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


The first and only infrared saunas to offer near, mid and far infrared technology. This smart technology is proven effective, customizable to individual needs and allows you to track results. These are not just home saunas, they are wellness tools that are adaptable to your health needs over time.

Solocarbon® 3-in-1 Infrared Therapy

Solocarbon® 3-in-1 full spectrum technology is unique in its ability to provide near, mid and far infrared in our home saunas at optimal wavelengths, proven effective.

+ Proven 99% efficient across all wavelengths for optimal health benefits – see study
+ Advanced LEDs provide true near infrared at a consistent output for cell rejuvenation and anti-aging
+ High power IF across near infrared, mid infrared, and far infrared wavelengths – a prime indicator of heater quality
+ Emissive coating produces more infrared per square inch over any other heater on the market – See Documentation

Near Infrared

Near infrared (NIR) is the shortest infrared wavelength.  Scientific research shows that when delivered at the vital wavelength of 880nm, without extreme heat or light, NIR promotes skin renewal, cell health, wound healing, and tissue growth.  LEDs are effective because they can trigger a natural photo-biochemical reaction, similar to how plants use chlorophyll to convert sunlight into plant tissue.  And when the wave is pulsed, it can travel deeper into tissues.  mPulse saunas got their name because the LED pulsate for optimal benefits.  Learn more.

Mid Infrared

Mid infrared (MIR) is a longer wavelength that can penetrate deeper into the body’s soft tissue where inflammation occurs and speeds up the healing process. To produce MIR, sauna heaters must be able to maintain a surface temperature of 210⁰C. Though many sauna companies claim to provide full spectrum, the material used in their heaters actually melts at the high temperature required for MIR. We worked with engineers and scientists to source a high tech material made to withstand the temperature required.  Learn more.

Far Infrared

The longest wavelength, far infrared (FIR), reaches deepest into the body, where toxins are stored. We've already achieved the most effective far infrared heater with our highly emissive Solocarbon  heater coating  and have applied that same coating to our polyimide panel.  Instead of being sandwiched between layers, the coating is on the exterior of the heating panel.  During the testing process, we discovered this application makes it 99% emissive!  Learn more.

7 Wellness Programs

Because the three heating mechanisms within our full spectrum heaters operate independently, you can program them to generate any combination of NIR, MIR, and FIR heat. You can optimize the IR power, output, and intensity based on your specific needs during each sauna session. Or you can choose one of our preset wellness programs.

Research shows that specific parts of the infrared spectrum are effective at producing different health benefits. Our 3-in-1 sauna blends the optimal wavelengths—near, mid, and far—to achieve specific results. Eight preset wellness programs are ready to use at the touch of a button.

Simple MagneSeal Assembly

Sunlighten’s patented Magne-Seal™ assembly process maintains the integrity of the sauna while allowing you to easily snap together walls making it a cinch to set up and take down. 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 the cool air out. It is as strong and durable as clips, buckles or screws, but invisible to the naked eye.
