The exact spectrum ranges from some red light (660nm) and to the limit of infrared light (880nm), with peak output wavelengths designed to coincide exactly with our peak absorption in this range. The emitted light is focused by a lens into a penetrative point, meaning the light can be effectively used worn next to the skin. The low-power design allows the device to generate comfortable heat and will not burn the skin.
Just need a simple connection to enjoy life. 110V-240V wide voltage design is suitable for voltage standards of most countries in the world. Place on body and secure straps.Plug into a electrical outlet. Press on/off switch to activate device. You can only see the red LED's; the others are in the Infrared light spectrum and can't be seen with our eyes. Auto-off time is 20 minutes and can be used multiple times per day. Less than 3 broken lights (total 176 lights) will not influence the effect of this light therapy. It still works well when there are three or less lights off.
Please make sure your skin is cool and dry when using the lights wrap. Do not strike or step on the lights system for it may damage the lights.
Not intended use on face therapy. Use it 2-3 times a day, each time 20-40 minutes. People with heart disease or heart pacemaker can not use this light therapy system.Expectant mother, skin-ulcers and allergic people can not use it. Please be patient as it may take several weeks or longer to experience optimal relief.
Effect may be different to different people as their conditions can be varied and complex.
