Sun Home builds full-spectrum infrared saunas that deliver near, mid, and far infrared in a single session, rather than far infrared alone — for relaxation, recovery, skin comfort, and a thorough sweat.
Full-spectrum heaters combine glass-tube near/mid-infrared emitters with flat carbon far-infrared panels, so a single session covers the whole infrared range rather than the far band alone. With independently tested EMF and cabin-air VOC data behind them, the Sun Home Eclipse, Equinox, and Luminar deliver deep, even heat across the cabin.
The Sun Home Luminar was named Best Overall Home Sauna by Fortune (2026) and Best Outdoor Sauna Overall by Garage Gym Reviews (2026). Rolling Stone (2026) named the Equinox 2 its best infrared sauna overall.
Key Takeaways
- Wavelengths: combines near (NIR), mid (MIR), and far (FIR) infrared in every sauna session.
- Sun Home models: Equinox (2P, 3P), Eclipse (2P, 4P), Luminar (2P, 5P).
- Added therapies: Eclipse includes built-in red light therapy; Luminar offers it as an optional add-on.
- Power: circuit size varies — 20A for Equinox (120V) and Luminar 2P (240V); 30A for Eclipse 2P (120V), Eclipse 4P (240V), and Luminar 5P (240V). Connector types are given per model below.
- Wood: eucalyptus (Equinox), Canadian Hemlock (Eclipse), Canadian Red Cedar (Luminar).
What Is a Full-Spectrum Sauna?
A full-spectrum infrared sauna uses heaters that emit all three ranges of the infrared spectrum — near infrared (NIR), mid infrared (MIR), and far infrared (FIR) — in a single session.
Most budget and mid-range infrared saunas emit far infrared only. Full-spectrum saunas deliver a broader range of wavelengths, each targeting different depths and functions in the body.
The term “full-spectrum” refers specifically to infrared light coverage, not the visible light spectrum. A full-spectrum infrared sauna combines shorter-wave near infrared with longer far wavelengths, giving you access to benefits that single-spectrum saunas cannot deliver on their own.
What Each Wavelength Does
- Near infrared (NIR, 700–1400 nm): penetrates the skin’s surface to support cell renewal and collagen production. This is the same wavelength range used in clinical photobiomodulation therapy.
- Mid infrared (MIR, 1400–3000 nm): reaches deeper into soft tissue to improve circulation and ease joint stiffness.
- Far infrared (FIR, 3000 nm–1 mm): penetrates 1.5–2 inches into the body for deep heating, a full sweat, muscle recovery, and cardiovascular response. Far infrared is the most studied wavelength for sauna therapy.
A full-spectrum sauna combines all three in every session. A far-infrared-only sauna delivers deep heating but misses the near and mid infrared benefits.
Full-Spectrum or Far Infrared?
- Full-spectrum infrared — near, mid and far infrared combined, from surface-level cell renewal through deep-penetrating heating. Best for comprehensive wellness, recovery, skin comfort, and circulation in one session. Sun Home models: Equinox (2P, 3P), Eclipse (2P, 4P), Luminar (2P, 5P).
- Far infrared only — far infrared alone (3000 nm–1 mm), deep-core heating at 1.5–2 inches of penetration. Best for deep heating, muscle recovery, and cardiovascular response. Sun Home models: Solstice (1P, 2P, 3P, 4P).
The Eclipse line adds integrated red light therapy alongside the full-spectrum heaters, for multi-therapy sessions that combine infrared heat with photobiomodulation in a single cabin.
Sun Home Full-Spectrum Models
Equinox Line (Indoor, Full-Spectrum)
The Equinox 2-Person and 3-Person use full-spectrum infrared heaters in hand-selected, kiln-dried eucalyptus cabins. Both run on 120V with a dedicated 20A circuit (NEMA 5-20P plug into a NEMA 5-20R receptacle) and reach a maximum of 165°F, averaging around 150°F in normal use.
Independent Vitatech testing measured 0.3–0.9 mG at the typical seated distance of three feet. ETL and ETL-C certified. Backed by a 7-year residential warranty on cabinetry and heaters, 3 years on controls.
Eclipse Line (Indoor, + Red Light)
The Eclipse 2-Person and 4-Person combine full-spectrum infrared with integrated red light therapy for multi-therapy sessions. Built with Canadian Hemlock interiors and patented EMF/ELF shielding.
The Eclipse 2P has 8 heaters (6 far-infrared + 2 full-spectrum) producing 2,820W total power and reaching 165°F. The Eclipse 2P runs on 120V with a dedicated 30A circuit (NEMA L5-30P plug into a NEMA L5-30R receptacle); the Eclipse 4P requires 240V on a dedicated 30A circuit (NEMA L6-30P plug into a NEMA L6-30R receptacle). A licensed electrician is required. Backed by a Limited Lifetime Warranty.
Luminar Line (Outdoor, Full-Spectrum)
The Luminar 2-Person and 5-Person outdoor saunas pair a Canadian Red Cedar interior with an aerospace-grade aluminum exterior shell for year-round durability in any climate. Both reach temperatures up to 170°F — the highest of Sun Home’s infrared saunas.
Both require 240V on a dedicated GFCI circuit; the Luminar 2P runs on a 20A dedicated circuit (NEMA L6-20P plug into a NEMA L6-20R receptacle), and the Luminar 5P requires a 30A dedicated circuit (NEMA L6-30P plug into a NEMA L6-30R receptacle). A licensed electrician is required for all 240V installs — failure to use a dedicated GFCI circuit voids the warranty. A red light therapy tower is available as an add-on. Backed by a Limited Lifetime Warranty.
Safety, EMF, and Technical Specs
EMF and Safety Certifications
Independent Vitatech testing (January 2025) measured 0.6–4.0 mG at one foot from the heater, 0.4–1.8 mG at two feet, and 0.3–0.9 mG at the typical seated distance of three feet — around background level, and well below a toaster (3–70 mG) or a hair dryer (60–200 mG). Vitatech places Sun Home in the lowest EMF tier of premium infrared sauna manufacturers. The Eclipse line adds patented EMF/ELF shielding technology. All Sun Home infrared saunas are ETL and ETL-C certified, confirming compliance with North American electrical safety standards.
Electrical Requirements
All models require a dedicated circuit, not a shared household 15A outlet. Circuit size is model-specific: the Equinox 2P and 3P run on 120V with a dedicated 20A circuit (NEMA 5-20P plug into a NEMA 5-20R receptacle). The Eclipse 2P runs on 120V with a dedicated 30A circuit, a NEMA L5-30P plug into a NEMA L5-30R receptacle (23.5A draw at 2,820W).
The Luminar 2P is 240V on a dedicated 20A circuit (NEMA L6-20P plug into a NEMA L6-20R receptacle). The Eclipse 4P (22A draw) and the Luminar 5P (30A draw) both require a 240V 30A dedicated circuit with a NEMA L6-30P plug into a NEMA L6-30R receptacle. A licensed electrician is required for all 240V and 30A installations.
Construction and Assembly
Sun Home full-spectrum infrared saunas use a tool-free Magne-Seal panel-locking system; panels snap together without power tools, nails, or clips. Assembly needs a minimum of two people.
All panels are kiln-dried and air-dried, using only ultra-low-VOC adhesives and non-toxic wood treatments — independently VOC-tested at 27 µg/m³ TVOC (VERT Environmental, AIHA-accredited). A separate adhesive test by Applied Technical Services (report #486424, June 2026) found no formaldehyde, benzene, toluene, ethylbenzene, or xylenes above the laboratory’s reporting limits, with total VOC content below 0.001% by weight.
