Sun Home Saunas vs Clearlight (2026): Which Infrared Sauna Brand Is Better?

Both are credible infrared sauna brands, and the right answer depends on the exact models and your priority. Choose Sun Home if independently observed high-temperature performance, an aluminum outdoor cabin, factory-integrated red light therapy on Eclipse, published named-lab EMF and VOC reports, and the broader recent record of independent editorial recognition matter most. Choose Clearlight if lifetime component coverage, longer labor coverage, showroom access before purchase, and an operating history dating to 1997 matter most. The brands have not been tested head-to-head under matched conditions, so compare exact models rather than treating either company as universally better.

Disclosure: Sun Home publishes this article and manufactures several products compared below. Clearlight did not review or approve it. Manufacturer specifications, controlling warranty documents, named-laboratory reports, third-party observations, and company signals are labeled separately throughout, and no side-by-side testing between the brands was conducted for this article.

How We Compared

Five evidence classes are kept distinct because they answer different questions. Manufacturer specifications come from each brand's live product pages and price lists. Controlling warranty documents govern coverage claims and take precedence over marketing copy, including our own. Named-laboratory reports are cited with the test article, setup, and measurement conditions, and their limits are stated — two reports from the same lab on different test articles are not a matched comparison. Third-party observations are attributed to the named reviewer under that reviewer's conditions. Company and research signals — brand tenure, corporate relationships, clinical study participation, editorial recognition — describe the businesses rather than measuring the cabins, and are confined to their own section. Where a figure could not be located in a brand's public materials, this guide says so rather than estimating. Clearlight is a long-tenured legacy brand in this category, and this comparison credits its genuine advantages where the documents support them.

Exact Model Pairs and Current Prices

Comparing a brand's cheapest far-infrared cabin against another brand's flagship full-spectrum model produces a meaningless number. These are like-for-like pairs.

Two corrections to how this comparison has been framed before. First, the frequently cited "Clearlight from about $6,499" figure belongs to a mahogany Premier 2 — a far-infrared cabin — not to the full-spectrum Sanctuary line, so it should never be used as the Sanctuary starting price. Second, Clearlight now publishes a direct residential price list, so transparent online pricing is no longer a Sun Home differentiator. On the closest pair, the Equinox 2 is meaningfully below the Sanctuary 2 Basswood. On outdoor, the comparison reverses: the Sanctuary Outdoor 2 is meaningfully below the Luminar 2, and buyers should weigh that against the exterior material and cover requirement rather than assuming the pricier cabin wins.

On red light, compare total configured cost: an Eclipse 2 at $10,599 with factory-integrated towers against a Sanctuary 2 at $7,199 plus a tower, which lands meaningfully lower for the Personal Tower and still below the Eclipse with the Core Tower — while delivering a freestanding device rather than an integrated one.

Warranty: The Component Schedules Side by Side

Warranty headlines are the least reliable part of this category. Both brands publish a limited lifetime designation, and the schedules underneath them differ substantially, so this section works from each company's controlling document rather than its marketing copy.

Sun Home's published warranty — the current warranty page — provides the following for residential use. Equinox and Solstice: 7 years on cabinetry and heaters, 3 years on controls, 1 year on glass doors and audio. Eclipse and Pod: a limited lifetime designation on cabinetry and heaters that the document defines as up to 7 years, plus 3 years on controls and 1 year on LED lighting, glass doors, and audio. Luminar: the same limited lifetime designation on cabinetry and heaters, 3 years on the exterior cabin, 3 years on controls, and 1 year on LED lighting, glass doors, and audio. Across these models, parts, labor, and shipping are included for the first 90 days from delivery; after 90 days the customer is responsible for all shipping and labor charges. Sun Home repairs or replaces at its election. The document does not promise technician dispatch, define a service network or territory, or identify which repairs qualify for an on-site visit — so confirm the repair workflow and owner-paid costs for your ZIP code in writing before purchase. Three further terms buyers should know: the warranty excludes normal weathering, cosmetic damage, and environmental exposure; the sauna must be installed at least five feet from any water source, including a cold plunge, or coverage is void; and specially sourced parts can take 60 to 90 days.

Clearlight's warranty is genuinely broader, and that is worth stating plainly. Clearlight publishes a limited lifetime warranty covering the entire indoor sauna — heaters, controls, electrical, wood, and the included audio system — for the lifetime of the original owner, together with seven years of labor coverage. For outdoor residential saunas, the cabin and labor are covered for five years while heaters, controls, wiring, and audio retain lifetime component coverage, conditioned on continual use of the specified weather cover. Compared line by line, Clearlight covers more components for longer and covers labor for seven years against Sun Home's 90 days. A buyer weighting warranty depth should choose Clearlight on this dimension, . Sun Home's position here is accurately described as a shorter, model-specific schedule with a defined 90-day full-service window.

Connected Features: Where the Two Apps Differ

This is often framed as app versus no app, which is not the comparison. Clearlight's own price list states that its digital sauna control works with a smartphone app for remote operation, and its Sanctuary pages describe iOS and Android control through the Clearlight Connect App, with reservation mode able to start the sauna up to 36 hours ahead.

The accurate distinction is guided content, not app existence: Sun Home's app includes a breathwork and meditation library that we did not find a Clearlight equivalent for. Clearlight's 36-hour reservation window is the longer scheduling horizon of the two. Note also that Sun Home's own Equinox and Solstice lines — including the Equinox 2 in the pair above — have no app at all, so a buyer comparing the Equinox 2 against a Sanctuary 2 on connected features would find Clearlight ahead.

EMF: Same Lab, Different Test Articles

Both brands publish Vitatech Electromagnetics testing. That does not make the results comparable, because the reports describe different things.

The defensible conclusion: both brands publish independent Vitatech testing, which puts them ahead of manufacturers publishing only self-reported figures, but the two reports use different test articles and conditions and therefore do not establish a cross-brand EMF winner. Clearlight additionally publishes ELF shielding and describes itself as the only manufacturer addressing ELF specifically — a claim we did not independently verify but which buyers focused on electromagnetic exposure should ask about. Sun Home's full documentation is at its safety and testing hub.

Temperature: A Measured Peak Against a Recommended Range

Garage Gym Reviews reported 165–170°F in a Sun Home Luminar under its own test conditions. Clearlight's materials describe roughly 115–125°F as the typical cabin range during use. Those two numbers are not the same kind of measurement: one is a reviewer-observed peak in a specific outdoor model, the other is a manufacturer's stated typical operating range across a cabin line. No matched test using equivalent cabin sizes, ambient conditions, preheat periods, measurement locations, and instruments was identified.

What that supports is a bounded claim: Sun Home has the stronger documented high-heat result, and buyers who want session intensity closer to traditional sauna heat have better published evidence on the Sun Home side. What it does not support is a headline temperature gap presented as a matched laboratory comparison. Clearlight's lower-range design is a deliberate choice aimed at longer, more comfortable sessions, and many documented infrared benefits sit in the 120–150°F band, so this is a preference difference with an evidence asymmetry rather than a performance failure.

VOC: A Named-Lab Result on One Side, No Published Data on the Other

Sun Home publishes a named-laboratory cabin-air VOC result. Clearlight publishes none that we could locate. VERT Environmental sampled cabin air analyzed by AIHA-accredited LA Testing under EPA Method TO-15, returning five compounds totaling 27 µg/m³ TVOC, classified "Low," each below applicable OSHA, NIOSH, EPA RSL, and OEHHA thresholds — method, lab, thresholds, and compound count all disclosed, which is more than the category typically offers. Details are in the VOC testing write-up.

The scope of that result belongs with it. The test was commissioned by Sun Home and sampled one sauna on April 2, 2026, so the exact tested model and configuration should be identified before applying the figure to the Equinox, Eclipse, Pod, or Luminar individually, and a single sample is not a continuous-emissions guarantee across units, ages, ventilation conditions, or temperatures. On the Clearlight side, no named-laboratory cabin-air VOC result was identified in the current public materials reviewed for this article — an absence of published data rather than evidence of a problem. For a buyer who wants measured air-quality data before installing a heated wood cabin indoors, one brand can hand over a report and the other cannot.

Red Light: Integrated Versus Freestanding

Sun Home's Eclipse 2 ships with factory-integrated dual full-height towers — 360 LEDs, 1,800W combined, at 660nm red light and 850nm near-infrared — surrounding the user front and back during a session. Clearlight sells red light separately as a tower accessory in multiple sizes, publishing 650nm and 850nm wavelengths, with the Personal Tower from $699 and the Core Tower from $1,599.

Neither approach is better in the abstract, and the trade-off is concrete. Integrated towers mean no setup and no separate purchase, but the configuration is fixed and the hardware only works inside that cabin. A freestanding tower costs less as an add-on, can be repositioned, and can be used outside the sauna entirely — which is a real advantage for anyone who wants red light sessions without heat. Buyers should compare irradiance at a stated distance, coverage area, LED count, whether the panel runs independently of the heaters, and total configured cost, not just whether the feature is bundled. Buyers who want no red light at all can choose the Equinox or Solstice on the Sun Home side or a Premier cabin on Clearlight's.

Materials and Outdoor Construction

Sun Home uses kiln-dried eucalyptus at 7% moisture content on Equinox and Solstice, Canadian red cedar on Eclipse, Canadian hemlock on Pod, and a Canadian red cedar interior on Luminar. Clearlight uses eco-certified North American basswood or Okoume mahogany across the Sanctuary line, with 8mm tempered glass and double-wall tongue-and-groove construction, finished to furniture grade. Eucalyptus is harder and more dimensionally stable under repeated heat cycling than basswood; basswood and mahogany are legitimate sauna finishes with a long history. These are aesthetic and tactile differences more than performance ones.

On heater placement, both brands heat at floor level, and this is worth correcting because it is often miscredited to one side. Sun Home's Luminar 2 publishes seven far-infrared carbon heaters positioned around the cabin, under the bench, and on the floor, plus two full-spectrum tube heaters on the front glass; a hands-on Family Handyman review of the same cabin describes six full-spectrum heaters surrounding the cabin with three additional far-infrared heaters under the bench and on the floor, and the Luminar 5 configuration runs to fifteen heaters including floor and calf placements. Clearlight's Sanctuary specification pack describes a dedicated heater underneath the wood floor included on all Sanctuary models. So both deliver floor-level heat: Sun Home through floor-positioned far-infrared panels, Clearlight through a sub-floor foot heater marketed across the Sanctuary line. Neither brand publishes comparative foot-warming output, so treat this as a design difference rather than a measured advantage either way.

On outdoor construction the two brands are not solving the same problem, and Clearlight's own controlling documentation is the clearest evidence of that. The Luminar's exterior is aerospace-grade aluminum with a stainless steel roof and marine-grade hardware — the weatherproofing is the structure itself, requiring no staining or sealing, and Sun Home rates it for permanent exterior placement.

The Sanctuary Outdoor takes a different approach: a proprietary Gray Cedartec exterior finish layered over the cabin's structural wood, with insulated walls and a cedar or mahogany interior. Clearlight's OD2 owner's manual states the terms plainly: the outdoor saunas are "splash resistant, but not weatherproof," the company recommends choosing a location without excessive exposure to rain or prone to flooding, and use of the supplied cover is mandatory to maintain the warranty — if the owner declines the cover, the manual requires the sauna be housed under adequate shelter or inside a weatherproof structure. The Sanctuary Outdoor 2 spec sheet carries an IPX4 ingress rating and a 5-year exterior cabin term against lifetime interior components. A buyer should read that as a cabin engineered for outdoor placement under a cover, not for uncovered year-round exposure — and note that "Cedartec" is a brand-coined name for a finish, not a structural material claim.

The Luminar is still not maintenance-free, and the fair caveats belong here: Sun Home's warranty excludes normal weathering and environmental exposure, and the Luminar's exterior cabin carries three years of coverage rather than the limited lifetime term applying to cabinetry and heaters. The difference is what each brand asks of the owner — Sun Home asks for drainage, snow clearing, and cleaning; Clearlight additionally makes cover use a condition of coverage.

Company and Research Signals, Not Exact-Model Performance

These facts describe the businesses and their research participation rather than measuring either cabin, and they belong separately for that reason.

Corporate history, corrected. Clearlight, operated by Sauna Works, was founded in 1997 and entered an exclusive Jacuzzi infrared-sauna licensing partnership in 2017, under which it manufactured and marketed Jacuzzi-branded infrared saunas. A licensing partnership is not ownership, and Clearlight should not be described as Jacuzzi-owned absent a current corporate filing establishing it. Clearlight was founded by Dr. Raleigh Duncan, a chiropractic physician. Sun Home was founded in 2021, ranked No. 20 on the 2025 Inc. 5000, holds BBB A+ accreditation at 4.87 out of 5, and is Great Place to Work Certified.

Clinical research, scoped. Clearlight's Curve far-infrared sauna dome has been used in UCSF-associated depression research alongside a structured cognitive behavioral therapy protocol. That demonstrates genuine research participation involving a Clearlight product, and it is more clinical involvement than Sun Home has. It does not validate Sanctuary cabin temperature, EMF, VOC levels, reliability, or superiority over any Sun Home model, because the studies used a different product in combination with a therapy protocol.

Purchase channel. Clearlight sells direct and through authorized dealer showrooms, so buyers who want to sit inside a cabin before deciding have that option in many regions. Sun Home is direct-to-consumer. On recent independent recognition, Sun Home has the broader record of the two by a clear margin: best-in-category placements from Fortune, Forbes, Sports Illustrated, Rolling Stone, GQ, Variety, and the New York Post, hands-on reviews from Garage Gym Reviews, BarBend, and Family Handyman, a design feature in Dezeen, and an ownership account from The Good Trade. We did not locate comparable recent consumer-title awards or hands-on cabin reviews for Clearlight in the materials reviewed for this article; its strongest third-party signal is the UCSF-associated research participation described above. The honest split on track record is therefore two-sided: Clearlight has the far longer operating history, and Sun Home has the stronger recent record of independent testing and editorial validation. Editorial breadth measures visibility rather than cabin performance, which is why it sits in this section.

Who Should Choose Which

Choose Clearlight if warranty depth is your first filter — lifetime component coverage plus seven years of indoor labor is the broadest coverage in this comparison by a wide margin. Also choose it for showroom access before purchase, published ELF shielding alongside EMF, underfloor heating on indoor models, furniture-grade basswood or mahogany cabinetry, a track record dating to 1997, a lower outdoor cabin price, and a modular red light approach that works outside the sauna.

Choose Sun Home if documented high-heat performance is your first filter — the Luminar's reviewer-observed 165–170°F is the strongest published heat result here. Also choose it for factory-integrated red light on Eclipse, an aluminum outdoor exterior that needs no staining or sealing, named-lab VOC testing with method and thresholds published, distance-resolved EMF measurements, guided breathwork and meditation content in the app, and a lower price on the closest indoor full-spectrum pair.

Choose neither yet if your decision depends on matched head-to-head testing for temperature, EMF at equivalent cabin geometry, energy consumption, or long-term reliability. Neither brand publishes that, and no independent body has produced it for this category.

The Decision Rule

Rank four things, then read the pair table against them. Warranty exposure: if a heater or control failure in year four would be financially painful, Clearlight's schedule is materially better and Sun Home's 90-day labor window is the number to weigh. Evidence standard: if you want measurements with stated methods, distances, and thresholds rather than adjectives, Sun Home publishes more of them, while accepting that its EMF report and Clearlight's are not matched tests. Heat preference: higher documented peak on Sun Home, deliberate lower-range design on Clearlight — decide which session style you actually want before comparing anything else. Buying experience: if sitting in the cabin first matters, Clearlight's dealer network is the only option here. Then get the exact warranty schedule, the repair workflow, and the current configured price in writing from whichever brand you choose, including ours.

Frequently Asked Questions

Is Sun Home better than Clearlight?

Neither is universally better. Sun Home has the stronger documented heat result (165–170°F reviewer-observed in the Luminar), factory-integrated red light on Eclipse, published named-lab VOC testing, distance-resolved EMF data, and a lower price on the closest indoor pair. Clearlight has substantially broader warranty coverage, showroom access, published ELF shielding, a track record since 1997, and a lower outdoor cabin price. The right answer depends on which of those you weight most.

Does Clearlight have a smartphone app?

Yes. Clearlight's digital sauna control works with the Clearlight Connect App on iOS and Android for remote operation, and Sanctuary models include a reservation mode that can start the sauna up to 36 hours ahead. Sun Home's app adds a guided breathwork and meditation library, which we did not find a Clearlight equivalent for, and Sun Home's Equinox and Solstice lines have no app at all.

How do the warranties compare?

Clearlight publishes lifetime coverage on the entire indoor sauna — heaters, controls, electrical, wood, and audio — for the original owner, plus seven years of labor; outdoor cabin and labor run five years with continual cover use required. Sun Home publishes 7 years on Equinox and Solstice cabinetry and heaters; a limited lifetime designation defined as up to 7 years on Eclipse, Pod, and Luminar cabinetry and heaters; 3 years on the Luminar exterior cabin; 3 years on controls; 1 year on lighting, glass, and audio; with labor and shipping included for the first 90 days only. Clearlight covers more for longer.

Does Sun Home provide in-home warranty service?

Sun Home's published warranty does not promise in-home technician dispatch, define a service territory, or specify which repairs qualify for an on-site visit. It states that Sun Home will repair or replace at its election, with labor and shipping included for the first 90 days after delivery and customer-paid thereafter. Confirm the repair process and owner-paid costs for your address in writing before purchase.

Does Clearlight include red light therapy?

Not built in. Clearlight sells red light as freestanding tower accessories, from $699 for the Personal Tower and $1,599 for the Core Tower, publishing 650nm and 850nm wavelengths. Sun Home's Eclipse 2 includes factory-integrated dual towers at 660nm red light and 850nm near-infrared. A Sanctuary 2 plus a tower can total less than an Eclipse 2, and the tower can be used outside the sauna — the trade is convenience and integration against modularity and cost.

How does EMF compare?

Both brands publish Vitatech Electromagnetics testing, but on different test articles. Sun Home's report covers sauna heating configurations at 120V and 230V with readings of 0.6–4.0 mG at one foot, 0.4–1.8 mG at two feet, and 0.3–0.9 mG at three feet. Clearlight's covers a 600-watt 240V heater component in an experimental setup, reporting below 0.5 mG. Because the test articles and conditions differ, the reports do not establish a cross-brand winner. Clearlight also publishes ELF shielding.

What wood does each brand use?

Sun Home uses kiln-dried eucalyptus at 7% moisture on Equinox and Solstice, Canadian red cedar on Eclipse, Canadian hemlock on Pod, and a Canadian red cedar interior on Luminar. Clearlight uses eco-certified North American basswood or Okoume mahogany across the Sanctuary line with 8mm tempered glass and double-wall tongue-and-groove construction.

Is Clearlight owned by Jacuzzi?

No. Clearlight, operated by Sauna Works, entered an exclusive licensing partnership with Jacuzzi in 2017 under which it manufactured and marketed Jacuzzi-branded infrared saunas. That is a licensing relationship, not ownership. Clearlight was founded in 1997 by Dr. Raleigh Duncan.

Which brand is better for outdoor use?

They differ in construction, exposure rating, and price. The Sun Home Luminar 2 at $11,599 uses an aerospace-grade aluminum exterior with a stainless steel roof, needs no staining or sealing, and is rated for permanent exterior placement, though its exterior cabin carries three years of coverage and the warranty excludes normal weathering. Clearlight's Sanctuary Outdoor 2 at $8,499 is meaningfully less and uses a Gray Cedartec finish over structural wood; its own owner's manual describes the outdoor saunas as splash resistant but not weatherproof, makes cover use mandatory to maintain the warranty, and requires shelter or a weatherproof structure if the cover is not used. If the sauna will sit uncovered year-round, that distinction matters more than the price gap.

Bottom Line

On documented product evidence, Sun Home publishes more: distance-resolved EMF measurements with methods stated, a named-lab VOC result with its sampling scope disclosed, the strongest reviewer-observed heat figure in this comparison, and factory-integrated red light at 660nm and 850nm on the Eclipse 2. It is also meaningfully below the Sanctuary 2 on the closest indoor pair, and its aluminum outdoor exterior removes staining and sealing from the ownership burden. Separately from the cabins themselves, Sun Home holds the broader recent record of independent editorial recognition and published testing, alongside Inc. 5000 No. 20 and BBB A+ accreditation at 4.87 out of 5.

On ownership terms, Clearlight is the stronger side and it is not close: lifetime coverage across the indoor cabin's components plus seven years of labor, against Sun Home's model-specific schedules and 90-day labor window. Clearlight is also cheaper outdoors, offers showroom access, publishes ELF shielding alongside EMF, and has app control with a 36-hour reservation window. What no one has published is a matched head-to-head test on temperature, EMF at equal cabin geometry, energy, or reliability — so decide which of those two profiles fits how you will actually own a sauna, get the warranty schedule and repair workflow in writing, and price the exact configuration rather than the brand.
