be used for the rehabilitation of body parts and joints such as knees, shoulders as well as the rehabilitation of pets such as cats and dogs. 4、5 Wavelengths: Our infrared red LED therapy lamp has 5 wavelengths of 620nm, 650nm, 660nm, 710nm and 850nm. It can better promote cell healing, penetrate deeper into the skin texture, and help you relieve pain. 5、Portable: Our red LED physiotherapy device is light in weight and small in size, which is easy to store and carry, and fit easily into your bag for travel use. Item Type: Red LED Therapy Device Material: Aluminum alloyBattery: Lithium battery 1200mAh (built in) Note: 850nm can not see by human eyes Application description: Light physical therapy effect, through the method of physics, it emits 620nm, 650nm, 660nm, 710nm and 850nm light wavebands (in the same waveband as the He Ne laser, deep penetration, red LED penetrates the human body and the red LED waveband optical effect (after the red color), the effect of light on the activity of mitochondrial catalase increases, enhances cell metabolism and protein synthesis, promotes local blood circulation, and controls the increase in infection. 1 x Red LED Therapy Device 1 x Lanyard 1 x Battery Charger 1 x Storage Bag
