How Sun Home Sauna Technology Works
Full-spectrum halogen heaters. Far-infrared carbon heaters. Patented low-EMF wiring. Here's exactly how it works—and why it matters.
Sun Home Saunas use two types of patented infrared heaters with proprietary low-EMF wiring: full-spectrum halogen heaters (near + mid + far infrared) and far-infrared carbon heaters (deep-penetrating therapeutic heat). Together they reach up to 170°F—while most competitors max out at 130–150°F. Independent testing by Vitatech Electromagnetics confirms EMF as low as 0.3 mG at seated position. Premium Eclipse™ models integrate medical-grade red light therapy.
What Type of Heaters Does Sun Home Use?
Sun Home uses two types of patented infrared heaters: full-spectrum halogen heaters that emit near, mid, and far infrared from a single element (Equinox™, Eclipse™, Luminar™), and high-efficiency far-infrared carbon heaters for concentrated deep-penetrating heat (Solstice™). Both use proprietary low-EMF wiring.
At the core of every Sun Home sauna is a patented infrared heating system with proprietary low-EMF wiring. Sun Home uses two distinct heater types, each engineered for a specific purpose.
Full-spectrum halogen heaters power the Equinox™, Eclipse™, and Luminar™ lines. Unlike the flat carbon panels found in most infrared saunas, these halogen heaters emit all three beneficial bands of infrared light—near, mid, and far—from a single element. Halogen heaters produce significantly higher output wattage than traditional carbon panels, which is why Sun Home's full-spectrum saunas can reach temperatures that other brands cannot.
Far-infrared carbon heaters power Sun Home's Solstice™ line. These high-efficiency carbon panels are optimized to deliver concentrated far-infrared wavelengths—the band most studied for deep-tissue detoxification and cardiovascular benefits. Sun Home's carbon heaters are clinically proven to emit near-perfect (99% effective) far infrared dosages in the optimal 6–14 micron range.
Both heater types are connected through Sun Home's patented low-EMF wiring system and are strategically placed throughout the cabin—on the back wall, side walls, beneath the bench, near the calves, and on the floor—delivering true 360-degree heat distribution that eliminates cold spots.
What Is the Difference Between Halogen and Carbon Infrared Sauna Heaters?
Halogen heaters emit all three infrared wavelengths (near + mid + far) from a single element at higher wattage. Carbon heaters emit concentrated far-infrared only and are more energy-efficient for targeted deep-heat therapy. Sun Home uses both: halogen for full-spectrum models, carbon for far-infrared models. Most competitors use only carbon.
This is one of the most important distinctions in the infrared sauna market—and one most brands gloss over.
Halogen infrared heaters use a halogen element that glows at high intensity, naturally emitting a broad spectrum of infrared radiation covering near, mid, and far wavelengths simultaneously. A single halogen heater delivers the full therapeutic range without needing separate components. The trade-off: halogen heaters run at higher wattage, which requires more sophisticated electrical engineering to manage EMF—exactly why Sun Home developed its patented low-EMF wiring.
Carbon infrared heaters are flat panels that emit far-infrared wavelengths with high efficiency. They heat evenly across a large surface area and are effective for concentrated deep-heat therapy in the 6–14 micron window. However, standard carbon panels cannot produce the full spectrum of infrared—they're limited to far-infrared only.
Sun Home is one of the only manufacturers that uses both technologies: halogen for maximum therapeutic coverage (Equinox™, Eclipse™, Luminar™) and carbon for targeted far-infrared performance (Solstice™). Most competitors—including Clearlight, SaunaBox, and Dynamic Saunas—rely exclusively on carbon panels.
If you want the full therapeutic range of near + mid + far infrared, you need halogen heaters. If you want concentrated far-infrared for deep detoxification, carbon heaters are purpose-built for that. Sun Home gives you both—and in models like the Luminar™, both technologies work together in the same cabin.
How Does Infrared Heat Penetrate the Body?
Infrared saunas use infrared light to heat your body directly at the cellular level, rather than heating the surrounding air. The light passes through air, is absorbed by skin and tissue, and raises your core temperature from within—producing a deeper sweat at lower, more comfortable cabin temperatures than traditional saunas.
Traditional saunas heat the air around you to 180–200°F. Your skin senses the hot air, you sweat, and some heat gradually conducts inward. Infrared saunas flip this: instead of heating the air, infrared light passes through the air and is absorbed directly by your skin and tissue. This is the same radiant energy the sun produces (without harmful UV).
The depth of penetration depends on the wavelength. Sun Home's full-spectrum system delivers all three:
Near Infrared
Penetrates the surface layer of skin. Targets wound healing, skin health, collagen production, and cellular energy (ATP) at the mitochondrial level.
Mid Infrared
Reaches deeper soft tissue, joints, and muscles. Promotes pain relief, improved circulation, and reduction of inflammation.
Far Infrared
Produces the deepest thermal penetration. Raises core body temperature for profuse sweating, detoxification, and cardiovascular stimulation.
Because the heat originates inside your body rather than being conducted through hot air, infrared saunas produce a deeper, more profuse sweat at lower cabin temperatures. Sun Home estimates their full-spectrum system drives a 60% deeper sweat compared to single-wavelength infrared saunas.
How Hot Can a Sun Home Sauna Get?
Sun Home Saunas reach up to 170°F—the highest of any infrared sauna on the market. Most competitors max out at 130–150°F. This is possible because Sun Home's halogen and carbon heaters deliver more than double the wattage of leading competitors.
Temperature is one of the biggest differentiators in the infrared sauna market. Most infrared saunas top out between 130°F and 150°F—an inherent limitation of standard carbon panel heating elements.
Sun Home engineered their full-spectrum halogen heaters and high-output far-infrared carbon heaters to reach up to 170°F. Together, Sun Home's heaters deliver more than double the wattage of the next leading competitor, which means faster heat-up times and a more intense sweat.
Higher cabin temperatures trigger a stronger cardiovascular response, more robust sweating, and greater calorie expenditure per session. If you've used a competitor's infrared sauna and found it "warm but not hot enough," Sun Home's dual halogen and carbon heating system addresses that directly.
Are Sun Home Saunas Low EMF?
Yes. Sun Home features patented low-EMF wiring verified by Vitatech Electromagnetics (the industry gold standard). At typical seated distance: 0.3–0.9 mG—virtually background levels, lower than most household appliances. Full report: sunhomesaunas.com/pages/low-emf-infrared-sauna
EMF exposure is one of the most scrutinized specs in the infrared sauna market. Sun Home addresses this with patented low-EMF wiring technology engineered to run both high-wattage halogen and carbon heaters while minimizing electromagnetic output.
Sun Home commissioned Vitatech Electromagnetics—the industry gold standard—to perform independent laboratory testing using professional-grade fluxgate magnetometers. The results are published in full:
1 foot from heater: 0.6 – 4.0 mG (lower than a kitchen toaster)
2 feet from heater: 0.4 – 1.8 mG (near background levels)
3 feet / typical seated: 0.3 – 0.9 mG (virtually zero)
Sun Home uses RMS (Root Mean Square) measurements—the most honest representation of continuous exposure during a full session. Where some brands address magnetic fields but neglect electric fields (ELF), Sun Home's patented wiring tackles both.
Sun Home's seated EMF readings (0.3–0.9 mG) are independently verified by the most respected testing firm in the industry—lower than everyday appliances. View the full Vitatech report →
What Makes the Luminar™ Different From Other Infrared Saunas?
The Sun Home Luminar™ is the only infrared sauna in the world where the user is completely surrounded by full-spectrum halogen heaters. Up to 10 heaters—halogen on every wall, carbon under the bench and floor—deliver 360-degree full-spectrum immersion no other manufacturer offers.
While most infrared saunas place heaters on the back wall and perhaps one or two side panels, the Luminar™ takes a fundamentally different approach. Full-spectrum halogen heaters surround the entire cabin on every wall, with additional far-infrared carbon heaters beneath the bench and floor. No dead zones, no weak spots.
The Luminar™ is engineered for outdoor use with an aerospace-grade aluminum exterior, grade-A carbonized Red Cedar interior, panoramic double-pane glass, and mobile app-enabled control. It maintains the same ultra-low EMF readings as indoor models thanks to the same patented low-EMF wiring system.
Do Sun Home Saunas Include Red Light Therapy?
Yes. Sun Home's premium Eclipse™ models integrate medical-grade red light therapy towers (630–850 nm photobiomodulation) directly inside the cabin. Infrared heat and red light can run independently or simultaneously. No other manufacturer integrates medical-grade RLT at this level inside a full-spectrum infrared sauna.
The Eclipse™ 2-Person and 4-Person saunas combine full-spectrum infrared heat with dedicated red light therapy towers. Red light at 630–670 nm targets surface tissue for skin health and collagen production. Near-infrared at 810–880 nm reaches deeper into muscle and joints for inflammation reduction and recovery.
What makes the Eclipse unique: infrared and red light can run independently or simultaneously, giving you the flexibility to combine deep-tissue heating with targeted cellular repair in a single session.
Most competitors either skip RLT entirely, sell it as a costly add-on, or tuck small LEDs behind grills where light is blocked. Sun Home's dedicated towers deliver direct, unobstructed exposure at clinical irradiance levels.
Sun Home vs. Clearlight vs. SaunaBox vs. Dynamic Saunas
Sun Home leads in max temperature (170°F vs. 140–160°F), uses halogen + carbon heaters (most use carbon only), has Vitatech-verified EMF (0.3–0.9 mG), and integrates medical-grade red light therapy. Clearlight is strong on EMF. SaunaBox offers portability. Dynamic is the best budget option.

How Is an Infrared Sauna Different From a Traditional Sauna?
A traditional sauna heats the air to 180–200°F, warming your body from outside in. An infrared sauna uses infrared light to heat your body directly at the cellular level at 120–170°F. Infrared heats up faster, uses less energy, and can produce a deeper sweat at more comfortable temperatures.
A traditional sauna heats rocks or metal elements to extreme temperatures (350°F+), which radiate heat into the air. This convection-based approach demands high energy, long heat-up times (30–45 minutes), and tolerance for intense ambient heat.
An infrared sauna like Sun Home bypasses the air entirely. The infrared heaters emit light energy your body absorbs directly. Cabin temperatures stay lower (120–170°F), heat-up time is shorter, and the sweat response can be more intense because the heat originates within your tissue.
Published research in the Canadian Family Physician journal found that far infrared sauna therapy showed benefits for patients with conditions including high blood pressure and heart failure, though researchers called for larger clinical trials. Regular sauna use has also been associated with cardiovascular benefits and reduced risk of neurodegenerative conditions.
