Amplify II

Engineered around how energy reaches your body

Red and near-infrared light, integrated throughout the sauna
Photobiomodulation (PBM) uses both visible red and invisible near-infrared light. We’ve integrated both throughout the sauna, with placement engineered for how your body receives light.
Purposeful infrared, layer by layer
Therapeutic far-infrared and full-spectrum heat each play a distinct role, while refined temperature control, thick insulation and double-pane glass help retain heat up to 170°F *. Layer the experience your way.
Not maximum light. The right light
With PBM, wavelength, distance and dose matter not just raw power. Amplify RED’s red + NIR system is designed around these principles, informing where the light is placed and how it reaches your body.
Safe, industry-leading technology
At its foundation is Sunlighten’s patented far-infrared technology, engineered for 99% emissivity and ultra-low EMF.
