Sun Home vs Peak Saunas Matterhorn: Full-Spectrum Infrared Comparison

Published May 7, 2026

Updated August 6, 2026. Every price, specification, warranty term, and evidence citation in this comparison was verified against current manufacturer pages on August 6, 2026.

Direct Answer

The best Peak Saunas Matterhorn alternatives are the Sun Home Equinox 3 for lower price, higher published heat, and simpler 120V installation, and the Sun Home Eclipse 4 for integrated red light, four-person capacity, and one native app. The Matterhorn is the option in this comparison for buyers who specifically want a compact cedar cabin with factory red light; its optical figures — like every performance number on its pages — are manufacturer-stated, and no independent report verifies them.[1]

No model is a perfect one-to-one substitute. At prices verified August 6, 2026, the Equinox 3 ($6,999)[6] costs $3,751 less than the Matterhorn ($10,750)[1] but has no integrated red light or app. The Eclipse 4 ($12,999)[7] costs $2,249 more and requires its own dedicated 240V/30A circuit, but adds four-person capacity, two integrated red-light towers, and Sun Home's native app. The right choice depends on whether the buyer prioritizes heat and value, integrated red light and capacity, or compact size and published optical detail.

The Matterhorn's most consequential problems are ownership-documentation consistency and exact-model verification: Peak's current pages publish materially conflicting warranty terms[1] and Wellness Club pricing,[3] its remote control depends on two separate apps,[4] its own pages disagree on the heater count,[1] its halogen/quartz full-spectrum emitters — the hardware behind its near- and mid-infrared claim — appear side-wall-mounted in Peak's own product photography rather than facing the seated body,[1] and no independent exact-Matterhorn thermal, EMF, cabin-air, or optical report was identified on the pages reviewed. Every performance figure remains manufacturer-stated.

Disclosure: Sun Home Saunas publishes this comparison and manufactures the Equinox 3 and Eclipse 4. Every material claim is tied to an identified source, manufacturer-stated figures are labeled as such, and inferences, absence findings, owner feedback, and brand-level evidence are distinguished from exact-model verification. Peak's documented strengths are stated alongside its limitations. Nothing in this article is medical advice; this guide compares hardware, documentation, and ownership terms, not health outcomes.

How we selected these alternatives: We compared currently sold models on listed capacity, interior dimensions, heating system, stated maximum temperature, integrated red light, price, electrical requirements, controls, warranty, return terms, and the scope of independent documentation. Because no Sun Home model matches both the Matterhorn's compact three-person footprint and integrated red light, this guide identifies one alternative for capacity, heat, and value and another for integrated red light and larger capacity.

Quick Picks

  • Best three-person value for higher published heat and lower installation burden: Sun Home Equinox 3 — $7,699, 120V/20A, 165°F manufacturer-stated maximum.[6]
  • Best for integrated red light, four-person capacity, one native app, and named-laboratory brand safety documentation: Sun Home Eclipse 4 — $13,599, 240V/30A, dual towers with published wavelengths, LED count, and panel ratings.[7]
  • Publishes irradiance figures for its integrated panels: Peak Saunas Matterhorn — manufacturer-stated figures at 6, 12, and 24 inches, with no independent optical verification identified. Irradiance disclosure is not unique to Peak: Sun Home publishes irradiance for its Luminar red light panel.[12]
  • Lowest price for factory-integrated red light in this comparison: Peak Saunas Matterhorn — $10,750, 61-inch-wide footprint, subject to the warranty, subscription, and return-term conflicts detailed below.
  • Same Matterhorn hardware for $1,000 less: the hemlock Peak Denali — Peak states the heaters, red-light hardware, footprint, warranty, and features are identical, and only the wood differs.

What Peak's Pages Publish — Stated Accurately

Peak positions the Matterhorn as full-spectrum infrared with included red light at a direct-to-consumer price. Its current product page publishes: a $10,750 price; electrical requirements (240V/20A, 2,850W, NEMA 6-20P, dedicated circuit with an electrician recommended); eight heating panels (carbon far-infrared plus halogen/quartz emitters); a 150°F stated maximum; interior and exterior dimensions and weight; a downloadable CAD drawing and owner's manual; and a red-light specification listing two 9" × 36" panels, 216 dual-chip LEDs per panel, a 30-degree beam angle, eight wavelengths (630, 650, 660, 670, 810, 830, 850, and 1,060 nm), and irradiance figures at three distances (175 mW/cm² at 6", 107 at 12", 80 at 24") — all manufacturer-published, none independently verified.[1] Peak Wellness USA holds BBB accreditation with an A+ rating, accredited since March 28, 2024.

Stating this accurately matters for two reasons. First, older criticisms that Peak fails to publish electrical requirements, wavelengths, LED counts, or irradiance no longer match its current pages, and this guide does not make them. Second, publishing a number is not the same as verifying one — and the questions that decide real ownership sit one level deeper: whether Peak's ownership documents agree with each other, and whether any performance claim has been independently checked at the exact-model level. That is where the rest of this comparison concentrates.

Head-to-Head 1: Matterhorn vs Equinox 3 — Capacity and Heat

This is the proper apples-to-apples matchup on capacity: both are listed three-person cabins with nearly identical interior widths (57" vs 56.8"). The differences that matter:

Price and installation. The Matterhorn costs $3,751 more than the Equinox 3 at verified August 6 pricing, and it requires a dedicated 240V circuit that Peak itself says needs an electrician. The Equinox 3 runs on a 120V/20A dedicated circuit with a standard NEMA 5-20P plug — if a 20A receptacle already exists at the installation location, it plugs straight in; if not, adding one is a smaller electrical job than a new 240V run in most homes. See our sauna electrical requirements guide for specifics.

Heat documentation. Peak publishes a 150°F maximum and markets it as hotter than models capped at 140°F; no independent measurement of that figure was identified. The Equinox line publishes a 165°F maximum, and Garage Gym Reviews independently reported 165°F during extended hands-on use of the two-person Equinox (the publication did not release a complete measurement protocol, and the measurement was of the two-person model, so for the Equinox 3 it is product-line editorial evidence rather than an exact-model test). No independent Matterhorn temperature measurement was identified. On published figures, the Equinox line's stated ceiling is 15 degrees higher.

What the Matterhorn's $3,751 premium pays for. Two integrated red-light panels (specifications manufacturer-published, not independently verified), phone control, an oxygen ionizer, a foot-reflexology heater, and cedar construction — alongside the documentation conflicts detailed below. The Equinox 3 has none of those features — its feature set is onboard reservation-mode controls, Blaupunkt Bluetooth audio, chromotherapy, and Magne-Seal tool-free assembly. Buyers who specifically want integrated red light should not treat the Equinox 3 as a substitute; the honest comparison for that buyer is the Eclipse 4 below, or the Matterhorn itself.

Head-to-Head 2: Matterhorn vs Eclipse 4 — Integrated Red Light and Capacity

For a buyer who wants infrared heat plus factory-integrated red light in one cabin, these are the two relevant models — and neither dominates the other.

What the Matterhorn's page lists that the Eclipse 4's does not. A $2,249 lower price, a smaller footprint (61" wide versus 94.4"), and additional optical figures: irradiance at three distances, a beam angle, and eight wavelengths against the Eclipse's two — all manufacturer-stated, with no independent optical report identified. On integrated-panel irradiance, the Matterhorn lists figures and the Eclipse 4 does not — but the disclosure is not Peak-exclusive: Sun Home publishes irradiance for its Luminar red light panel (140 mW/cm² at 6 inches and 110 mW/cm² at 12 inches, with 90 red and 90 near-infrared LEDs at a 30-degree angle), an add-on made for the Luminar sauna line.[12] Every irradiance figure from either brand is manufacturer-stated.

Where the Eclipse 4 leads. It is a genuine four-person cabin with 16 published heaters — 12 far-infrared plus 4 full-spectrum on the back wall, positioned behind and directed at the seated body — a 165°F stated maximum versus 150°F, two full-height red-light towers (360 LEDs total, 650 nm and 850 nm, a published 900W rating per panel), the native brand-owned Sun Home app with scheduling and guided breathwork, tool-free Magne-Seal assembly, and Sun Home's named-laboratory brand documentation behind it. Its warranty structure is also fully published in one governing document, including the 90-day labor-and-freight terms.

What neither publishes. Independent optical verification. Peak's irradiance figures and Sun Home's panel ratings are both manufacturer-published; no third-party spectrometer report, uniformity map, or exact-model optical test was identified for either sauna, and Sun Home's documentation does not define whether the 900W panel rating reflects electrical input or emitted optical power. Both brands describe their LEDs as medical-grade; in both cases that is manufacturer terminology rather than a regulatory classification — Peak's own EMF page states its products are wellness products, not medical devices. Buyers comparing red-light claims should treat every optical number from either brand as manufacturer-stated until an independent report exists. Browse the red light sauna collection for the full Sun Home RLT lineup.

The Warranty Documentation Problem

This is the Matterhorn's most consequential weakness, and it is visible on a single page. The governing warranty table on Peak's own Matterhorn product page provides: heating elements and cabinetry "lifetime," with lifetime expressly defined as 7 years under normal residential use; control system and power supply 3 years; chromotherapy lighting, sound system, accessories, and WiFi/app connectivity 1 year each; labor and technician fees not covered; replacement-parts freight customer-paid after 90 days; non-transferable; and claim qualification determined at Peak's discretion, with photo or video evidence sometimes required.[1] Yet the marketing sections of the same page — and other current Peak pages — present "FREE Lifetime Warranty" and describe every component as covered for life, and Peak's other published materials have listed different red-light-panel and labor terms. A buyer cannot confidently determine from Peak's site whether the two red-light panels receive one, two, or seven years, or which document controls when the marketing page conflicts with the warranty table.

The evidence-safe conclusion: Peak publishes materially conflicting warranty terms across its current website, so buyers should obtain the exact Matterhorn component schedule in writing before purchase.[1][4] That is a documentation-consistency problem, not proof of bad hardware — but warranty terms directly determine real ownership cost, and they need one source of truth.

Sun Home's terms, stated exactly from the single governing warranty document (orders on or after March 2, 2026): the Eclipse 4 carries limited lifetime coverage on cabinetry and heaters (defined as up to seven years), 3 years on controls, 1 year on LED lighting, glass, and audio, with parts, labor, and shipping included for the first 90 days and labor and shipping customer-paid afterward. The Equinox 3 carries 7 years on cabinetry and heaters, 3 years on controls, and 1 year on glass and audio, with labor and freight terms not stated in the current primary Equinox/Solstice block — confirm those at purchase.[8] Both brands define core "lifetime" coverage as seven years, both exclude labor outside a defined window, and both warranties are non-transferable; neither contractually guarantees nationwide in-home technician dispatch. The difference is not that one warranty is generous and the other is not — it is that Sun Home's terms live in one governing document while Peak's current pages disagree with each other. Get any brand's component schedule in writing.

Peak Wellness Club: Free for Life, or $49 a Month?

The Matterhorn page includes a lifetime Peak Wellness Club membership and assigns it a $588-per-year value — a benefit Peak uses to help justify the purchase price. Other current Peak pages describe the same platform as a 60-day free trial followed by a $49 monthly subscription with optional cancellation.[1][3] Those two published versions are mutually exclusive, and because the claimed value is $588 annually, the difference materially affects the Matterhorn's advertised value proposition. Before purchase, a buyer should get in writing: whether the order includes lifetime access; whether the price can change later; whether payment information is required; which software features — including sauna and red-light controls — remain operational if a membership ends; and whether the free-for-life promise attaches to the owner, the device, or the account.

The App Experience Is Split Across Two Systems

The Matterhorn product page presents one Peak app handling remote start, scheduling, temperature, lighting, and session length. Peak's help documentation describes a different architecture: Smart Life — a third-party smart-home platform — controls the sauna's heat, while a separate Peak red-light app controls the panels.[4] That does not mean the Matterhorn lacks smart controls; the physical touchscreens work regardless, and phone control exists. It means the remote experience depends on two software systems, with the friction that implies: two setups, separate heat and light timers, and reliance on third-party infrastructure for the core heating function. A verified Matterhorn owner reported exactly this seam — one red-light panel shutting off at its default timer while the other kept running — and Peak responded that the panels can be grouped through the app, offering instructions.

On the Sun Home side, be equally precise: the Equinox 3 has no app at all — scheduling runs through its onboard reservation mode. The brand-owned native Sun Home app (remote operation, scheduling, guided breathwork) is an Eclipse, Pod, and Luminar feature, so in this comparison it applies to the Eclipse 4 only.

"Three-Person" Means Maximum, Not Comfortable Routine Use

The Matterhorn's 57-inch interior width works out to roughly 19 inches per person at its listed capacity of three. A verified Matterhorn owner described it as having plenty of space for two but said three would be snug — and noted, fairly, that most three-person saunas from most manufacturers share this reality. The honest read: the Matterhorn is best understood as a spacious two-person cabin that can seat three, rather than an equally comfortable three-person installation. The same distinction applies to the Equinox 3 at its nearly identical 56.8-inch width. One Matterhorn-specific wrinkle: its two red-light panels are mounted across the front wall, so with three occupants only two positions can sit approximately centered on a panel — an inference from the published layout, not a measured performance result, but worth knowing if three-person red-light sessions are the plan. Buyers who need comfortable capacity for three or more should look at four-person cabins like the Eclipse 4.

Where the Matterhorn's Near- and Mid-Infrared Heat Actually Comes From

The Matterhorn's full-spectrum claim rests on a hybrid system: carbon panels for far infrared plus halogen/quartz emitters for the near and mid bands. What the product page does not publish is where those emitters sit — there is no panel-position map, and Peak's own pages conflict on whether the cabin has eight panels or nine. Peak's product photography shows the halogen/quartz emitters mounted on the side wall behind wooden grilles; the hardware facing the seated occupants is the pair of LED red-light panels, and an LED light-therapy panel is not an infrared heat emitter.[1]

Why the placement matters: halogen and quartz emitters are directional, line-of-sight sources, and they are the hardware behind the near- and mid-infrared portion of the full-spectrum claim. Side-mounted, their output crosses the cabin at an angle toward the side of the nearest occupant rather than being directed at the front of the seated body — so the wavelengths aimed squarely at occupants come from the LED panels, which deliver light rather than sauna heat. The far-infrared carbon panels distributed around the cabin still provide general warmth; this is a question of which bands reach the body front-on, not whether the cabin gets hot. This assessment is based on Peak's published product photography — Peak publishes no seat-by-seat exposure data or panel-position documentation that would settle it, and buyers choosing the Matterhorn specifically for directed near- and mid-infrared exposure should ask Peak for emitter positions in writing. By contrast, the Eclipse 4 publishes its four full-spectrum heaters on the back wall — positioned directly behind, and directed at, the seated body — alongside its front-facing red-light towers.

What One Verified Matterhorn Owner Reported

The most useful Matterhorn-specific evidence available is a detailed verified-owner review published on Peak's own product page. The owner — satisfied overall and recommending the sauna — reported three design issues: insufficient clearance between the right red-light panel and the adjacent wall to operate its controls conveniently; the right and left panels behaving differently on their timers (the right defaulting to a roughly 15-minute shutoff); and the floor heater becoming uncomfortably hot above approximately 125–130°F, forcing him to shift his feet off the wooden cover. Peak acknowledged the feedback, offered panel-grouping instructions and floor-heater operating tips, and said the panel-positioning suggestion could inform engineering updates.[1] A second owner called assembly manageable but said the written instructions were not very good. This is one household's exact-model feedback, acknowledged by the manufacturer — no public data establishes how frequently these issues occur, and it should not be read as a defect rate. It is exactly the kind of granular, verifiable detail spec sheets don't capture.

Independent Verification: What Each Brand Can and Cannot Show

Peak. The Matterhorn's 150°F temperature, low-EMF positioning, air quality, and red-light output are all manufacturer-stated. No independent exact-Matterhorn thermal test, named EMF laboratory report, cabin-air VOC report, or third-party optical measurement was identified on the pages reviewed; Peak's own recent full-spectrum guide acknowledges that third-party-verified maximum-temperature figures are not yet published and that EMF and VOC reports were commissioned but not yet released, and its EMF page names no laboratory, instrument, distance grid, test date, or downloadable report.[5] Peak's current pages also disagree on a load-bearing spec: the Matterhorn product page lists eight heating panels while a current Peak guide describes nine (five carbon plus four halogen/quartz). None of this means the claims are false — it means a buyer cannot independently audit them at the exact-model level, and Peak should publish one canonical Matterhorn specification sheet.

Sun Home. The verification is real but must be scoped precisely. Garage Gym Reviews independently reported 165°F during hands-on use of the two-person Equinox, without publishing a complete measurement protocol.[10] Vitatech Electromagnetics (report VTE-3534, January 2025) published representative EMF ranges across tested 120V and 230V configurations — 0.6–4.0 mG at one foot, 0.4–1.8 mG at two feet, 0.3–0.9 mG at three feet; the frequently quoted 0.5 mG figure falls within the three-foot range and is not a universal exact-model reading. VERT Environmental collected a one-time cabin-air sample (April 2, 2026, Project #66958), analyzed by AIHA-accredited LA Testing under EPA Method TO-15 at 27 µg/m³ TVOC — one tested unit, model not publicly identified. Applied Technical Services analyzed the assembly adhesive (no formaldehyde or BTEX above reporting limits). Sun Home saunas are ETL Listed for the U.S. and Canada through Intertek, plus RoHS compliance. None of these documents is an exact-model Equinox 3 or Eclipse 4 test — they are brand-level, named-laboratory documentation, which is materially more than Peak currently publishes, and materially less than exact-model lab proof. Full reports are on the safety and testing page.[9]

One more evidence note. The Matterhorn page connects its 150°F heat to a widely cited Finnish study associating frequent sauna use with a 40% reduction in all-cause mortality. That research was an observational cohort of Finnish men using traditional saunas at roughly 176–194°F — an association, not a demonstration of causation, and not a study of any infrared cabin. It is legitimate background sauna research; it is not a Matterhorn outcome, and this guide makes no health-outcome claims for any model compared here.

Return Terms: What "Risk-Free" Costs in Practice

Peak's published return terms include a 25% restocking fee — $2,687.50 at the Matterhorn's current price — plus customer-paid return freight that Peak's own materials commonly estimate at $200 to $500, and repacking in the original crate; some Peak pages add disassembly requirements. A realistic Matterhorn return therefore approaches $2,900 to $3,200 before counting the labor of disassembling and re-crating a 400-pound cabin. Peak's current pages also conflict on whether an assembled or used sauna remains return-eligible at all: one invites owners to set it up and use it before deciding, while others require unused, unassembled, original-packaging condition.[1][2] Whatever brand you buy, get the return terms — eligibility, fees, freight responsibility, and condition requirements — in writing before ordering, and read them as part of the real price of trying the sauna.

The $1,000 Question: Matterhorn or Denali?

Peak states plainly that the Matterhorn and the hemlock Denali are the same sauna — identical heaters, full-spectrum and red-light hardware, footprint, warranty, and features — and that the only difference is the wood, with the Denali costing $1,000 less.[1] That means the Matterhorn's premium buys cedar aroma, appearance, and cedar's natural resistance properties, not more heat, better optics, more space, or better coverage terms. Buyers who do not specifically want cedar — or who are sensitive to its scent — should buy the Denali and keep the $1,000; buyers who love cedar are paying for exactly that, knowingly.

Bottom Line

The Matterhorn's spec sheet is long; its problems are documentation and verification: conflicting warranty schedules, mutually exclusive Wellness Club pricing, a split two-app control architecture presented as one, an eight-versus-nine heater-count conflict, side-wall-mounted near- and mid-infrared emitters per its own product photography, expensive and inconsistent return terms, and performance claims that remain entirely manufacturer-stated. Given that: choose the Equinox 3 if you want three-person full-spectrum heat with a higher published maximum, a 120V circuit, and $3,751 back in your pocket — accepting no red light and no app. Choose the Eclipse 4 if integrated red light, the native app, four-person capacity, and named-lab brand documentation are worth the higher price and a 240V/30A circuit. Choose the Matterhorn if published irradiance figures, the compact footprint, and the feature bundle at $10,750 fit your priorities — and get its warranty, Wellness Club, and return terms in writing first.

Frequently Asked Questions

Is the Peak Saunas Matterhorn a good sauna?

Peak's pages describe a three-person cedar sauna with full-spectrum heat to a stated 150°F, two integrated red-light panels, phone control, and a $10,750 price with free delivery — every performance figure manufacturer-stated. The documented problems are consistency and verification: Peak's current pages publish conflicting warranty terms and conflicting Wellness Club pricing, its heater count differs between its own pages, its remote control spans two apps, and no independent exact-model thermal, EMF, air-quality, or optical report was identified. A verified owner's detailed review — positive overall — also flagged red-light panel clearance and timer friction and a floor heater that runs uncomfortably hot at higher settings.

What is the best alternative to the Peak Matterhorn?

It depends on why you're considering it. For three-person capacity and infrared heat at lower cost, the Sun Home Equinox 3 ( $7,699) publishes a higher 165°F maximum on a 120V/20A circuit — $3,751 cheaper, without integrated red light or an app. For integrated red light with more capacity and named-lab brand documentation, the Sun Home Eclipse 4 ( $13,599) pairs a four-person cabin with dual red-light towers and the native Sun Home app. Within the competitor's own lineup, the hemlock Denali delivers identical Matterhorn hardware for $1,000 less.

How much more does the Matterhorn cost than the Sun Home Equinox 3?

$3,751 more at prices verified August 6, 2026 — the competitor Matterhorn's $10,750 versus the cheaper $7,699. That premium buys integrated red light with published irradiance data, app-based control, cedar construction, an ionizer, and a foot heater; it does not buy a higher published maximum temperature (150°F versus 165°F) or a lighter electrical requirement (dedicated 240V versus 120V/20A).

Does the Matterhorn require an electrician?

Plan on it. Peak's specification lists 240V/20A at 2,850W on a dedicated circuit with a NEMA 6-20P plug, and Peak itself recommends professional installation. The Equinox 3 runs on a 120V/20A dedicated circuit (no electrician if a 20A receptacle already exists at the location); the Eclipse 4 requires its own dedicated 240V/30A circuit with a NEMA L6-30P receptacle.

Is the Matterhorn's lifetime warranty really lifetime?

Peak's governing warranty table defines "lifetime" on heating elements and cabinetry as 7 years of normal residential use, with controls at 3 years, and chromotherapy, sound, accessories, and app connectivity at 1 year — labor excluded and parts freight customer-paid after 90 days. Be aware that Sun Home's lifetime-branded Eclipse coverage is likewise defined as up to 7 years on cabinetry and heaters; a 7-year definition of core "lifetime" coverage is common in this category. The Matterhorn-specific issue is that other current Peak pages present every component as covered for life and publish different component terms, so get the exact written schedule before purchase — from any brand.

Is Peak Saunas BBB accredited?

Yes. Peak Wellness USA currently holds BBB accreditation with an A+ rating and has been accredited since March 28, 2024; older comparisons stating otherwise are out of date. BBB status reflects business practices and complaint handling; it is not evidence of product performance for either brand.

Is the Matterhorn really a three-person sauna?

It is listed for three, and its 57-inch interior width matches the category norm — the Equinox 3 is 56.8 inches. A verified Matterhorn owner described it as spacious for two and snug for three, which is the honest way to read most three-person cabins from most manufacturers. Treat three as occasional maximum capacity and two adults as the comfortable routine number; buyers who need true room for three or more should compare four-person cabins like the Eclipse 4.

Does the Matterhorn direct its full-spectrum heat at your body?

Not from the front, based on Peak's own product photography. The near- and mid-infrared bands come from halogen/quartz emitters, which the photography shows mounted on the side wall behind wooden grilles; Peak publishes no panel-position map, and its pages conflict on the total panel count. The hardware facing seated occupants is the pair of LED red-light panels — light-therapy devices, not infrared heat emitters. The far-infrared carbon panels still warm the cabin generally; the gap concerns front-directed near- and mid-infrared exposure specifically, and buyers who want it should ask Peak for emitter positions in writing. The Eclipse 4 publishes its full-spectrum heaters on the back wall, directed at the seated body.

Which has better red light therapy — the Matterhorn or the Eclipse 4?

Neither claim can be settled with current documentation, so compare what each publishes. The Matterhorn's page lists more optical figures — eight wavelengths, a beam angle, and irradiance at three distances across two front-wall panels — all manufacturer-stated. The Eclipse 4 publishes two wavelengths (650 nm and 850 nm), a 360-LED count, and a 900W rating per panel across two full-height towers, with no irradiance figure. Both brands describe their LEDs as medical-grade — manufacturer terminology in both cases — and neither publishes an independent optical report, a uniformity map, or exact-model verification. If a published irradiance number for the integrated panels matters most to you, the Matterhorn lists one and the Eclipse 4 does not — Sun Home's published irradiance sits on its Luminar red light panel instead[12] — and every optical figure from either brand is manufacturer-stated and unverified; if you weight named-lab brand safety documentation, capacity, and a single governing warranty document, the Eclipse 4 leads.
