45W Red Light Therapy Lamp, 660nm 850nm Dual Wavelengths For Home Use, Full Body Treatment

660nm Wavelength: Crimson 660nm is the most suitable wavelength, simulating the red wavelength of the sun, allowing you to bask in the sun at home, carry out simple training, and enjoy bright illumination anytime, anywhere. 850nm Infrared: Infrared 850nm looks dark but works fine, it penetrates deeper into the skin, increasing the penetration of light through the skin to the sore point, relieving pain more effectively, and providing essential energy for cells to renew nutrients and remove waste.
