The rare 4-person cabin that combines full-spectrum infrared with built-in red light therapy towers, so you are not stacking a separate light panel.

LIFESPANVAULTUse it at Sun Home Saunas →Most infrared cabins make you choose: full-spectrum heat OR a separate red light panel bolted on later. The Sun Home Eclipse 4-Person builds both into one unit. It runs 12 far-infrared heaters plus 4 full-spectrum heaters for the sauna itself, then adds two dedicated red light therapy towers on the front wall delivering 650nm red and 850nm near-infrared (1,800W combined across 360 LEDs). That is the actual reason to look at the Eclipse over a standard premium cabin.
The build is Canadian Hemlock, with patented EMF and ELF shielding measured at 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 bodyweight work. Chromotherapy lighting and a lifetime limited warranty are included, it is HSA/FSA eligible (Sun Home cites an average 30% saving), and Affirm financing is available.
Where it gives ground: this is a premium, permanent install. At $12,999 (regularly $13,599) it sits at the top of the indoor range. It needs a dedicated 240V/30A circuit (NEMA L6-30P), so budget for an electrician, and at 925 lb installed you want to confirm floor loading on upper levels. And 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 buyer this is built for: someone who wants sauna and red light therapy in one indoor footprint for the whole household, values the Canadian Hemlock build and ultra-low EMF, and is making a single long-horizon purchase. The buyer who should skip: anyone who only needs 1-2 seats (the Eclipse 2-person or Equinox is less), wants outdoor placement (the Luminar), or specifically wants the deepest published research base (Sunlighten).

Sun Home Saunas Eclipse 4-Person - buyer FAQ
What makes the Sun Home Eclipse different from a standard infrared sauna?
It integrates red light therapy into the sauna itself. Alongside 12 far-infrared and 4 full-spectrum heaters, the Eclipse mounts two dedicated red light towers (650nm red and 850nm near-infrared, 1,800W across 360 LEDs) on the front wall. Most cabins make you add a separate red light panel later; the Eclipse builds it in.
Is the Eclipse 4-Person worth $12,999?
It is a top-of-range indoor cabin. The value case rests on three things: the built-in red light towers (which would otherwise be a $1,000-plus separate panel), Canadian Hemlock with 0.5 mG EMF shielding, and a lifetime limited warranty. If you only need 1-2 seats or do not want integrated red light, the Eclipse 2-person or the Equinox is a lower-cost path. HSA/FSA eligibility and Affirm financing can offset the sticker.
What does installation require?
The Eclipse 4-Person is indoor-only and needs a dedicated 240V/30A circuit (NEMA L6-30P), so most installs include an electrician quote on top of the sticker. It weighs about 925 lb installed, which is fine on a ground floor or slab but worth a structural check on upper levels. Free shipping is included.
