Solocarbon® – The most effective far infrared technology

Solocarbon® is Sunlighten’s proprietary far infrared technology that is 95% effective and the only heater on the market clinically shown to raise core temperature, lower blood pressure and aid in weight loss.

Solocarbon® Full Spectrum – Advanced blend of near, mid and far infrared heat

We have taken infrared therapy to the next level with Solocarbon 3-in-1® .  This patented technology has three separate heating elements to provide near, mid and far infrared at optimal wavelengths based on 56 clinical studies. Others may claim to provide full spectrum infrared, but their heaters simply don’t have the technical capability to deliver in the therapeutic range. Solocarbon 3-in-1 can evolve with changing health needs over time.

non toxic


Safe, Non-toxic Materials

All elements of Sunlighten saunas are made with safe, non-toxic materials. Not only are our Solocarbon heaters proven 95-99% efficient, they contain a proprietary blend of FDA-approved materials and are heat-sealed to withstand temperatures above and beyond the operating temperature  to ensure no unhealthy gases are released during heating. Plus, extensive third-party testing has been conducted to ensure all of our materials are safe and non-toxic.

low emf


Low EMF Levels Provide a Safe and Effective Sauna Experience

Sunlighten Solocarbon heaters are the most effective—and the safest—infrared heaters on the market.  Sunlighten saunas have met the strictest safety standards for more than a decade. Our patented heater design has a 95-99% emissivity rating and cancels out EMF to levels that are virtually undetectable—less than 1mG for Signature and Solo.  

safety standards


Sunlighten adheres to the upmost safety standards.  Electrical certification ensures that your sauna has been tested to meet safety and performance standards.  Many consumers do not even think about or look to see if a product displays a safety agency mark.  Without a safety agency listing, there is no proof that a product passes electrical safety standards.
