To deliver health benefits like heart health and detoxification, infrared heaters must emit high concentrations of the best infrared waves optimized for the human body to absorb. Sunlighten innovated an industry-game-changer we call SoloCarbon: a special coating that maximizes the highest quality and quantity of infrared available. Independent testing proves it is 99% effective. In Amplify, we amped up the heat factor with additional halogen heaters to get it hotter faster.
