Solocarbon® Far Infrared Technology - Our Active Ingredient

If you are purchasing a sauna for health benefits, the single most important element to consider is heater emissivity which determines how efficient infrared heat is conducted and emitted. If a sauna is not efficient at emitting infrared, you are not receiving the benefits of infrared! Generic carbon blend heaters are less than 85% effective. Solocarbon® far infrared heaters are proven 95% efficient at emitting infrared. When researching infrared saunas, always ask for emissivity data. This determines the quality of infrared heat.

Clinically-Tested Heaters

Solocarbon® heating technology is the foundation for all of our sauna products. Signature saunas emit clinically-tested far infrared heat through heaters located on the floor, front, back and side wall panels.

It is the only heater on the market clinically shown to raise core temperature, lower blood pressure and aid in weight loss. This is one of the reasons more doctors recommend Sunlighten over any other sauna brand. Click here for reviews from wellness experts.
Ultra Low EMF Technology

Solocarbon® panels contain a unique proprietary blend of materials that are 100% quality controlled by Sunlighten™. This means—unlike other saunas on the market--we can ensure the safety & effectiveness of each individual heater. Solocarbon® panels are heat-sealed, meaning no wires or glues are used, so there is no release of unhealthy gases during heating.

Simple Magne-Seal™ Assembly process

Only Sunlighten offers a patented magnetic locking system, eliminating the need for unsightly clips to hold the sauna together. Benefits include:
  • Easy Assembly - walls easily snap together, making it a cinch to set up and take down
  • Prolonged Cabinetry - adapts as wood expands & contracts with heat to prevent cracks or warping
  • Heat Protection - better seals between the walls of your sauna mean heat stays in and cold air stays out
  • Durability - as strong and durable as clips, buckles or screws, but invisible to the eye so there’s nothing unsightly about your sauna
  • Double Reinforcement - combined with the hidden U-shaped clip and interlocking halo roof, the construction of your sauna could not be more secure.
