This special hand-held tool emits ultraviolet light, calibrated precisely at 370 nanometers through a focused diode tip. UV light is used in Esogetic Colorpuncture to address the information “background” of pain and ill health. It assists the flow of spirit information in the body. Note: unlike other, less expensive, UV tools currently on the market that often use plastic diodes and poorer quality parts, the Perlux UV-370 uses a high-quality glass diode embedded in a special metal socket. This guarantees the “stability” or reliability of the UV frequency in your treatments. Cost is $720 plus shipping.
