Flexibility enables the LX100 to wrap the pad on virtually any part of the human body. The washable, anti-bacterial silicone material incorporates 168 high energy diodes into the pad. The second generation controller has a high/low energy setting and 3 time settings. Apart from its noticeable soothing warmth, the LED lights stimulates the production of nitric oxide (N.O.) in the body. N.O. promotes circulation. As a consequence, the supply of oxygen and nutrients to the muscle is improved, and pain transmission is reduced. The LX1000 are extremely safe and easy to use. The LEDs have the same ability to reduce pain as low level lasers, but at fraction of the cost and with no side effects.
