Sun Home Eclipse vs Clearlight Sanctuary (2026): Built-In Red Light or Pure Infrared?
One builds red light therapy into the cabin; the other is the established pure-infrared pick with the deepest service network. Which premium sauna fits comes down to one question.
Partner content: Sun Home is a Lifespan Vault partner. This comparison was produced as part of that partnership. The specs, scoring, and verdict below are independent and verified against each manufacturer.
Quick answer: Choose the Sun Home Eclipse if you want infrared sauna plus built-in red light therapy in one four-person cabin. Choose the Clearlight Sanctuary if you want a lower entry price, more size options, and the longer pure-infrared service pedigree. The Eclipse is the more complete cabin; Clearlight is the more flexible pure-infrared buy.
These two get cross-shopped because they sit at the premium end of full-spectrum infrared, but they answer different questions. The Sun Home Eclipse builds dedicated red light therapy into the sauna. The Clearlight Sanctuary is a pure infrared cabin from the brand with the deepest service network in the category. The decision comes down to one question: do you want red light therapy in the cabin, or the broadest, longest-supported pure-infrared build?
The core trade
The Eclipse 4-Person pairs full-spectrum infrared heaters with two dedicated red light towers (660nm red and 850nm near-infrared, 1,800W across 360 LEDs), so one session covers heat and a targeted light dose. The Clearlight Sanctuary is full-spectrum infrared only: no dedicated red light LED towers, but category-benchmark-low EMF, a lifetime warranty on the whole cabin, and Jacuzzi-backed service since the 2021 acquisition.
Sun Home Eclipse 4-Person
Indoor, Canadian red cedar, 12 far-infrared and 4 full-spectrum heaters plus the two red light towers. 0.5 mG EMF (Vitatech-tested), up to roughly 165°F, removable benches, chromotherapy, HSA/FSA eligible, lifetime limited warranty. $12,999 (regularly $13,599) for the 4-person. The whole pitch is integration: sauna and red light therapy in one cabin and one install, instead of a cabin plus a separate four-figure light panel.
Clearlight Sanctuary 2
True Wave full-spectrum infrared (near, mid, far), with the category's benchmark-low EMF (typically under 1 mG at the body), a lifetime warranty on cabin and heaters, and Jacuzzi's dealer and service network behind it. Available 1 to 5-person from $5,495 to $9,295, eucalyptus or cedar, chromotherapy included, made in the USA. Founded in 1997, it is the established pure-infrared pick.
Spec comparison
| Spec | Sun Home Eclipse 4-Person | Clearlight Sanctuary 2 |
|---|---|---|
| Heat | 12 far-IR + 4 full-spectrum | True Wave full-spectrum (near/mid/far) |
| Dedicated red light | Yes (660nm + 850nm, 1,800W, 360 LEDs) | No |
| EMF at body | 0.5 mG | under 1 mG |
| Warranty | Lifetime limited | Lifetime cabin + heaters |
| Capacity | 4-person | 1 to 5-person |
| Build | Canadian red cedar | Eucalyptus or cedar |
| Price | $12,999 (4-person) | $5,495 to $9,295 |
Where the Eclipse wins
- Built-in red light therapy. The real differentiator. Clearlight has no dedicated 660/850nm towers, so matching the Eclipse means buying and wiring a separate red light panel, a four-figure add on its own.
- Lower published EMF. The Eclipse posts 0.5 mG versus the Sanctuary's under 1 mG, so on the published figures the Eclipse is the lower-EMF cabin.
- One cabin, one install for both modalities, and four seats.
Where the Clearlight wins
- Lower entry price and more sizes. A 1-person Sanctuary starts at $5,495 and scales to 5-person, so it is the pick if budget or a specific size leads your decision.
- Service pedigree. A 1997 founding date and Jacuzzi's dealer network, versus Sun Home's 2021. If a long parts-and-service track record is your priority, that depth counts.
Decision matrix by buyer type
| If you want... | Buy |
|---|---|
| Built-in red light therapy | Sun Home Eclipse |
| Four seats in one cabin | Sun Home Eclipse |
| The lower published EMF | Sun Home Eclipse (0.5 mG vs under 1 mG) |
| A lower entry price | Clearlight Sanctuary (from $5,495) |
| A one-person option | Clearlight Sanctuary |
| The longest service pedigree | Clearlight Sanctuary (since 1997) |
The verdict
For anyone shopping the premium end, the Eclipse is the one to beat. It does something the Sanctuary cannot, dedicated 660nm and 850nm red light built into the cabin, it posts the lower published EMF figure, and it seats four, all in one install. The Clearlight Sanctuary is still an excellent pure-infrared cabin and the right call if a lower entry price, more sizes, or the longest service pedigree matter most. If you can stretch to it and want the most complete cabin, the Eclipse is the stronger buy.

Is the Sun Home Eclipse better than the Clearlight Sanctuary?
For most premium buyers, the Eclipse is the more complete cabin: it adds built-in red light, posts a lower published EMF figure, and seats four. The Sanctuary is the better buy if a lower entry price, more sizes, or the longest service pedigree matter most.
Which has lower EMF?
On published figures, the Eclipse, at 0.5 mG versus the Sanctuary under 1 mG. Both are ultra-low and well below the level most buyers worry about.
Which has built-in red light therapy?
The Sun Home Eclipse. It includes two dedicated 660nm and 850nm red light towers. The Clearlight Sanctuary has none, so matching the Eclipse means adding a separate panel.
Which is cheaper?
The Clearlight Sanctuary, which starts at $5,495 for a 1-person and scales to 5-person up to $9,295. The Eclipse 4-Person is $12,999.
Which has the better warranty?
Both carry lifetime coverage on the cabin and heaters, so warranty is effectively a wash. The deciding factors are red light, capacity, EMF, price, and service network.
Which is better for a one-person sauna?
The Clearlight Sanctuary, which offers a 1-person configuration. The Eclipse here is a four-person cabin; for one or two seats in the Sun Home line, look at the Equinox.
