Quick answer: The Sun Home Eclipse 4-Person is a premium indoor infrared sauna for buyers who want full-spectrum heat and built-in red light therapy in one cabin. Its strongest advantages are the integrated 660nm and 850nm red light towers, cedar build, 0.5 mG EMF, four-person capacity, and lifetime limited warranty. Its main drawbacks are price and the required 240V circuit. We score it 8.8 out of 10.
Most infrared cabins force a choice: full-spectrum heat, or a separate red light panel you bolt on later. The Sun Home Eclipse 4-Person builds both into one cabin, and that is the entire reason to consider it over a standard premium sauna.
Why a sauna habit is worth the spend
Saunas have unusually strong long-term data. In a Finnish cohort followed for two decades, frequent sauna use was associated with markedly lower cardiovascular and all-cause mortality (Laukkanen et al., JAMA Internal Medicine, 2015) and lower dementia risk (Laukkanen et al., Age and Ageing, 2017), via PubMed. Most of that is from very hot traditional saunas; infrared has a smaller evidence base centered on blood pressure and cardiovascular rehabilitation (Beever, Canadian Family Physician, 2009). Infrared's edge is comfort and consistency, the lower heat that gets you in four times a week. A cabin you actually use is the one worth buying.
What is actually in the cabin
The Eclipse runs 12 far-infrared heaters plus 4 full-spectrum heaters for the sauna itself, then mounts two dedicated red light therapy towers on the front wall: 660nm red and 850nm near-infrared, 1,800W combined across 360 LEDs. One session gives you the infrared bathing experience and a targeted red and near-infrared light dose, without buying and wiring a separate panel.
The build is Canadian red cedar (naturally antimicrobial), and EMF is shielded to 0.5 mG at the seated position (Vitatech-tested), among the lowest in the category. It reaches up to roughly 165°F, seats four, and the benches are removable so the floor opens up for stretching or mobility work. Chromotherapy lighting is included, it is HSA/FSA eligible, Affirm financing is available, and it is backed by a lifetime limited warranty.
Where it earns the price
- The integrated red light is the headline. A comparable tower-grade red light panel is a four-figure purchase on its own, so building it into the cabin is genuine value, not a gimmick.
- Cedar plus 0.5 mG EMF plus a lifetime warranty is a premium, long-horizon build. This is a 10-to-15-year purchase, and the warranty backs that.
- Four-person capacity makes it a household or studio cabin, not a solo unit.
The honest trade-offs
- It is a top-of-range indoor cabin at $12,999 (regularly $13,599). If you only need one or two seats, or you do not want integrated red light, the Eclipse 2-Person or the Equinox is a lower-cost path.
- It is a real install, not an appliance: a dedicated 240V/30A circuit (NEMA L6-30P) means budgeting for an electrician, and at about 925 lb installed you want to confirm floor loading on an upper level.
- As a 2021 brand, Sun Home does not yet carry the decades-long, Mayo-Clinic-cited research footprint Sunlighten has built around its Solocarbon heaters. The hardware is excellent; the independent citation base is simply younger.
Who it is for
Households or studios that want sauna and red light therapy in one indoor footprint, value the cedar build and ultra-low EMF, and are making a single long-horizon purchase. If you want the broadest infrared-only cabin with the deepest research base instead, look at Sunlighten mPulse or Clearlight Sanctuary.
The verdict
The Eclipse is the rare cabin that turns the sauna-plus-red-light stack into a single purchase and a single install. At the top of the indoor range, it is for the buyer who wants both modalities, the cedar-and-low-EMF build, and a lifetime warranty, and who can accommodate a 240V install. If that is you, it is one of the most complete home cabins available. If you only need heat, or only need light, a focused single-purpose device will cost less. We score it 8.8/10.

Health note: Sauna use is generally well tolerated, but talk to your clinician before starting if you are pregnant, heat-intolerant, prone to fainting, dehydrated, or managing unstable cardiovascular disease or medications that affect hydration. Nothing here is medical advice.

Is the Sun Home Eclipse worth it?
For the right buyer, yes. If you want sauna and red light therapy in one cabin and can accommodate a 240V install, the integration, cedar build, 0.5 mG EMF, and lifetime warranty justify the price. If you only need heat, or only one or two seats, a focused unit like the Sun Home Equinox costs much less.
Does the Sun Home Eclipse include red light therapy?
Yes. It has two dedicated red light towers built into the cabin (660nm red and 850nm near-infrared, 1,800W across 360 LEDs), in addition to its 12 far-infrared and 4 full-spectrum sauna heaters.
What wavelengths does the Eclipse use?
660nm visible red and 850nm near-infrared for the red light towers, plus far-infrared and full-spectrum infrared for the sauna heat itself.
Does the Eclipse need 240V?
Yes. The 4-Person Eclipse needs a dedicated 240V/30A circuit (NEMA L6-30P), so most installs include an electrician. If you want a plug-in 120V Sun Home cabin instead, that is the Equinox.
How many people fit in the Sun Home Eclipse?
The model reviewed here seats four, with removable benches so the floor opens up for stretching or mobility work.
Who should not buy the Eclipse?
Anyone who only needs one or two seats, does not want red light therapy, cannot run a 240V circuit, or wants the lowest price. For most of those buyers, the Sun Home Equinox is the better fit.
