1st & Only: Patented Solocarbon™ 3-in-1 Infrared

Solocarbon 3-in-1™ infrared heaters are the only sauna heaters on the market that produce near, mid and far infrared wavelengths. Certain conditions are necessary in order to generate each individual wavelength, so our 3-in-1™ heaters include three distinct heating mechanisms. Other manufacturers may claim to provide full spectrum infrared, however their heaters do not have the technical capacity to deliver on that promise.

Patented Solocarbon™ Far Infrared 

Sunlighten Solocarbon™ far infrared heating panels are the most effective far infrared sauna heaters on the market to day. Solocarbon™ panels are proven 95% emissive, meaning that 95% of the energy being produced is in the peak range of infrared to increase core body temperature for a deep, therapeutic sweat.

This is the active ingredient in the effectiveness of Sunlighten Saunas.

Magne-Seal Assembly Technology

Sunlighten's patented Magne-seal™ technology maintains the integrity of your sauna while simplifying the assembly process.

As the sauna naturally expands and contracts during use, Magne-seal™ adapts to prevent cracks and warping for prolonged cabinetry, while keeping the heat in and cool air out. 

*Patent No. US7,458,111 B2

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 temperatures nearly 3°.

Our heater design produces virtually no EMF.  With our exclusive manufacturing process, we can cancel out EMF to levels practically undetectable.

Our saunas offer the most effective infrared heating technology, along with unsurpassed levels of safety. Sunlighten saunas have undergone comprehensive third party testing to ensure safe levels of EMF. See testing.

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!
