Clearlight Infrared
Doctor-designed low-EMF infrared saunas with the longest premium track record
Key Features
Sanctuary Series Full-Spectrum Heaters
The Sanctuary line combines true near, mid, and far infrared in a single cabin using carbon-ceramic and dedicated near-infrared LEDs — one of the few residential brands delivering all three wavelengths without an upcharge module.
True Wave Low-EMF Heating Panels
Clearlight publishes third-party EMF and ELF readings measured at the body in milligauss, and their True Wave panels consistently test below 1 mG — the most conservative independently verified safety profile in the residential infrared category.
Lifetime Residential Warranty
Every Clearlight residential sauna ships with a lifetime warranty on the cabin, heaters, and electronics — the strongest warranty coverage offered by any major infrared brand and a meaningful indicator of build confidence.
Doctor-Founded Brand Heritage
Founded in 1997 by chiropractor Dr. Raleigh Duncan, Clearlight has the longest continuous operational history of any premium US infrared sauna brand and has been the de facto reference design for the category for over two decades.
Strengths
- Lifetime warranty on cabin, heaters, and electronics is the strongest in the infrared category
- Independently verified low-EMF True Wave heaters consistently measure below 1 mG at the body
- Sanctuary full-spectrum models include true near-infrared without a paid upgrade
- Berkeley headquarters and 25+ year operational history provide unusual continuity for the category
Considerations
- Premium pricing places entry-level Sanctuary models at roughly twice the cost of comparable imports
- Cabin sizes above 2-person require a hardwired 240V circuit and licensed electrical work
- Smaller clinical research footprint than Sunlighten — fewer published wellness program studies
Our Verdict
“Clearlight set the benchmark for the premium residential infrared category and the Sanctuary series remains the strongest argument for the brand today. The combination of true full-spectrum heaters, independently verified low-EMF readings, and a lifetime warranty is genuinely unmatched in the segment. The trade-off is price — entry-level Sanctuary cabins start at roughly twice the cost of a comparable imported infrared sauna, and buyers on a tighter budget may find the value gap difficult to justify without a clear long-term usage commitment.”
