Most people who search for a Clearlight review have already decided they want a premium infrared sauna. What they actually want to know is: what am I really getting for this price, and is there anything the brand isn’t telling me?
This review answers both questions with verified specs and real user feedback — not marketing language.

Why Clearlight Saunas Cost More Than Most Brands
True Wave Heaters: 360-Degree Coverage at 9.4 Microns
Most infrared saunas put heaters on the back wall and maybe the sides. Clearlight covers every surface — back wall, side walls, front wall, behind your calves, and under the floor.
You’re not sitting in front of a heat source. You’re surrounded by it.
The heater technology is patented: True Wave combines carbon fiber panels with ceramic rods in a single unit. Carbon produces broad, even infrared across a wide surface area. Ceramic boosts output intensity. The result is infrared at 9.4 microns — the wavelength at which human tissue absorbs infrared most efficiently.
Clearlight was also the first company to independently test and publish low-EMF heater data, setting the standard that other brands now compete against.
Temperature Philosophy: Lower Is Intentional
Clearlight’s 125–145°F / 52–63°C ceiling looks modest next to brands like Sun Home Equinox (165°F / 74°C).
That’s a design choice, not a limitation.
Clearlight is built around infrared output quality over air temperature. At 110–130°F / 43–54°C, their True Wave heaters deliver deep infrared penetration with less thermal stress — allowing longer, more comfortable sessions. The experience feels more like sitting inside radiant warmth than being blasted by hot air. UCSF clinical research on infrared sauna use and depression was conducted at these temperatures, not at 165°F.
If you’re comparing temperature ceilings and feeling like Clearlight “loses” — you’re measuring the wrong variable for what this sauna is designed to do.
EMF and ELF: Still the Industry Benchmark
Clearlight pioneered low-EMF infrared saunas 25+ years ago and remains the benchmark.
Their shielded metal conduit wiring and back-to-back heater configuration cancel magnetic fields at the source. VitaTech Electromagnetics testing confirms below 1 mG at the heater surface, virtually zero at the seated position. ELF measures ~200 mV — five times below the 1,000 mV threshold of concern.
Unshielded competitor saunas often measure 20x above that threshold.
Limited Lifetime Warranty: The Real Thing
Clearlight’s Limited Lifetime Warranty covers everything — heaters, controls, electrical, and wood cabinetry — for as long as you own the sauna (residential use).
True Wave heaters have an estimated operational life of 30,000 hours. At five sessions per week, that’s over 100 years of use. This is a genuinely rare warranty in any product category.
Wood Quality: Built to Not Warp
Every Clearlight cabin uses wood kiln-dried and air-dried to 7% moisture content, with each panel pressed to prevent warping over time. The sauna is fully assembled and tested at the factory before being disassembled and shipped — so what arrives has already been quality-checked running at temperature.
Is Clearlight Sanctuary Worth the Extra Money?
This is where most buyers get confused — and where Clearlight’s marketing creates the most misaligned expectations.
Sanctuary adds full-spectrum heaters on the front wall to the standard far-infrared setup. These emit near, mid, and far infrared simultaneously. Near infrared is associated with skin health and surface tissue repair. Far infrared penetrates deeper into muscle and circulation.
What the marketing implies but doesn’t state directly: Sanctuary’s near-infrared output comes from quartz halogen heaters peaking around 1,650 nanometers — primarily deep thermal infrared, not the 630–850nm wavelengths used in dedicated red light therapy devices. Buyers expecting Sanctuary to deliver photobiomodulation (PBM) benefits are often disappointed.
If your goal is heat therapy, relaxation, and verified low-EMF performance, Premier does the job at $2,000–$5,000 less. If you specifically want full-spectrum and understand what it does and doesn’t include, Sanctuary is a well-built way to get it.
The Pricing Transparency Problem
Clearlight doesn’t publish prices on their website. You have to request a quote and talk to a sales rep.
This is deliberate — it allows dealer pricing flexibility and prevents easy comparisons. Multiple buyers report that initial quotes differ substantially from final prices once delivery, installation, and add-ons are factored in.
Authorized dealer pricing gives you a baseline: Premier IS-2 runs approximately $5,299–$6,099. Sanctuary 2-person approximately $6,800–$7,600.

Who Should Buy Clearlight
- EMF and ELF performance are a genuine priority — not just a checkbox
- You plan daily or near-daily use and want a lifetime warranty that means something
- You want the most established brand in premium infrared saunas — 25+ years, clinical research, doctor-designed
- You’re comfortable navigating a sales-call buying process
- Budget is $5,000+ and you’re thinking about 10+ year ownership
Who Should Look Elsewhere
- You want transparent online pricing before talking to anyone
- You’re buying your first sauna and aren’t sure how often you’ll use it
- You want full-spectrum for red light therapy benefits — Sanctuary’s heaters don’t deliver PBM wavelengths
- Budget is under $4,000 — JNH or Dynamic offer legitimate far-infrared at a fraction of the cost
- You want the highest max temperature — Clearlight’s ceiling is lower than Sun Home Equinox (165°F / 74°C) by design

Real Ownership Reality
Clearlight isn’t the hottest sauna on the market.
It isn’t the cheapest. And it definitely isn’t the most transparent buying process.
But long-term owners rarely replace them.
That’s the real reason this brand still dominates the premium infrared sauna market after 25+ years — not marketing, not endorsements. It’s the combination of heater quality, EMF performance, and a lifetime warranty that actually means something. Buyers who use it daily for years consistently feel the premium was justified. Buyers who use it twice a week sometimes don’t.
That’s the honest version of the Clearlight story.

FAQ
Is Clearlight worth the price?
For daily users who prioritize verified low-EMF performance and want a lifetime warranty, yes. The True Wave heater technology, 360-degree coverage, and 25+ years of clinical research backing are real differentiators. For occasional users or first-time buyers, the premium is harder to justify — JNH delivers legitimate far-infrared performance at a fraction of the cost.
What’s the difference between Premier and Sanctuary?
Premier uses far infrared only via True Wave carbon-ceramic heaters covering all walls, calves, and floor. Sanctuary adds full-spectrum heaters on the front wall that emit near, mid, and far infrared. The cabin construction and base heater setup are identical. The Sanctuary premium is $2,000–$5,000+ depending on model. Worth it if you specifically want full-spectrum wavelengths — not worth it if you’re expecting red light therapy benefits, which Sanctuary’s heaters don’t deliver at therapeutic PBM wavelengths.
Does Clearlight require a dedicated circuit?
It depends on the model. Premier IS-1 and IS-2 run on a standard 120V / 15A outlet. IS-3 and IS-C require a dedicated 120V / 20A circuit. Sanctuary 1 runs on 15A; Sanctuary 2 requires 20A; Sanctuary 3 and larger require 240V. Always verify with the official electrical requirements page before purchasing.
How does Clearlight’s EMF compare to other brands?
Clearlight’s EMF performance is among the lowest in the industry — virtually zero at the seated position per VitaTech Electromagnetics testing. ELF measures ~200 mV versus a 1,000 mV threshold of concern. They were the first company to independently test and publish these results, setting the standard others now try to match.
What does Clearlight’s Lifetime Warranty actually cover?
Everything — heaters, controls, electrical components, and wood cabinetry — for as long as you own the sauna in residential use. Full details at Clearlight’s warranty page.
