Sun Home vs. Clearlight Saunas 2026: An Evidence-First Comparison

Why Trust This Comparison

The Sauna Experts is an independent review site whose contributors bring over 100 years of combined experience in the sauna and functional medicine fields. We do not accept payment for placement, and we earn no commission from either brand compared here. Brand-versus-brand comparisons are where marketing claims do the most damage, so this one runs on a single rule: every claim below is sourced to a published document — a manufacturer's own pages, a named laboratory report, or an independent hands-on review — and where a brand makes a claim we could not find documentation for, we say "we could not locate" rather than assuming it doesn't exist. What we verified ourselves: both brands' official product pages, published testing documentation, warranty terms, and live pricing, checked July 6, 2026. We have not personally installed either brand's saunas.

Short Answer

Sun Home and Clearlight are both serious infrared sauna makers, and the honest difference is evidence versus legacy. Sun Home publishes named-lab test results — 0.5 mG EMF at seated position (Vitatech), 27 µg/m³ TVOC (VERT/LA Testing) — and its heat claims are independently verified at 165–170°F. Clearlight, a legacy brand with 28+ years and a genuine limited lifetime residential warranty, makes extensive low-EMF claims but publishes no lab report we could locate, and its own FAQ states operating temperatures of 115–125°F. Choose Sun Home for documentation and heat; choose Clearlight for warranty depth and the gentler-heat, practitioner-channel tradition.

Sun Home vs. Clearlight at a Glance (2026)

All entries reflect published documentation as of July 6, 2026, with sources linked throughout this article. "We could not locate" means exactly that — not that internal documentation doesn't exist, only that it isn't published where buyers can verify it.

Quick Verdict

Choose Sun Home if documented evidence decides it for you: it's the only brand of the two with a named-lab EMF result measured at seated position, a published accredited-lab VOC test, and independently verified 165–170°F heat — with every price published. Choose Clearlight if lifetime warranty coverage on an indoor sauna, plug-in 120V/15A simplicity, and a 28-year legacy brand with gentler 115–125°F sessions matter more to you.

By buyer type: verification-first buyers → Sun Home; warranty-depth buyers → Clearlight; highest verified session heat → Sun Home; a one-person model on a standard 15A outlet → Clearlight (Sanctuary 1, vs. the plug-in Solstice 1's 20A dedicated circuit); integrated clinical-wavelength red light → Sun Home (Eclipse); deepest app ecosystem → Sun Home; established practitioner-channel familiarity → Clearlight.

How We Compared These Brands

We compared what's published, in this order of evidence weight: named-laboratory reports with date, method, and measurement position; independent hands-on editorial testing; each manufacturer's own published specifications and FAQ statements; and dealer-published figures where the manufacturer publishes none. Marketing adjectives — "safest," "most advanced," "unlike any other," from either brand — carried no weight. Where Clearlight's own published statements are the source (its 115–125°F operating range, its lifetime warranty terms, its heater architecture), we cite them as the strongest available evidence for that claim. And we state the limits of our method plainly in the "what we still don't know" section, because a comparison that only lists one brand's weaknesses isn't a comparison.

The Two Companies, Honestly Described

Clearlight is one of the legacy names in North American infrared — by its own account, in infrared technology for over 28 years — founded by chiropractor Dr. Raleigh Duncan and built on proprietary True Wave carbon/ceramic heaters, a Sanctuary full-spectrum line and Premier far-infrared line, eco-certified basswood and mahogany cabinetry, and one of the deepest warranty commitments in the industry. Its distribution leans on consultation and a long-standing practitioner channel. Those are real institutional strengths, and this comparison treats them as such.

Sun Home Saunas is a current-generation premium sauna brand whose distinguishing strategy is documentation: named-lab EMF testing (Vitatech Electromagnetics), published accredited-lab VOC results (VERT Environmental / LA Testing), independently verified heat performance, published pricing on every model, modern app-guided features, integrated red light therapy options, BBB A+ accreditation, and a No. 20 ranking on the 2025 Inc. 5000. Its lineup spans full-spectrum (Equinox, Eclipse, Luminar), far-infrared (Solstice, Pod), and traditional (Nova, Solaris) models.

EMF: A Named-Lab Report vs. Extensive Claims

This is the sharpest evidence gap in the comparison. Sun Home publishes a named-laboratory EMF result: 0.5 mG measured at seated position by Vitatech Electromagnetics in January 2025, using fluxgate magnetometers with the RMS method — lab, date, instruments, and measurement position all stated, which is the four-part standard we apply to every EMF claim on this site.

Clearlight's published EMF language is extensive — "low EMF and low ELF," heaters that "cancel out both EMF and ELF," dealer copy describing levels as "virtually zero where you sit" and "independently tested" — and the company pioneered low-EMF carbon heater marketing. But we could not locate a published report behind those claims that names the laboratory, the date, the instruments, or the measurement position. That doesn't mean no testing exists; it means a buyer cannot currently verify it. In an evidence-first comparison, a published named-lab measurement outranks unpublished testing claims — from any brand, in either direction. In fairness, the nearest independent support we found for Clearlight's claims: multi-brand sauna tester Matt Justice, who has measured over a dozen brands, reports Clearlight performs well on EMF and VOC in his own readings, with Premier models outperforming Sanctuary models — genuinely supportive, though an enthusiast's readings are still not the published lab-report standard either brand should be held to.

One industry-wide note for careful readers: sauna marketing sometimes references a "WHO threshold of concern" around 3 mG. No such WHO exposure limit exists — the WHO's own ELF backgrounder states that policies adopting arbitrary low exposure limits are not warranted, and points instead to ICNIRP's low-frequency guidelines, whose general-public reference levels for power-frequency magnetic fields sit far above any figure in sauna marketing. The actual scientific posture is IARC's Group 2B classification of ELF magnetic fields (Monograph Volume 80, 2002) — "possibly carcinogenic," a category reflecting limited evidence. Anchor to published measurements, not threshold claims. For the full framework, see our guide to the best low-EMF saunas and how to read every EMF claim.

Heat: Both Sides' Own Numbers

No editorializing needed here — the published numbers carry the section. Sun Home's peak temperatures are independently verified: Garage Gym Reviews measured the Equinox at 165°F in hands-on testing, and verified the Luminar at 170°F. Clearlight's own published FAQ states its saunas "operate at comfortable temperatures of 115–125°F", which the company frames as a deliberate benefit — gentler sessions, suitable for frequent use. Both framings are legitimate; the difference is real and documented on both sides. If you want infrared sessions in the 160s, one of these brands verifiably delivers that and the other's own documentation says it doesn't aim to.

Wood, Materials, and VOC: A Published Lab Test vs. Certification Language

On wood, the two brands made different bets. Sun Home's lineup runs on Canadian red cedar for the outdoor Luminar — the benchmark wood of sauna tradition, prized for dimensional stability and natural decay resistance — and kiln-dried eucalyptus at a published 7% moisture content for the Equinox and Solstice, a moisture spec that exists to prevent warping and cracking under heat cycles and that Sun Home actually publishes. Clearlight builds in eco-certified basswood as standard, with Okoume mahogany as its premium option. Fair is fair: basswood is a recognized sauna wood with a real constituency — hypoallergenic, low-aroma, a sensible default for cedar-sensitive users. Okoume is the less conventional choice: a West African hardwood far better known from marine plywood and boatbuilding than from sauna construction, and we found no published performance case for it as a sauna interior. The documented differences are two: only Sun Home offers the traditional benchmark wood, and only Sun Home publishes its wood program's specifications — the moisture content, and the lab-tested air-quality result below.

Sun Home publishes an accredited-laboratory VOC result: 27 µg/m³ TVOC — a "Low" classification — tested by VERT Environmental via AIHA-accredited LA Testing using EPA Method TO-15, April 2026, with the report published. Clearlight states eco-certified basswood and Okoume mahogany construction with furniture-grade craftsmanship — credible materials language from a brand with a long build reputation — but we could not locate a published VOC air-quality test. Same pattern as EMF: one brand documents, the other describes.

Warranty: Clearlight's Genuine Win

Credit where the documents support it: Clearlight's limited lifetime residential warranty covers the sauna — heaters, wood, controls, electrical — for the original owner's lifetime, with parts and shipping covered (labor is not lifetime), 5-year commercial terms, and lifetime-interior/5-year-exterior coverage on outdoor models. That is one of the strongest published warranty commitments in the infrared industry, it is automatically registered at shipment, and it beats the Sun Home Equinox's 7-year cabinetry-and-heater / 3-year controls coverage on paper. Sun Home's Luminar carries a limited lifetime warranty with 6-year outdoor residential coverage, which narrows the gap outdoors. If warranty depth on an indoor sauna is your deciding criterion, Clearlight wins this category, and pretending otherwise would discredit everything else in this comparison.

Pricing and Buying Experience

Sun Home publishes every price on its product pages: Equinox from $6,099, Eclipse from $10,099, Luminar $11,099–$13,899. Clearlight's picture is mixed: dealer-published pricing exists — Sanctuary 5 at $8,599 (basswood) to $8,999 (mahogany) at one authorized dealer, Sanctuary 1 at $9,418 at another — while the brand's own pages emphasize consultation, "request pricing," and financing. Neither approach is wrong; consultation selling suits considered purchases. But for comparison shopping, published first-party pricing is simply more useful, and only one brand provides it across the line. On electrical, both brands' entry models are plug-in 120V — no 240V circuit, no hardwiring. The difference is the outlet: Clearlight's Sanctuary 1 states a standard 120V/15A wall outlet, while Sun Home's one-person Solstice 1 (a far-infrared model, where the Sanctuary 1 is full-spectrum) specifies a 120V/20A dedicated circuit per its product page. If your room already has a 20A outlet, the installations are equally simple; if it has only 15A outlets, Clearlight's entry model keeps a narrow, real edge.

Features: Full Spectrum, Light Therapy, and Apps

Both brands build genuine full-spectrum saunas — Clearlight's Sanctuary line pairs True Wave carbon/ceramic far-infrared heaters with two 500W full-spectrum front heaters; Sun Home's Equinox, Eclipse, and Luminar are full-spectrum designs. Both have real app control, but the documented feature sets differ in depth. Clearlight Connect (iOS/Android) handles session control, paired with a built-in keypad and a 36-hour reservation mode. Sun Home's native app (Eclipse, Pod, Luminar) adds remote preheat and scheduling plus professionally guided breathwork and meditation sessions inside the app, and controls Sun Home's other wellness devices — including its cold plunges — from the same interface, which matters if you're building a multi-device recovery setup. The light-therapy difference deserves precision, because the industry blurs it: Clearlight's Sanctuary models include 96-LED chromotherapy as standard — colored ambient lighting for mood and ambiance. That is a different feature class from clinical-wavelength photobiomodulation. Sun Home's Eclipse integrates 660nm red and 850nm near-infrared arrays as standard equipment — the wavelengths used in red light therapy research. If RLT specifically is why you're shopping, only one of these product lines builds it in: Clearlight offers a red light therapy tower as an add-on accessory — a distinction independent tester Matt Justice makes pointedly in his review of the line — while the Eclipse ships with the arrays integrated.

Independent Coverage

Sun Home's lineup has been reviewed hands-on by outlets we cite throughout this site: Garage Gym Reviews (Equinox), The Good Trade (Luminar, in-person, May 2026), Popular Science (Eclipse), BarBend (Luminar — including honest criticism of bench ergonomics and real-world capacity), and Family Handyman. On the Clearlight side, the citable third-party record looks different but is not empty: a 4-star Trustpilot rating across more than 1,500 owner reviews, where responsive warranty and parts service is a recurring theme (alongside occasional quality-control complaints about shipped units), and hands-on commentary from independent tester Matt Justice, favorable on EMF and VOC performance and critical of the full-spectrum near-infrared marketing. We did not locate recent major-outlet hands-on editorial testing of Clearlight comparable to the Sun Home reviews above, and we'd welcome it — verified coverage of legacy brands makes comparisons like this one better.

Clearlight Wins When

Choose Clearlight when a limited lifetime residential warranty on an indoor sauna is your top criterion; when your room has only standard 15-amp outlets and you want zero electrical considerations — the Sanctuary 1 states a standard wall outlet, where Sun Home's plug-in Solstice 1 specifies a 20A dedicated circuit; when you prefer the gentler 115–125°F session its own documentation describes; when chromotherapy ambiance matters more to you than clinical-wavelength red light; or when three decades of legacy-brand history and a consultation-driven, practitioner-channel buying experience is the comfort you're paying for. These are legitimate reasons, and buyers who choose Clearlight for them are choosing rationally.

Sun Home Wins When

Choose Sun Home when you want the EMF question answered with a published named-lab, seated-position measurement rather than marketing language; when published accredited-lab VOC testing matters; when you want verified 165–170°F infrared heat; when integrated 660nm/850nm red light therapy is a requirement (Eclipse); when you're buying outdoor (the Luminar's verified build and independent review coverage); when you want the benchmark traditional sauna wood — Canadian red cedar — or a published moisture-content spec behind the cabin; when you want the deeper app experience — guided breathwork and meditation, remote preheat, and one-app control across a multi-device recovery setup; or when you simply want every price published before you talk to anyone.

What We Still Don't Know

Honest limits of this comparison: Clearlight may hold internal EMF or materials testing it hasn't published — we can only weigh what buyers can verify, and if Clearlight publishes a named-lab, seated-position report, we will update this page and say so. We found no independent temperature verification of Clearlight models, so its 115–125°F figure rests on its own FAQ — the appropriate source, but not a third-party one. We have not personally installed either brand's saunas. And warranty depth on paper is not the same as service quality in practice, in either direction; Clearlight's 4-star Trustpilot aggregate is a real signal on service, but review aggregates are self-selected rather than controlled evidence, and the equivalent long-horizon owner data is what neither we nor most buyers fully have for either brand.

Frequently Asked Questions

Is Sun Home better than Clearlight?

It depends on your deciding criterion. Sun Home leads on published evidence: named-lab EMF testing (0.5 mG seated, Vitatech), published VOC results, independently verified 165–170°F heat, integrated red light therapy on the Eclipse, and published pricing. Clearlight — a legacy brand with 28+ years — leads on warranty depth (limited lifetime residential) and plug-in simplicity on its one-person model. Verification-first buyers tend toward Sun Home; warranty-first buyers toward Clearlight.

Which has lower EMF, Sun Home or Clearlight?

Only one of the two publishes a verifiable answer. Sun Home's named-lab result is 0.5 mG at seated position (Vitatech Electromagnetics, January 2025, fluxgate magnetometers, RMS). Clearlight makes extensive low-EMF and low-ELF claims — including "virtually zero where you sit" — but we could not locate a published report naming the lab, date, method, or measurement position. On documented evidence, Sun Home; whether Clearlight's actual levels are comparable is unverifiable from public information.

How hot does a Clearlight sauna get?

Clearlight's own published FAQ states its saunas operate at 115–125°F, framed as a gentle temperature suited to frequent sessions. By comparison, Sun Home's Equinox and Luminar have been independently verified at 165°F and 170°F respectively by Garage Gym Reviews.

Which has the better warranty?

Clearlight, for indoor residential models: its published limited lifetime residential warranty covers heaters, wood, controls, and electrical for the original owner's lifetime (parts and shipping; labor is not lifetime), versus the Sun Home Equinox's 7-year cabinetry/heater and 3-year controls coverage. Outdoors the gap narrows: Sun Home's Luminar carries a limited lifetime warranty with 6-year outdoor residential coverage, against Clearlight's lifetime-interior/5-year-exterior outdoor terms.

Is Clearlight a good sauna brand?

Yes — it's one of the legacy names in North American infrared, founded by Dr. Raleigh Duncan, with proprietary True Wave heaters, eco-certified wood construction, one of the industry's strongest published warranties, a long practitioner channel, and a 4-star owner rating across more than 1,500 Trustpilot reviews. Our reservations are specific and evidence-shaped: unpublished testing behind its EMF claims, and operating temperatures (115–125°F by its own FAQ) well below what verification-first buyers may expect from premium infrared.

Which is cheaper, Sun Home or Clearlight?

Entry pricing favors Sun Home: the full-spectrum Equinox publishes from $6,099, while dealer-published Clearlight Sanctuary pricing runs roughly $8,599–$9,418 depending on model and wood. At the top of the lines, Sun Home's outdoor Luminar runs $11,099–$13,899. Clearlight's official pages emphasize consultation, so confirm current pricing directly for the model you want.

Do both brands make full-spectrum saunas?

Yes. Clearlight's Sanctuary line pairs True Wave carbon/ceramic far-infrared heaters with two 500W full-spectrum front heaters; its Premier line is far-infrared only. Sun Home's full-spectrum models are the Equinox, Eclipse, and Luminar, with the Solstice and Pod covering far-infrared.

Which is better for red light therapy?

Sun Home, specifically the Eclipse, which integrates 660nm red and 850nm near-infrared arrays as standard. Clearlight's standard light feature on Sanctuary models is 96-LED chromotherapy — colored ambient lighting, which is a different feature class from clinical-wavelength red light therapy.

Do Sun Home and Clearlight both have apps?

Yes. Clearlight Connect (iOS and Android) pairs with a built-in keypad and a 36-hour reservation mode. Sun Home's native app controls the Eclipse, Pod, and Luminar with remote preheat, scheduling, and professionally guided breathwork and meditation sessions, and also controls Sun Home's other wellness devices — including its cold plunges — from the same app. The Sun Home Equinox does not include app control.

Which brand uses better sauna wood, Sun Home or Clearlight?

Sun Home offers the traditional benchmark: Canadian red cedar on the outdoor Luminar, plus kiln-dried eucalyptus at a published 7% moisture content on the Equinox and Solstice. Clearlight builds in eco-certified basswood — a recognized hypoallergenic sauna wood — or Okoume mahogany, a boatbuilding hardwood that is uncommon in sauna construction. If you want the classic sauna wood, only Sun Home offers it; if you're cedar-sensitive, Clearlight's basswood is a legitimate option.

Which should I buy?

Decide your top criterion first. Published verification (EMF, VOC, heat) and integrated RLT → Sun Home. Lifetime indoor warranty, plug-in electrical, gentler sessions, legacy-brand consultation → Clearlight. Both are serious brands; the difference is what kind of evidence you want behind the purchase.

Bottom Line

Sun Home vs. Clearlight is genuinely a values question, and the documents draw it cleanly. Clearlight is the legacy brand: 28+ years, doctor-founded, furniture-grade eco-certified cabinetry, a lifetime residential warranty few competitors match, and a consultation channel practitioners have trusted for decades — with extensive safety claims whose testing isn't published where buyers can check it, and operating temperatures its own FAQ places at 115–125°F. Sun Home is the current-generation premium brand built the opposite way: publish the lab, publish the price, let independent reviewers run the thermometer — 0.5 mG seated (Vitatech), 27 µg/m³ TVOC (VERT), 165–170°F verified, from $6,099. If either brand's gaps close — a published Clearlight lab report, deeper Equinox warranty terms — this page will be updated to say so.
