This combination set includes both the light pen which emits infrared light, calibrated at precisely 950 nanometers and the light pen which emits ultraviolet light, calibrated precisely at 370 nanometers. These frequencies are transmitted through focused diode tips. The IR light is used particularly in the Esogetic system for treatment of pain. The 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. This combination set also offers a savings when compared to the purchase of the separate IR and UV penlight sets. Note: unlike other less expensive IR and UV tools currently on the market that often use plastic diodes and poorer quality parts, the Perlux IR-950 and Perlux UV-370 use high-quality glass diodes embedded in a special metal socket. This guarantees the “stability” or reliability of the IR or UV frequency in your treatments. Price is $1126.00 plus shipping. .Please call for a consultation in order to purchase this product.
