Feedback Loops

Feedback Loops

The Feedback Loop draws out detrimental energy and then immediately feeds it back into the body as beneficial energy.

It has a smaller diameter coil and the energy flowing through it is at a higher velocity – more like a high-pressure car wash than the Acu-Vac Coil which is compared to a garden hose. Unlike the coil, the Feedback Loop performs this energy exchange without needing to turn the tool around.

We recommend using your intuition for the best way to use our Feedback Loops. Here are some common uses:

  • Position the loop toward you to pull out discomfort from an area
  • Place a loop in a vertical position next to your bed to break up conflicting energy, restore balance and help you enjoy a good night’s sleep
  • To remove discomfort faster, hook it onto an Acu-Vac Coil to increase healing power
  • Use the Feedback Loop in combination with an Acu-Vac Coil by hooking them both onto a Light-Life Tensor Ring to create super potentized water.


  • Sacred Cubit : The Sacred Cubit Feedback Loop appears to extract discomfort, enhance sleep, stop disharmonious energy and relieve aches. Some chiropractors use it very effectively instead of lasers with the same results, but without the high upfront costs. Sacred Cubit Feedback Loops


  • Lost Cubit : The Lost Cubit Feedback Loop appears to work faster and focuses more on emotional and mental issues. Lost Cubit Feedback Loops


  • Large Lost Cubit : The Large Lost Cubit Feedback Loop has benefits similar to those of the Lost Cubit but because of its larger size, results may be faster and stronger. Originally, it was made for veterinary practitioners and ranchers for use on large animals. However, it soon became a favorite for health practitioners as the results (especially for chronic discomfort and inflammatory conditions) were much faster. Large Lost Cubit Feedback Loops


We craft our Light-Life Tools out of copper, then they are plated with silver and 24K gold. We also manufacture Light-Life Tools by request in sterling silver. In addition, subtle audio frequencies known to produce health improving effects and other beneficial qualities are embedded into all our tools as they are being made.

Copper: Copper is a metal that has, according to Slim Spurling, the ability to transmute cosmic energy into life force energy. Its natural tendency to oxidize with age gradually boosts its power.

Copper Plated with Precious Metals: Our gold-plated Light-Life Tools begin with copper, are plated with a layer of silver and a layer of 24K gold. The 24K gold plating adds a higher frequency due to the structure of its atom in the crystal as it is applied to the tools. The silver-plated Light-Life Tools begin with copper, are plated with one layer of silver and 24K gold, ending with silver. All of our Energy Harmonizers and pendants have eight alternating layers when the outside layer is 24K gold and nine layers when the outside layer is silver. The reason for the multi-layering is that it creates a thermocouple effect, generating a small voltage to be converted instantly to an electric current (measured in amperage) to increase the tools energy field.

Beads: According to inventor Nikola Tesla spheres are amplifiers, so Slim decided to add beads to some of the tools to amplify their beneficial effects. The more beads a tool features, the stronger its effects. Tools with beads have a stronger, denser tensor field – the beads essentially provide the rings with “more horsepower.” (NOTE: Light-Life Tensor Rings without beads are used mainly in outdoor applications, over irrigation systems, over smart meters, and also to sit on during long hours of travel to help reduce fatigue and stiffness).

Heavy Gauge Copper: For our Light-Life Heavy Tools, no silver or gold beads are required because the heavy gauge copper creates a stronger tensor field than the standard rings with beads, which may promote quicker health improvement.

Sterling Silver: Silver is a superior electrical conductor able to handle greater voltages and currents in electric circuitry. The sterling silver tools seem to work at a slightly different subtle level and appear to operate more smoothly and more quickly, due to a higher frequency. If you’ve never worked with Light-Life Tools, “smoother and quicker” may not mean anything to you – this statement came from practitioners who have worked with the copper tools for any length of time. They prefer now the sterling silver tools to the copper ones.

Sterling Silver Plated with 24K Gold (by request): Just as it does with the copper 24K gold plating adds a higher frequency due to the structure of the 24K gold atom in the crystal as it is applied to the tools.



The Light-Life Tools are manufactured in three different cubit measurements based on sacred geometry. They include Sacred Cubit, Lost Cubit and Empowerment Cubit. The larger the unit – the larger its resulting energy field. We also produce the Light-Life Tools in different wire gauges.

Sacred Cubit: The Sacred Cubit length was the first measurement used in the construction of the Light-Life Tools. It is taken from the Great Pyramid in Egypt and is the measurement of the perimeter of the “boss” – the little projection of stone 72.1 inches above the floor of the King’s Chamber. This unit of measurement is used throughout the pyramid and is a standard unit of measure, like a foot or a yard. It is equivalent to 20.6 inches and has a natural resonant frequency of 144 MHz, which is a harmonic of light speed.

Lost Cubit: In 2000, researcher and inventor Hans Becker discovered the Lost Cubit length, which was added to the measurements of the Light-Life Tools that same year. This unit of measurement is slightly larger than the Sacred Cubit and has a natural resonant frequency of 177 MHz (faster than the speed of light). It is safe to say this higher vibration would render it more powerful on some level.

Empowerment Cubit: In 2011 after extensive research and evaluation another cubit length was added to the line-up of Light-Life Tools. It is the final link in the trinity of cubit measurements (Sacred, Lost, and Empowerment).
