If you are looking for a high-quality red light therapy device, I personally use and highly recommend 660nm&850nm Combo Bodylight.
Most red light therapy devices use only 2 watt or 3 watt LEDs, whereas our 660nm&850nm Combo Bodylight uses 5 watt LEDs for the best results. You will experience higher irradiance for better results in less time. I love that it comes in different sizes for your convenience. It’s affordable yet effective. I recommend that you try it.
