Clearlight Sanctuary 1
Pairs a genuine added full-spectrum heater with the same Clearlight-commissioned Vitatech tests of bare far-infrared heater panels (peaks of 0.12 to 0.36 mG at 2 inches); no seated in-cabin reading is published, and the tests do not cover the full-spectrum heater.

Bottom line
In our scoring, Clearlight Sanctuary 1 earns 5.8 out of 10 (Limited). Its 0.36 mG figure is measured at the heater rather than where you sit, so we found no independent reading at the seated position. Its full spectrum label is backed by a real, separate near infrared emitter. This is informational only, not medical advice.
Our take
Clearlight Sanctuary 1 lands in our lowest band, at 5.8 out of 10. It is strongest on Heat & Coverage (10.0/10) and weakest on Verified EMF (2.0/10). Key flag: 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.
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.

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
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 B0.36 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 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) Adedicated full-spectrum (near/mid/far) heater - Delivers near-infrared from a separate emitter rather than from far-infrared panels.
- +1Named near-infrared source Adedicated full-spectrum (near/mid/far) heater - 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 B140 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$6,799 (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 B99-year - Five-year or longer warranty.
- +1Cabin wood disclosed CBasswood - The cabin wood is disclosed.
What to know before buying
- · Pairs a genuine added full-spectrum heater with Clearlight-commissioned Vitatech tests of bare heater panels (peaks of 0.12 to 0.36 mG at 2 inches); no seated in-cabin reading is published, and the tests do not cover the added full-spectrum heater.
- · A real near-infrared source is the verified half of the picture here; the EMF half is a documented heater-level reading, not a seated one.
- · Carbon-ceramic hybrid heaters plus a dedicated full-spectrum element, with calf and floor coverage, ETL-listed.
- · Lifetime residential warranty.
- · If you want full spectrum with a lifetime warranty, this is a strong pick; just know its EMF is not verified at the seat.
FAQ
- How does the Sanctuary 1 score on EMF and spectrum?
- In our scoring it clears the true full-spectrum test with a dedicated added (near, mid, far) heater, which most units cannot. Its EMF rests on Clearlight-commissioned Vitatech tests of bare heater panels (peaks of 0.12 to 0.36 mG at 2 inches), a documented low reading we credit in part, but not a seated in-cabin reading, so the EMF dimension stays capped.
- Is its near-infrared a separate emitter or a far-infrared panel?
- A real one, as we read it. Alongside the carbon-ceramic hybrid True Wave heaters, it adds a dedicated full-spectrum element covering near, mid, and far, so in our scoring the full-spectrum claim earns credit rather than a cap. It is ETL-listed with a lifetime residential warranty.
