The Perlux Combi Deluxe lightpen set 

It includes two light pens, one set of 7 color flat focal and 7 handcrafted straight glass rods with pyramid cut for in RED, ORANGE, YELLOW, GREEN, TURQUOISE, BLUE and VIOLET.

These 7 rainbow colors are divided into warm colors (RED, ORANGE, YELLOW) to enhance energy; and cold colors (GREEN, TURQUOISE, BLUE and VIOLET) to detoxify, relax and cure pain.  Treatment by color can be performed on finger meridians, on chakras, painting the certain points by the certain color following the laws of colors interaction (and consequently, energies) and thus changing the energy potential (balance) both in the point, and in all meridian, and, hence, in organ.  

It is for:
1. treatment of zones and bigger areas on the skin.
2. infusing color directly into the body via the acupuncture and other energy points on the skin.

These light and color treatments involve the application of colored light on the skin with an instrument that resembles a simple pen light from the set. In spite of its name it does not use needles or pierce the skin. Rather the color sensitivity of acupuncture receptors on the skin is used. Acupuncture meridians, among others, then channel healing information encoded in the light to targeted cells and dysfunctional organs where it is needed.

"Color," says Mandel, "is life energy carrying information.... The information heals and the energy carries that information through the cells." The method is based also on the photon light research of renowned biophysicist Dr Fritz Popp, who uncovered the photon (light particle) communication between the cells.
