Far-infrared focused; not a substitute for a walk-in cabin, but a practical way to try heat therapy with almost no footprint. They also list a Clearlight-powered full-spectrum cabin (about $8,999 for the 3-person config on their page) if you want a walk-in later.
5. Sunlighten — established cabin brand (verify model)
5Research next
Sunlighten offers mPulse full-spectrum cabins and the Solo portable system. Solo documentation commonly cites ~120V / 1260W / 10.5A for U.S. power; residential heater warranty language often references multi-year / limited-lifetime style coverage — confirm the exact model’s guides & specs on sunlighten.com before buying. Live cabin pricing is often quote-based.
Who it’s for / not for: Shared family use favors wood cabins; apartments favor tent or blanket. Skip aggressive heat if your clinician advises against it.
Electrical: Match amps and plug type to your home — don’t assume “just plugs in.”
Warranty & returns: Prefer written years + clear RMA; SaunaSpace’s 100-day trial is unusually generous among tent systems.
