Infrared sauna · cabin
Sunlighten Amplify 1-Person
A legitimately full-spectrum cabin, with near-infrared from real 660 and 850 nm LEDs rather than a relabeled panel, but its under-1 mG EMF claim is position-sensitive and independent meters read up to about 2 mG at the seat.
This sauna publishes a named third-party report with a low figure, but not at the seated body position, so it earns partial - capped - EMF credit rather than full. EMF is our heaviest dimension, so an unverified claim alone can hold a sauna in a lower band. Read this score as "the headline EMF claim is not proven at the seat", not "bad sauna" - the build, heat, and value dimensions below tell that part of the story.
Flags
- · A named third-party lab measured a low figure, but not at the seated body position (read at the heater, or the seat is contested), so the low-EMF claim is not yet verified where you sit. Credited in part for the documented testing; the dimension stays capped until a seated figure is published.

Who it is for
- · People who want genuine near-infrared from a real, separate emitter, not a relabeled panel
- · Buyers who want a fixed cabin with an electrical-safety listing
Who should skip it
- · Anyone buying specifically for low EMF - the claim here is not verified at the seated body position
How it scored
Verified EMF
2.0/10 · 30%A low magnetic-field (mG) figure measured at the seated body position by a named third-party lab. A figure measured at the heater, an unsourced number, or a bare low-EMF label is not a usable spec.
- +2Third-party report, low figure, but not at the seat B1 mG, named lab, position not the seat - A named lab measured a low figure, which is more than a bare claim, but not where you actually sit, where the field can read higher. Credited in part and capped until a seated figure exists.
Spectrum Honesty
9.0/10 · 20%What the heaters actually deliver. Full spectrum is honest only with a separate near-infrared emitter, not a far-infrared panel relabeled.
- +8True full spectrum (separate NIR emitter) A660/850 nm LEDs - Delivers near-infrared from a real, separate emitter, not a far-infrared panel relabeled.
- +1Named near-infrared source A660/850 nm LEDs - The near-infrared source is identified, so the claim can be checked.
Heat & Coverage
10.0/10 · 15%Heater count and placement that surround the body (including a floor or foot heater), and the temperature reached.
- +4Surrounds the body B6 heaters - Six or more heaters across the walls give even coverage rather than one hot spot.
- +3Floor or foot heater Bfloor heater - A floor or foot heater warms the hardest area to heat, a sign of real surround design.
- +3Reaches full sauna temperature B150 F - Reaches the 140 F range expected of a cabin sauna.
Value
2.5/10 · 20%Price against the median for its type (blanket, tent, or cabin).
- +2.5Price vs class median A$5,800 (near class median) - Price scored against the median for its type. Class median about $5,500.
Safety & Build
9.0/10 · 15%Electrical-safety listing (UL/ETL), recall history, warranty, and materials.
- +5UL/ETL electrical-safety listed AETL/UL - Carries an electrical-safety listing, important for a high-wattage heater you sit beside.
- +3Long warranty B7-year - Five-year or longer warranty.
- +1Cabin wood disclosed CBasswood - The cabin wood is disclosed.
What to know before buying
- · A legitimately full-spectrum cabin: near-infrared comes from real 660 and 850 nm LEDs, a separate emitter rather than a relabeled panel.
- · The under-1 mG EMF claim is position-sensitive; independent TriField testing reads 0.5 to 2.0 mG at the seat, so we do not credit it as verified at the body.
- · Six SoloCarbon far-infrared heaters plus the LED array, with a floor heater, ETL-listed.
- · Seven-year warranty.
- · Strong full-spectrum hardware; the open question is the seated-position EMF, which is contested.
FAQ
- Is the Amplify genuinely full spectrum?
- Yes, in our scoring. Its near-infrared comes from real 660 and 850 nm LEDs, a separate emitter rather than a relabeled far-infrared panel, alongside six SoloCarbon far-infrared heaters and a floor heater. It is also ETL-listed (Intertek), which we credit.
- Why don't you credit its under-1 mG EMF claim as verified?
- Because the position is contested. A Vitatech report claims under 1 mG, but independent TriField testing reads 0.5 to 2.0 mG at the seat, so in our scoring we credit the documented testing in part and cap the EMF dimension until a seated figure is settled.
