About this device
Six feet of red light. 1280 diodes at 660 nm red and 850 nm near-infrared across a 71 by 31 inch flexible mat, so you lie down once and treat back, hips, hamstrings and calves in a single session instead of moving a small panel around your body for an hour.
This is the format the clinics use and the one the branded names charge four figures for. Same wavelengths, same coverage, published numbers, and a timer so you cannot overdose the session.
If you buy one light device for your body rather than your face, this is it.
