In the clinical Weaver light is the latest development of a new light source body, its working principle is to halogen light source as a luminous body, and the light produced by it, through the German patented technology wIRA system filter, and then significantly filtered out of the human skin easy to produce thermal effects of light, but only retain the patient can accept, and has a therapeutic value of a high energy light waves. This light wave can penetrate the human body to a depth of 7cm with relative ease, and can achieve deep treatment. VIVAL Light uses 750w of ultra-high light energy, and under the premise of energy conservation, uses the energy it carries when it penetrates the body to convert it into biological energy that human tissues are sensitive to and need. In addition the use of VIVAL Light can be effective in treating deep tissue lesions in the human body, or in delayed healing of incisions, incision infections, etc.
