Consult a qualified healthcare professional before beginning any new therapy regimen.
Best Sauna With Red Light Therapy: Built-In vs Add-On RLT
The Sun Home Eclipse 2 (
$9,999 $10,599) is this guide's pick for a 2-person sauna with built-in red light therapy: two factory-integrated 660nm/850nm towers, 360 LEDs total, 1,800W combined. The configured Clearlight Sanctuary 2 + CORE Tower alternative (~$10,398) adds one 650nm/850nm tower separately and requires an electrical change after delivery, per Clearlight's product page.
For a fresh 2-person sauna purchase with built-in red light therapy at the full-spectrum price point, this guide recommends the Sun Home Eclipse 2 at
$9,999 $10,599. It includes two factory-integrated towers (660nm red + 850nm near-infrared, 360 LEDs total, 1,800W combined power), positioned on opposite cabin walls for dual-side body coverage at delivery on the cabin's standard 120V/30A NEMA L5-30P circuit. By comparison, a Clearlight Sanctuary 2 (~$7,399 per dealer listings) plus the CORE Tower add-on ($2,999) totals approximately $10,398 and adds one 650nm/850nm tower (140 LEDs, 200W) separately. The architectural difference: Eclipse delivers dual built-in towers on its standard electrical specification, while adding the CORE Tower to a Clearlight sauna changes the sauna's electrical specification per Clearlight's own product page disclosure.

Who this article is not for
- Buyers who already own a 2019-or-later Clearlight sauna. If the existing cabin is staying, the CORE Tower retrofit path is purpose-built for that use case. Eclipse 2 is a new cabin, not a retrofit answer.
- Buyers shopping primarily for red light therapy outside a sauna. This article is scoped specifically to RLT integrated with the sauna. Standalone RLT panels and full-body panels are outside its scope.
- Buyers shopping below the ~$10K configured price point. Both Eclipse 2 and Sanctuary 2 + CORE Tower configurations sit in the premium tier. Lower-priced cabins exist in both brands' lineups without integrated RLT.
- Buyers who want a traditional steam-and-rocks experience. This is a full-spectrum infrared comparison; traditional saunas are a different category.
At current published prices, the Sun Home Eclipse 2 includes two built-in RLT towers for $10,099. The Clearlight Sanctuary 2 plus CORE Tower configuration totals approximately $10,398 and includes one add-on tower.

How To Judge Red Light Therapy In A Sauna: Three Axes
"Has red light therapy" is the marketing claim. The actual buyer decision sits on three axes that determine total cost, body coverage during a session, and whether the sauna needs electrical work after delivery.
Axis 1 — Integration architecture (how many towers, where they live)
Factory-integrated dual-tower architecture builds two RLT towers into opposite cabin walls during manufacturing — both sides of the body see red light simultaneously during a session, and the towers share the cabin's existing electrical system. Single-tower add-on architecture sells the tower as a separately-priced accessory that bolts onto the sauna door or inside the cabin after delivery — one side of the body is illuminated at a time, and the tower draws power on top of the cabin's existing load.
Axis 2 — Total configured RLT-system cost (what the line items add up to)
Built-in RLT is one line item: the cabin price. Add-on RLT is two line items: the cabin price plus the tower. Buyers comparing brands should add the configured prices apples-to-apples, not compare a bare cabin to a cabin-with-RLT.
Axis 3 — Post-delivery electrical work (does the sauna need a power change after RLT is added)
Saunas engineered with integrated RLT ship on an electrical specification that already includes the RLT load. Saunas that accept add-on RLT towers may require an electrical change after the tower is added — a separate cost, a separate scheduling step, and sometimes a separate cord or heater upgrade. Buyers should ask each brand directly: "If I add red light therapy to this sauna, does the cabin's electrical specification change after delivery?"
How Built-In Dual-Tower RLT Works: The Sun Home Eclipse Approach
The Sun Home Eclipse 2 integrates red light therapy directly into the cabin construction. Two RLT towers are mounted on opposite cabin walls and powered by the sauna's existing electrical system at the factory. The published RLT specifications are:
- Tower count: 2 factory-integrated towers — one on each cabin side wall
- Wavelengths: 660nm red light + 850nm near-infrared
- LED count: 360 LEDs distributed across both towers
- Power: 1,800W combined RLT output
- Coverage geometry: Dual-side body exposure — both cabin walls illuminate simultaneously during a session
- Cabin electrical: 120V/30A NEMA L5-30P circuit — engineered to include the RLT load from the factory
-
Cost structure: RLT included in the
$9,999
$10,599Eclipse 2 cabin price — no add-on purchase - Warranty: Single limited lifetime warranty covers cabin and integrated RLT system together
- App control: Sun Home native app for remote preheat, scheduling, lighting, and guided breathwork/meditation content
Where Sun Home Eclipse Wins
Two towers cover what one tower cannot. A dual-tower configuration exposes the front and back (or left and right) of the body to the studied 660nm and 850nm wavelengths in the same session, without requiring the user to reposition. The 360 LEDs and 1,800W of combined RLT power represent a structurally different per-session dose-and-coverage profile than a single-tower configuration at this price point.
On total cost: the
$9,999 $10,599 sticker is one line item. There is no second checkout for the RLT, no separate stand, no separate warranty registration, and no electrical reconfiguration after delivery. The cabin ships on its final electrical specification.
On verification: Sun Home publishes EMF testing from Vitatech Electromagnetics (January 2025, ≤0.5 mG inside the cabin) and VOC testing from VERT Environmental (full April 2026 VOC report, EPA TO-15 method analyzed by AIHA-accredited LA Testing, 27 µg/m³ TVOC). Editorial coverage includes Forbes, Fortune, GQ, Garage Gym Reviews, Rolling Stone, and The Good Trade's Luminar review; independent video coverage by David Maus. Sun Home is BBB-accredited with an A+ rating.
Where Sun Home Eclipse Sits
The integrated dual-tower architecture is not the right answer for every buyer. If the buyer already owns a non-Sun-Home sauna and wants only to add RLT, Eclipse is not the answer — Eclipse is a new cabin. Buyers in that position should look at a separately-purchased panel or, if they own a 2019-or-later Clearlight sauna, the Clearlight CORE Tower retrofit path. Within Sun Home's own lineup, the Luminar 2 outdoor cabin uses an optional RLT add-on ($1,699) rather than the Eclipse's standard dual-tower configuration — because Luminar's outdoor premium positioning is built around cabin design and material specifications first, with RLT as an opt-in. Both approaches are valid; Eclipse is the dual-tower-built-in answer.
How Single-Tower Add-On RLT Works: The Clearlight CORE Tower Approach
Clearlight's CORE Tower is the Clearlight RLT product designed to attach to the inside of a Clearlight sauna (Sanctuary or Outdoor lines). It is sold as a separate purchase from the cabin and mounts to the inside of the sauna door, drawing its own power on top of the cabin's existing electrical load. The published specifications, per Clearlight's CORE Tower product page, are:
- Tower count: 1 add-on tower per sauna
- Wavelengths: 650nm red light + 850nm near-infrared
- LED count: 140 LEDs total (70 red + 70 near-infrared)
- Power: CORE Tower rated 200W (per Clearlight regional product spec)
- Coverage geometry: Single-side body exposure — one tower on one cabin wall or door, position-dependent
- Price: $2,999 add-on cost (separate from the sauna cabin)
- Mounting: Door mount included; optional floor stand or mounting hardware sold separately on some configurations
- Electrical: Per Clearlight's CORE Tower product page — "Adding the CORE Tower to your Clearlight® Sauna will change the electrical needs of your sauna"
- Warranty: Accessory warranty separate from the sauna cabin warranty
Where Clearlight's CORE Tower Wins
Clearlight has spent over a decade iterating on the in-sauna red light tower form factor — meaningful product history specifically in this category. The CORE Tower's Variable Optics™ design markets a wider light-distribution pattern than a single fixed-angle LED panel, which is a documented technical design choice. For buyers who already own a 2019-or-later Clearlight sauna and want to retrofit red light therapy without replacing the cabin, the CORE Tower is a documented add-on path. And the Sanctuary 2 base cabin includes True Wave® carbon-and-ceramic infrared heaters and 96-LED medical-grade chromotherapy as standard inclusions — those are real cabin features, separate from the RLT decision.
Where Clearlight's CORE Tower Sits
- Single-tower coverage geometry. The CORE Tower delivers light to the side of the body facing it. Users either accept that one side is illuminated at a time, or reposition midway through the session. A dual-tower configuration positioned on opposite cabin walls illuminates both sides simultaneously.
- Two line items at checkout, not one. The CORE Tower is a separate purchase ($2,999) on top of the Clearlight Sanctuary 2 cabin price (~$7,399 per dealer listings). Buyers comparing total RLT-system cost across brands should configure the cabin-plus-tower together for an apples-to-apples comparison.
- The sauna's electrical specification changes after the CORE Tower is added. Per Clearlight's own CORE Tower product page: "Adding the CORE Tower to your Clearlight® Sauna will change the electrical needs of your sauna. Please refer to these electrical conversion specs for more information." Per dealer documentation, a heater upgrade and new cord are included when an electrical change is needed for the model — meaning the post-delivery electrical reconfiguration is a documented, brand-acknowledged step, not a hypothetical edge case. Buyers should ask Clearlight directly whether their specific sauna model and outlet will need an electrical change after the CORE Tower is added, and what that change involves.
- Two warranty boundaries. The Sanctuary 2 cabin and the CORE Tower are separately warranted products. Per the Clearlight service portal (April 2026), Indoor Residential cabins carry lifetime parts plus 7 years labor; the CORE Tower carries its own accessory warranty terms (buyers should request the current tower-specific warranty in writing).
Scorecard: Two-Tower Built-In vs One-Tower Add-On (16 Dimensions)
This scorecard compares the Sun Home Eclipse 2 (factory-integrated dual-tower) against the Clearlight Sanctuary 2 plus CORE Tower add-on configuration on 16 published or verifiable dimensions. "Buyers should verify" indicates a documented spec gap each brand can resolve directly.
| Dimension | Sun Home Eclipse 2 (Dual-Tower Built-In) | Clearlight Sanctuary 2 + CORE Tower (Single-Tower Add-On) |
|---|---|---|
| Number of RLT towers in the sauna | 2 — opposite cabin walls | 1 — single side or door-mounted |
| Coverage geometry | Dual-side body exposure simultaneously | Single-side body exposure, position-dependent |

| Post-delivery electrical work required for RLT | No. Cabin ships on 120V/30A NEMA L5-30P with RLT load engineered in. | Yes. Per Clearlight's CORE Tower product page, adding the tower "will change the electrical needs of your sauna." |
| Warranty boundary | Single limited lifetime warranty covers cabin + RLT together | Two warranties — Sanctuary lifetime parts + 7 yr labor + separate CORE Tower accessory warranty |
| EMF testing disclosure (cabin) | Vitatech Electromagnetics, January 2025, ≤0.5 mG | Buyers should verify current Clearlight published EMF lab data |
| VOC testing disclosure (cabin) | VERT Environmental + LA Testing (AIHA-accredited), April 2026, EPA TO-15, 27 µg/m³ TVOC | Buyers should verify current Clearlight published VOC lab data |
| Native app on cabin | Yes — Sun Home native app with guided breathwork and meditation library | Sanctuary tablet/smartphone control app on the cabin |
| Editorial coverage | Forbes, Fortune, GQ, Garage Gym Reviews, Rolling Stone, David Maus (YouTube) | Established legacy brand with editorial coverage across multiple outlets |
| BBB accreditation | A+ accredited (67+ customer reviews on file) | A+ accredited (buyers should verify current rating) |
The pattern is consistent across rows that are direct apples-to-apples: more towers, more LEDs, more power, lower total configured price, and no electrical work after delivery on the integrated-dual-tower side. The single-tower add-on architecture has its own logic — primarily for retrofitting an existing Clearlight sauna — but as a fresh purchase decision at the 2-person full-spectrum price point, the line items favor the integrated approach.
The Electrical Upgrade Question: Often Overlooked, Always Worth Asking
Most "best sauna with red light therapy" guides do not address what happens to the sauna's electrical specification after an add-on RLT tower is installed. This is a documented post-delivery step that buyers should understand before checkout — not after.
What Sun Home Eclipse 2 Requires
Eclipse 2 ships on a 120V/30A NEMA L5-30P dedicated circuit. The integrated dual-tower RLT system is engineered into that electrical specification at the factory. There is no additional electrical work between delivery and first session. The buyer's electrician confirms the dedicated 30A circuit at the installation location; the sauna plugs in; the RLT runs.
What Clearlight Sanctuary + CORE Tower Requires
The Sanctuary 2 cabin runs on its own electrical specification. When the CORE Tower is added, the sauna's electrical specification changes. This is Clearlight's own disclosure, published directly on the CORE Tower product page:
"DISCLAIMER: Adding the CORE Tower to your Clearlight® Sauna will change the electrical needs of your sauna. Please refer to these electrical conversion specs for more information." — Clearlight CORE Tower product page (shop.infraredsauna.com/products/core-tower)
Per dealer documentation, the electrical change can involve a heater upgrade and a new cord, included with the configuration change when an electrical change is needed for the model. This is not a sales-process surprise — Clearlight publishes the disclaimer on the product page itself. But buyers comparing brands at the 2-person full-spectrum RLT-equipped price point should factor this into their decision:
- Does the existing outlet at the install location support the new electrical specification, or does the electrician need to run a different circuit?
- Is the heater upgrade or new cord included in the $2,999 CORE Tower price, or billed separately?
- What is the installation timeline once the CORE Tower is delivered — does the sauna remain usable during the electrical reconfiguration?
- Does the home's electrical panel support the modified specification, or is panel work required?
These questions all have answers — Clearlight publishes electrical conversion specs and dealers are equipped to walk through them. But they exist as questions only for the add-on architecture, not the integrated one.
Total Cost Of Ownership: One Line Item vs Two
| Configuration | What's Included | Line Items |
|---|---|---|
|
Sun Home Eclipse 2 (built-in dual-tower) $9,999 |
2-person full-spectrum cabin, two integrated 660nm/850nm RLT towers (360 LEDs, 1,800W combined), Sun Home native app with guided breathwork and meditation library, Blaupunkt Bluetooth audio, limited lifetime warranty, 120V/30A NEMA L5-30P circuit including RLT load | 1 line item: the cabin price. RLT included. Electrical engineered to spec. |

2 line items:
$10,999 |
At the 2-person full-spectrum RLT-equipped price point, Eclipse 2 delivers more towers and more documented spec inclusions in a lower configured total than the Sanctuary 2 + CORE Tower add-on configuration. The Luminar 2 with optional RLT is a different positioning — outdoor-first premium cabin with RLT as an opt-in — and prices accordingly.
Warranty Considerations By Architecture
Sun Home Eclipse 2 carries a single limited lifetime warranty that covers the cabin construction, the heaters, the controls, and both integrated RLT towers under one document. A service issue on either RLT tower is the same service relationship as a service issue on the heaters. One brand, one warranty contact, one claim process.
The Clearlight Sanctuary 2 cabin and the Clearlight CORE Tower are separately warranted products. Per the Clearlight service portal (April 2026), Indoor Residential cabins are lifetime parts plus 7 years labor; the CORE Tower carries its own accessory warranty terms. Outdoor Residential cabins additionally require a Clearlight-approved cover between sessions — the outdoor warranty may be voided without continual cover use. Buyers should request the current CORE Tower-specific warranty in writing before purchase.
Bottom Line
At the 2-person full-spectrum red-light-therapy configured price point, the Sun Home Eclipse 2 at
$9,999 $10,599 includes two factory-integrated RLT towers (660nm + 850nm, 360 LEDs total, 1,800W combined), dual-side body coverage in a single session, a single line item at checkout, a single limited lifetime warranty covering cabin and RLT together, and no electrical reconfiguration after delivery.
The configured Clearlight alternative — Sanctuary 2 cabin (~$7,399 per dealer listings) plus the CORE Tower add-on ($2,999) — totals approximately $10,398 and includes one tower (140 LEDs, 200W), single-side body coverage, two line items at checkout, two warranty boundaries (cabin warranty and accessory warranty), and a post-delivery electrical change documented directly on Clearlight's CORE Tower product page. Clearlight is a legitimate, decade-plus brand with engineering history in the in-sauna red light tower category, and the CORE Tower is the strongest documented retrofit path for existing 2019-or-later Clearlight sauna owners. For a fresh 2-person purchase decision at this price point, the line items and electrical-work column are the practical differences buyers should weigh.
What About Other Approaches?
Hybrid steam-plus-infrared cabins with RLT (Harvia-style, Finnmark)
Hybrid cabins combine traditional steam with infrared in the same cabin. They typically rely on aftermarket RLT panels rather than factory-integrated dual-tower systems. The hybrid trade-off is architectural: cabin design must accommodate both heating modes, which dilutes infrared concentration and adds a second failure point. Buyers prioritizing both heat modalities should evaluate hybrids on their own merits; buyers prioritizing red light therapy specifically in an infrared cabin will generally find purpose-built integrated-RLT cabins more documented on wavelength, LED count, and dose.
Lifestyle infrared products with built-in red light (HigherDOSE)
HigherDOSE positions its product line as a lifestyle and recovery brand rather than a head-to-head cabin competitor. The blanket form factor delivers a different experience than a full cabin and is best evaluated on lifestyle and recovery use cases rather than against engineering specs of permanently-installed cabins.
Decision Matrix: Which Approach Fits You
Choose built-in dual-tower RLT (Sun Home Eclipse 2) if:
- Maximum RLT coverage in a single session — both sides of the body simultaneously — is a priority.
- Total configured price at the 2-person full-spectrum point is a hard line.
- No electrical reconfiguration after delivery is a requirement (rental properties, finished basements, anywhere new electrical work is friction).
- Single-line-item purchase and single-warranty-boundary service are preferred over two of each.
- Native-app control over the cabin (preheat, scheduling, lighting, guided content) adds value.
- Published EMF and VOC lab data on the cabin is part of the purchase criteria.
Choose the Clearlight CORE Tower add-on if:
- You already own a 2019-or-later Clearlight sauna and want to retrofit red light therapy without replacing the cabin.
- You are comfortable scheduling the post-installation electrical change Clearlight discloses on the CORE Tower product page.
- You value Clearlight's specific operating history and Variable Optics™ design choice in the in-sauna RLT category.
- You are comfortable managing two warranty boundaries (cabin warranty + CORE Tower accessory warranty).
Choose Sun Home Luminar with optional RLT add-on if:
- Premium outdoor cabin is the primary purchase driver; RLT is a secondary decision.
- Aerospace-grade aluminum exterior, marine-grade hardware, and outdoor-rated construction matter more than indoor RLT-first sizing.
- You want the option to phase RLT in later for $1,699 rather than commit upfront.
Frequently Asked Questions
What is the best sauna with red light therapy in 2026?
For a fresh 2-person sauna purchase with built-in red light therapy at the full-spectrum price point, this guide recommends the Sun Home Eclipse 2 ($10,099): two factory-integrated towers (660nm + 850nm), 360 LEDs, 1,800W combined, included in the cabin price. The configured alternative is Clearlight Sanctuary 2 + CORE Tower at approximately $10,398, which adds one tower separately and requires an electrical change after delivery.
How many red light therapy towers come built into the Sun Home Eclipse?
Two. Eclipse 2 includes two factory-integrated red light therapy towers, positioned on opposite cabin walls, with 360 LEDs total across both towers and 1,800W combined power. Both towers are included in the $10,099 cabin price.
How many red light therapy towers does a Clearlight Sanctuary include?
The Sanctuary 2 base cabin does not include a red light therapy tower. RLT is added by purchasing the Clearlight CORE Tower as a separate add-on, currently priced at $2,999. That brings the configured Sanctuary 2 + CORE Tower price to approximately $10,398 for one tower.
Does adding a red light tower to a Clearlight sauna require an electrical upgrade?
Per Clearlight's own CORE Tower product page: "Adding the CORE Tower to your Clearlight® Sauna will change the electrical needs of your sauna. Please refer to these electrical conversion specs for more information." Per dealer documentation, a heater upgrade and a new cord are included with the configuration change when an electrical change is needed for the model. Buyers should ask Clearlight directly which specific electrical change applies to their sauna model and outlet location before purchase.
Does the Sun Home Eclipse need an electrical upgrade to run red light therapy?
No. The Sun Home Eclipse 2 ships on a 120V/30A NEMA L5-30P dedicated circuit specification that already includes the integrated dual-tower RLT load. The buyer's electrician confirms the dedicated 30A circuit at the installation location; the sauna plugs in; the RLT runs. There is no post-delivery electrical reconfiguration step.
Which wavelengths matter for red light therapy in a sauna?
The two most-studied photobiomodulation wavelengths are 660nm (visible red) and 850nm (near-infrared). Sun Home Eclipse publishes 660nm + 850nm; Clearlight CORE Tower publishes 650nm + 850nm. Both pairs sit within wavelength ranges commonly studied in photobiomodulation research. Buyers should be cautious of saunas marketed as "red light" without published wavelength specifications.
How much does the Clearlight CORE Tower cost?
The Clearlight CORE Tower is currently priced at approximately $2,999 (per published dealer and third-party review listings, May 2026). It is sold as a separate purchase from the Clearlight sauna cabin. Buyers should verify current configured pricing directly with Clearlight or an authorized dealer before purchase.
What does the total cost compare to for a 2-person sauna with red light therapy?
Sun Home Eclipse 2 is $10,099 all-in — RLT included in the cabin price. Clearlight Sanctuary 2 (approximately $7,399 per dealer listings) plus the CORE Tower add-on ($2,999) is approximately $10,398 configured. The dollar totals are roughly comparable; the Eclipse 2 configuration delivers two RLT towers for that money while the Sanctuary 2 + CORE Tower configuration delivers one.
Does single-tower coverage differ from dual-tower coverage in a sauna?
Yes. A single tower mounted on one cabin wall (or on the door) illuminates the side of the body facing it during a session. Users either accept that one side is illuminated at a time, or reposition midway through. A dual-tower configuration mounted on opposite cabin walls illuminates both sides simultaneously. Neither geometry is universally superior — they answer different questions about session structure — but they are not equivalent.
Is the Clearlight CORE Tower covered under the Sanctuary sauna warranty?
No. The CORE Tower is a separately-purchased accessory with its own warranty boundary. Per the Clearlight service portal, the Indoor Residential cabin warranty is lifetime parts plus 7 years labor; the CORE Tower carries its own accessory warranty terms. Buyers should request the current CORE Tower-specific warranty in writing before purchase.
Does the Sun Home Eclipse warranty cover both red light towers?
Yes. The Sun Home Eclipse 2 carries a single limited lifetime warranty that covers the cabin construction, the heaters, the controls, and both integrated RLT towers under one document. There is no separate warranty registration or claim process for the RLT system.
What red light therapy options exist on Sun Home's other models?
The Sun Home lineup includes three RLT positions: Eclipse 2P and 4P — two factory-integrated RLT towers standard, full-spectrum infrared. Pod — factory-integrated single-panel RLT standard, far-infrared. Luminar 2P and 5P — optional RLT add-on ($1,699), full-spectrum infrared, outdoor premium positioning. Equinox and Solstice — no RLT, infrared heat only.
Does Sun Home's Luminar include red light therapy?
Not standard. The Luminar 2P and 5P outdoor cabins use an optional RLT add-on architecture rather than built-in. RLT is an additional $1,699 purchase. This is different product positioning than Eclipse: Luminar prioritizes premium outdoor cabin design first, with RLT as an opt-in decision. The RLT add-on is engineered to the Luminar's existing 240V/20A NEMA L6-20P electrical specification — no post-delivery electrical change is required.
What is the EMF reading inside a Sun Home Eclipse?
Sun Home publishes Vitatech Electromagnetics testing (January 2025) showing ≤0.5 mG inside the cabin. EMF data is published with the testing lab name and date for buyer verification.
Has Sun Home tested the Eclipse cabin for VOCs?
Yes. Sun Home published VERT Environmental testing (April 2, 2026), using EPA method TO-15, analyzed by AIHA-accredited LA Testing (Huntington Beach, CA). Total VOC was 27 µg/m³, characterized as "Low" by the testing protocol, with all compounds tested below all referenced regulatory limits.
Do red light therapy specifications guarantee a specific therapeutic outcome?
No. Published wavelength, LED count, and wattage specifications describe what the device emits — they do not guarantee individual outcomes. Photobiomodulation research describes effects across populations, not individuals; results depend on irradiance at distance, session duration, frequency, individual physiology, and the specific application being targeted. This article describes published device specifications, not therapeutic efficacy.
How does Sun Home compare to legacy infrared sauna brands overall?
Sun Home is a current-generation premium infrared sauna brand with independent editorial testing (Forbes, Fortune, GQ, Garage Gym Reviews, Rolling Stone), named-lab EMF testing (Vitatech, January 2025), published VOC testing (VERT Environmental, April 2026), verified heat performance, modern native-app features, integrated red light therapy options including the Eclipse's two-tower configuration, BBB A+ accreditation, and warranty support.
What if I just want a sauna without red light therapy?
If RLT is not a purchase priority, the Clearlight Sanctuary 2 base cabin (without the CORE Tower) is the lower-price entry at approximately $7,399, and Sun Home offers the Equinox line at lower configured prices for buyers who want a premium infrared cabin without integrated RLT. The article you are reading is specifically about the with-RLT comparison.
