Short answer
What is the difference between red light therapy and an infrared sauna?
The devices differ in size and heat. The wraps are pads and belts that shine 660nm red and 850nm infrared LEDs on the area they cover. The cabin is a 2-person room heated by far-, mid- and near-infrared elements, on 120V at up to 1,476W.
Side by side Choose red light therapy if Choose an infrared sauna if
Red light therapy and infrared sauna differ in device size, heat and how each device is used. A wrap shines light on the area it covers, while a cabin gives full-body heat in an enclosed room. Choose a wrap if you want a small device worn on the waist, back or legs; choose the cabin if you want full-body heat in a fixed room.

This article is informational and is not medical advice. Heat exposure strains the heart and causes fluid loss. Do not use a sauna after alcohol, when pregnant, when unwell, or with a heart condition or low blood pressure without asking a clinician first. Leave at once if you feel dizzy, sick or confused. For red light devices, avoid looking directly at the light beads.

Device size and fit
The wraps are small and wearable. The SmeFancy pad measures 14.4 x 6.1 in, with a 27.6 in long strap and a 15.7 in short strap. The MdyonM belt measures 51.2 x 7.1 in and fits waists up to 50 inches, for waist, back and legs. The SunSwell cabin measures 40.16 x 35.43 x 67 in and seats 2 people.
Light and heat settings
Both wraps state the same wavelengths: 660nm red and 850nm infrared. The SmeFancy pad offers 4 modes, including a pulse mode at 10HZ and 40HZ, flickering about 600/2400 times per minute. The MdyonM belt offers 3 modes, 5 intensity levels and 6 timer settings from 5 to 30 minutes. The SunSwell cabin names far-, mid- and near-infrared wavelengths without nanometer figures, from 6 heating elements: 3 mica panels and 3 red-light glass tubes, with temperature from 64°F to 149°F.
Power and setup
Both wraps run on the included adapter or a power bank, so they can move between rooms. The SunSwell cabin runs on 120V at up to 1,476W, with click-lock assembly that needs no extra tools, listed for assembly by 2 people. The cabin also lists 10 light colors, Bluetooth music, a cup holder and a towel rack.
What each listing leaves out
Neither wrap listing states a warranty term or a safety listing. The SunSwell listing states a 1-Yr Warranty but no safety listing. The sauna listing gives no nanometer figures for its wavelengths, so the sides cannot be compared on nanometers. The SmeFancy listing states no timer settings, and the MdyonM listing states no strap lengths.
