Sunlighten Amplify 1-Person
A legitimately full-spectrum cabin, with near-infrared from real 660 and 850 nm LEDs rather than far-infrared panels, but its under-1 mG EMF claim comes from a Sunlighten-commissioned Vitatech report that lists the Amplify II rather than this model.

Bottom line
In our scoring, Sunlighten Amplify 1-Person earns 5.2 out of 10 (Limited). Its low EMF claim carries no milligauss figure verified at the seated position, so we found no independent measurement to stand on. Its full spectrum label is backed by a real, separate near infrared emitter. This is informational only, not medical advice.
Our take
Sunlighten Amplify 1-Person lands in our lowest band, at 5.2 out of 10. It is strongest on Heat & Coverage (10.0/10) and weakest on Value (2.5/10). Key flag: EMF figure is brand-stated with no published third-party report. Confidence is Partial: specs are web-sourced, not yet reconfirmed from a primary source.
Its low-EMF claim is not backed by a named third-party figure measured where you sit. 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.

Who it is for
- · People who want genuine near-infrared from a separate emitter rather than far-infrared panels
- · 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
0.0/10 · 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.
- ·Brand-stated EMF, no third-party report C1 mG (brand claim) - A milligauss number with no named lab report behind it is a marketing claim, not a verified spec.
Spectrum disclosure
9.0/10 · 20%What the heaters actually deliver. Full spectrum is credited only with a separate near-infrared emitter; far-infrared panels alone are scored as far-infrared.
- +8True full spectrum (separate NIR emitter) A660/850 nm LEDs - Delivers near-infrared from a separate emitter rather than from far-infrared panels.
- +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 far-infrared panel.
- · Sunlighten's under-1 mG EMF claim comes from a Vitatech report it commissioned (VTE-3200, 2021), which lists the Amplify II and other Sunlighten models but not this one, 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 a seated-position EMF figure for this exact model.
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 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 report behind it does not cover this model. Sunlighten's commissioned Vitatech report (VTE-3200) lists maximum fields of 0.11 to 0.86 mG for five Sunlighten models, including the Amplify II but not the Amplify 1-Person, so in our scoring it earns no third-party EMF credit, and the EMF dimension stays capped until a report that names this model, or a seated figure, is published.
