Solocarbon® Far Infrared Therapy

The Active Ingredient for the Highest Quality Infrared

Innováció fűtőbetét

To deliver health benefits like reduced blood pressure, weight loss, and detoxification, saunas need to emit high concentrations of infrared waves—not just heat.

That’s why Sunlighten worked with chemistry and coatings expert Dr. Ronald Lewarchik to develop its patented Solocarbon heating panels. The active ingredient in these panels is a special coating that emits the highest quality and quantity of infrared heat available from any sauna on the market.

The Proof is in the Process

Our patented heater design is our special sauce. Solocarbon panels are made up of three separate layers that are sandwiched together and cured at 160°C resulting in a nearly perfect black body. This unique process makes our far infrared heaters 95% emissive, safe, and effective. In fact, the materials used in our highly emissive coating are FDA approved which ensures that it is non-toxic. It is also a more efficient heat source and consumes less energy.

Solocarbon Heaters: A Perfect Equation for Vitality

Large Surface Area + High Emissivity + High IR Power = Therapeutic Results.

Total Surface Area

Far infrared waves have a regenerative effect on the body when emitted in the vital range of 7-14 microns. According to Wein’s Law, infrared energy at a lower surface temperature peaks in this vital range. The design of a Solocarbon heater allows for most of the far infrared wavelength to be near 9.4 microns, which is the level at which the human body absorbs infrared energy.

This is also the frequency at which a water molecule resonates or vibrates. This vibration causes a release of cellular toxins. This optimal micron output also allows for deeper penetration of far infrared heat, which improves pain relief, detoxification, weight loss, and skin purification. Our Solocarbon heaters maintain a constant, lower temperature that’s optimal for far infrared therapy. Heaters with larger surface areas create a more even distribution of heat so your sauna experience is both comfortable and therapeutic.


Emissivity is the ability of an object to emit or absorb energy.  A perfect black body has an emissivity of 1, emitting 100% of infrared energy.  An object with an emissivity of 0.6 will absorb 60% and reflect 40% of the energy.

For infrared therapy to be successful, sauna heaters must have a high emissivity level to deliver a high concentration of infrared waves.  As your body absorbs high levels of infrared, it begins to heal at the cellular level. Without high emissivity, a sauna may produce heat, but it won’t provide healing infrared. Sunlighten Solocarbon FIR heaters are clinically proven to be 95% emissive. 

Infrared Power

Infrared power is a measure of the concentration of energy (wattage density) and a prime indicator of heater quality. Heaters with higher wattage more effectively deliver infrared across the entire spectrum.

Infrared heaters have different outputs based on their wattage density and placement in the sauna. Solocarbon heaters are designed to emit the optimal amount of far infrared and are located in optimal positions within the sauna.

Clinically Backed for Quality & Safety

Our patented design and process are why Solocarbon panels are the only far infrared heaters clinically shown to raise core body temperature nearly 3° degrees for the most detoxifying sweat, lower systolic and diastolic blood pressure and aid in weight loss.

Not only are Solocarbon heaters the most effective on the market, they are also the safest. Our heater design produces virtually no EMF. With our exclusive manufacturing process, we can cancel out EMF to levels practically undetectable. Solocarbon heaters have gone through comprehensive third-party testing to ensure safe levels of EMF.

All heaters must be covered as a standard safety hazard precaution. Sunlighten provides non-toxic and highly emissive carbonized bamboo as a protective cover on our Solocarbon® heating technology, having our customer’s ultimate comfort & safety in mind!
