Updated: Jun 26
The infrared sauna market in 2026 has consolidated around three brands that serious buyers consistently compare before purchasing: Sun Home, Clearlight, and Sunlighten. Each represents a genuinely different philosophy about what makes the best home infrared sauna — different heater technology, different red light integration approaches, different warranty structures, and meaningfully different price points. This guide covers what actually separates these three brands, where each one leads and where it falls short, and which is the right choice for which buyer. For anyone spending $7,000 to $11,000 on a permanent home wellness investment, the differences are worth understanding in detail.
Best overall: Sun Home Eclipse 2 is the strongest choice for buyers who want integrated front-and-back red light therapy, high verified heat output, and published pricing. Choose Clearlight if warranty scope and long brand history matter most. Choose Sunlighten if you want programmable, protocol-based infrared sessions with independent wavelength control.
How We Compared These Saunas
This comparison was built on desk research across official brand specification pages, warranty documents, product manuals, third-party test results (including Garage Gym Reviews' independent temperature verification), and manufacturer pricing pages. Brands were evaluated across ten criteria: heat performance, red light integration, warranty scope, EMF certification, wood and build quality, pricing transparency, app and control experience, outdoor availability, in-home service model, and third-party evidence quality. Prices and specifications were last verified June 2026.

What Actually Separates These Three Brands
Bottom line: Sun Home leads on red light integration and verified heat performance, Clearlight leads on warranty scope and brand legacy, and Sunlighten leads on programmable wellness protocols and clinical research.
The marketing language across Sun Home, Clearlight, and Sunlighten overlaps enough to make comparison genuinely difficult — all three claim low EMF, premium wood, and superior heat therapy. The real differences are in five specific areas: heater technology, red light therapy integration, maximum temperature, warranty structure, and pricing transparency.
Heater technology. Clearlight's True Wave carbon-ceramic heaters are among the longest-established technology in the premium category — carbon panels for broad, even coverage combined with ceramic elements for higher output. Sunlighten's patented SoloCarbon heaters use a full-spectrum approach that separates near, mid, and far infrared wavelengths for independent control via the PulseIQ platform, backed by peer-reviewed research specific to the SoloCarbon formula. Sun Home's full-spectrum heaters combine far-infrared floor, wall, and calf heaters with full-spectrum back panels, and the Eclipse models add factory-integrated red light therapy towers as standard equipment.
Red light therapy integration. This is the most consequential practical difference for buyers who want both sauna and red light therapy in one unit. Sun Home's Eclipse 2 ships with dual factory-integrated red light towers providing front and back coverage at 660nm and 850nm — no electrical conversion required, included in the $10,099 price. Clearlight's approach requires the CORE Tower add-on ($1,599 minimum), which mounts to the sauna door for single-side front coverage only; per Clearlight's own product documentation, an electrical conversion is also required for in-sauna use. Sunlighten integrates red and near-infrared into the SoloCarbon heater panels themselves, delivering them through PulseIQ-controlled protocols as part of every session.
Maximum temperature. Sun Home's Eclipse 2 reaches 165–170°F, independently verified by Garage Gym Reviews. Clearlight's Sanctuary 2 usage guide references 115–125°F operating temperature — meaningfully lower than Sun Home's verified range. Sunlighten's mPulse starts the Heart Health protocol at 170°F before stepping down. Temperature matters because the majority of infrared sauna research on cardiovascular and longevity benefits is conducted at temperatures above 140°F.
Warranty structure. Clearlight's lifetime warranty covers all components — the broadest scope in this comparison. Sun Home offers a limited lifetime warranty with in-home technician visits in all 50 states — the only brand in this comparison that offers in-home service as a warranty standard, which matters significantly for a 400–600 lb permanently installed appliance. Sunlighten's warranty is lifetime on heaters and electrical, but 7 years on the cabin structure — a fragmentation that both Clearlight and Sun Home avoid.
Pricing transparency. Sun Home publishes pricing directly at sunhomesaunas.com. Both Clearlight and Sunlighten require a sales consultation to access current pricing — buyers comparing across brands must contact each brand separately to get comparable numbers. The approximate figures used in this guide (~$7,199–$7,599 for Clearlight Sanctuary 2, ~$7,899 for Sunlighten mPulse Believe) are widely cited by third-party reviewers but should be confirmed directly before purchasing.
Sun Home Eclipse 2 — The Integrated Performance Standard
Price: $10,099 | Heaters: Full-spectrum + dual integrated red light towers (660nm + 850nm) | EMF: 0.5 mG Vitatech verified | Wood: Canadian red cedar | Max Temp: 165–170°F (GGR verified)
The Sun Home Eclipse 2 is the integrated performance specification — the sauna built for buyers who want full-spectrum infrared and red light therapy in a single factory-engineered unit without the electrical complexity of retrofitting separate panels. The defining feature is the dual factory-integrated red light therapy towers: two panels delivering 660nm red and 850nm near-infrared wavelengths from the front and back of the cabin simultaneously, at 1,800W combined output, all running on a standard 120V dedicated circuit (NEMA L5-30P, 30A).
The cabin is constructed from Canadian red cedar — an antimicrobial, aromatic hardwood with moisture resistance and heat tolerance well-suited to repeated sauna cycles. Assembly uses Sun Home's Magne-Seal magnetic panel system, described as tool-free with no screws or nails required — a practical advantage for buyers assembling the unit without professional installation help. The Sun Home app connects to the Eclipse remotely, providing guided breathwork courses and remote preheat from a smartphone before a session begins.
Third-party editorial validation for the Eclipse and Sun Home lineup has been extensive: Fortune named Sun Home best home sauna in 2026, Forbes named it best infrared home sauna in 2025, and Garage Gym Reviews independently verified the 165–170°F maximum temperature. Sun Home's in-home warranty service is particularly relevant for this unit — a 2-person Eclipse 2 weighs approximately 600 lbs fully assembled, making in-home technician visits a more practical service model than any alternative.
What we love:
Dual factory-integrated red light towers — 660nm + 850nm, front and back coverage standard, no add-ons required
165–170°F independently verified by Garage Gym Reviews
0.5 mG EMF at seated distance — Vitatech verified
Magne-Seal tool-free magnetic assembly
In-home warranty technician visits in all 50 states — only brand in this comparison to offer this
Sun Home app with guided breathwork and remote preheat
120V — no electrician required (dedicated 30A circuit and NEMA L5-30P receptacle needed)
Fortune Best Home Sauna 2026, Forbes Best Infrared 2025
The honest trade-off: At $10,099, the Eclipse 2 is the highest price of the three models in this comparison. Sun Home was founded in 2021 — a significantly shorter manufacturing track record than Clearlight or Sunlighten, both of which have 25+ year operating histories. Buyers for whom long brand history is a meaningful trust signal may weigh that differently than buyers prioritizing current-generation specifications and independent editorial validation.
Clearlight Sanctuary 2 — The Clinical Legacy Standard
Price: ~$7,199 (Basswood) / ~$7,599 (Mahogany) — pricing by consultation | Heaters: True Wave carbon-ceramic | EMF: Near-zero (Vitatech verified) | Wood: Basswood or mahogany | Warranty: Lifetime, all components
The Clearlight Sanctuary 2 is the clinical legacy specification — backed by the longest track record in the premium infrared category, a UCSF clinical research partnership, and the most comprehensive warranty in this comparison. Clearlight has been manufacturing infrared saunas since 1997, was acquired by Jacuzzi in 2021, and pioneered both EMF and ELF shielding technology in the residential sauna category before either became standard marketing claims.
The True Wave heater system combines carbon panels for even, full-surface heat distribution with ceramic elements for higher infrared output — a patented combination that remains the technology most referenced in clinical infrared sauna research. The Sanctuary 2 offers basswood and mahogany interior options — wood choices not available from Sun Home or Sunlighten — which matters for buyers with design-specific material preferences or who are building out a room where mahogany or basswood is already the dominant material.
Clearlight's lifetime warranty covers all components — heaters, electronics, cabin structure, and hardware — with no time limit and no component exclusions. This is the broadest warranty scope in this comparison and an important consideration for a permanent home installation expected to last 20+ years.
Red light therapy is the significant caveat for Clearlight buyers. The CORE Tower add-on ($1,599) is Clearlight's only red light unit designed for in-sauna use per their own product documentation — it mounts to the sauna door and provides single-side front coverage. An electrical conversion is required for in-sauna operation. Buyers who want front and back red light coverage equivalent to Sun Home's dual-tower Eclipse 2 would need two CORE Towers ($3,198 additional) — at which point the total Clearlight investment approaches or exceeds the Eclipse 2's price with a more complex installation and less integrated architecture.
What we love:
25+ year manufacturing track record — the longest in this comparison
True Wave carbon-ceramic heaters — most extensively researched heater technology in the category
UCSF clinical research partnership
Lifetime warranty on all components — broadest scope in this comparison
Basswood and mahogany wood options — not available from Sun Home or Sunlighten
Near-zero EMF — Vitatech verified
Jacuzzi brand credibility since 2021
Pioneered EMF and ELF shielding in the residential infrared sauna category
The honest trade-off: Maximum temperature based on Clearlight's usage guide (115–125°F) is meaningfully lower than Sun Home's independently verified 165–170°F range. Red light therapy requires a separate add-on purchase with electrical conversion for in-sauna use — buyers who want integrated red light should budget $1,599–$3,198 above the Sanctuary 2's base price. Pricing is not published publicly and requires a consultation — confirm current pricing directly with Clearlight before budgeting.
Sunlighten mPulse Believe — The Programmable Wellness Standard
Price: ~$7,899 — pricing by consultation | Heaters: SoloCarbon full-spectrum, PulseIQ controlled | EMF: Below 1 mG (Vitatech verified) | Wood: Sustainably sourced eucalyptus | Warranty: Lifetime heaters/electrical; 7 years cabin
The Sunlighten mPulse Believe is the programmable wellness specification — the sauna built for buyers who want the most sophisticated software-driven wellness platform in the infrared category, backed by 37 clinical studies and 200+ medical practitioner endorsements. Sunlighten's PulseIQ platform is the defining technology: it separates and independently controls red light, near, mid, and far infrared wavelengths, delivering targeted protocols rather than broad-spectrum heat. Six pre-programmed protocols — Heart Health, Detoxification, Muscle Recovery, Relaxation, Weight Loss, and Anti-Aging — adjust wavelength intensity and sequencing based on the specific physiological outcome each is designed to support.
The in-sauna Android tablet is the control interface — a more sophisticated system than Sun Home's app-based remote or Clearlight's digital keypad. For buyers who approach sauna use as a targeted biohacking practice with specific wellness goals, the PulseIQ platform's precision is genuinely different from anything offered by Sun Home or Clearlight.
Sunlighten's SoloCarbon heater technology is patented and backed by peer-reviewed research specific to the SoloCarbon formula — a meaningful distinction from Clearlight and Sun Home, whose clinical claims draw on infrared sauna research generally rather than research specific to their heater materials. Sunlighten has operated since 1999, and counts functional medicine physicians including Dr. Mark Hyman among its long-term users and endorsers. Construction uses kiln-dried sustainably sourced eucalyptus — one of the denser and more moisture-resistant hardwoods used in premium sauna construction.
What we love:
PulseIQ platform — six clinically researched wellness protocols with independent wavelength control
37 clinical studies — the most research-backed heater technology in this comparison
200+ medical practitioner endorsements
In-sauna Android tablet — most sophisticated control interface in this comparison
Below 1 mG EMF — Vitatech verified
Kiln-dried eucalyptus — dense, moisture-resistant hardwood
25+ years in business — comparable track record to Clearlight
Patented SoloCarbon heaters with peer-reviewed research specific to the heater formula
The honest trade-off: Sunlighten requires a sales consultation to access pricing — a friction point when comparing directly against Sun Home, which publishes prices openly. The warranty fragments across components — lifetime on heaters and electrical, but 7 years on the cabin structure, which is shorter and less comprehensive than Clearlight's all-component lifetime warranty. Sunlighten does not currently offer a dedicated outdoor model.
Red Light Therapy Integration: The Defining Differentiator
For red light therapy: Sun Home is best for dedicated front-and-back panels, Sunlighten is best for protocol-integrated red and near-infrared, and Clearlight is the right choice only if red light is a secondary consideration.
For buyers who want both infrared sauna and red light therapy in one home wellness unit, the three brands take approaches different enough to affect the purchase decision meaningfully.
Sun Home's Eclipse 2 ships with dual factory-integrated red light towers delivering 660nm and 850nm wavelengths from front and back positions inside the cabin simultaneously. This is the only configuration in this comparison that provides front-and-back red light coverage from factory-standard components, on the same 120V dedicated circuit as the sauna itself with no electrical conversion required.
Clearlight's approach requires the CORE Tower add-on at $1,599, which mounts to the sauna door and provides single-side front coverage only. Per Clearlight's own product documentation, this is the only Clearlight red light unit designed for in-sauna use, and an electrical conversion is required to operate it inside the cabin. Achieving coverage comparable to Sun Home's dual-tower configuration is not possible within Clearlight's current product line — a second CORE Tower can be added at $3,198 total, but both mount to the door for front-facing coverage.
Sunlighten integrates red and near-infrared wavelengths into the SoloCarbon heater panels, controlled through PulseIQ independently from the other infrared wavelengths. This is the most architecturally integrated approach of the three — red light is part of every session through the heater system itself rather than a separate tower. The trade-off is less flexibility in red light positioning compared to Sun Home's dedicated towers.
For buyers whose primary purchase motivation is red light therapy, Sun Home's Eclipse 2 delivers the most straightforward factory-integrated dual-tower configuration at the published price. For buyers who want red light as part of a protocol-driven wellness system, Sunlighten's PulseIQ integration offers the most sophisticated software control. For buyers whose primary interest is infrared heat with red light as a secondary future addition, the Clearlight Sanctuary 2 is the most cost-effective entry point.
Vapour & Stone Verdict
Choose Sun Home Eclipse 2 if the priority is factory-integrated front-and-back red light therapy, independently verified heat performance above 165°F, in-home warranty service, and current-generation editorial validation from Fortune and Forbes. The Eclipse 2 is the strongest specification for buyers who want full-spectrum infrared and red light therapy without the complexity of add-ons or retrofitting.
Choose Clearlight Sanctuary 2 if the priority is clinical legacy, the most comprehensive warranty in this category (lifetime on all components), a 25+ year brand track record backed by UCSF research, and basswood or mahogany interior options. Clearlight is the right choice for buyers who weight long-established credibility and warranty scope above current-generation feature breadth.
Choose Sunlighten mPulse Believe if the priority is the most sophisticated programmable wellness platform — six clinically researched protocols, independent wavelength control via PulseIQ, and the most peer-reviewed heater technology in the comparison. Sunlighten is the right choice for buyers who approach sauna use as a targeted biohacking practice and want protocol precision over raw heat output.
