The Sunlighten Amplify II is an infrared cabin. Its panels warm your body directly while the air holds around 45–60°C (113–140°F), so sessions run 30 to 45 minutes. A traditional sauna heats the air to 80–100°C. Infrared or traditional?
What to know before you buy
Basswood, full-spectrum, 120V plug-in. These decide whether it suits your space and your electrical panel.
- BasswoodBasswood is hypoallergenic and has no scent of its own. Choose it if cedar's aroma is too much for you.
- Full-SpectrumA full-spectrum cabin gives you the widest wavelength coverage you can buy, since it adds near and mid infrared to far infrared in one room.
- 120V Plug-InA plug-in model runs on a standard household outlet, so you won't need an electrician. Check whether it needs its own dedicated circuit.
