Clearlight Sanctuary 2 — Full-Spectrum Infrared Sauna

The full-spectrum infrared sauna with the lowest EMF readings in the category — and the brand Jacuzzi acquired specifically because of its tech moat.

Clearlight Sanctuary 2 is the sauna for buyers who care about two specific specs more than anything else: full-spectrum heater coverage and ultra-low EMF emissions. The True Wave heaters deliver near, mid, and far infrared simultaneously (similar to Sunlighten's Solocarbon), but Clearlight has been the EMF-leader benchmark for over a decade — typically reading under 1 mG at body level versus 3-5 mG on most competitors.

The Jacuzzi acquisition (2021) is what tipped the balance for many premium buyers. Pre-acquisition, Clearlight was a strong but smaller brand competing against Sunlighten on premium positioning. Post-acquisition, the warranty backing, dealer network, and parts-availability matched Sunlighten's, while preserving Clearlight's lifetime warranty (which Sunlighten doesn't match across the cabin).

The Sanctuary 2 specifically targets the 2-person buyer who wants more space than a Solo but isn't ready for a 3-4 person room. Configurations scale up to Sanctuary 5 for buyers wanting outdoor-capable or family-sized installs.

Where Sunlighten still wins: the research footprint. Mayo Clinic and peer-reviewed studies cite Sunlighten's Solocarbon technology specifically; Clearlight's True Wave hasn't accumulated the same academic citation base. For buyers who care about academic validation, that's a real point.

Where Clearlight wins: the EMF spec, the lifetime warranty, and the Jacuzzi-backed long-term support. For buyers in tight rooms (where EMF exposure adds up over hundreds of sessions) or those installing once for a 15-year horizon, Clearlight is the conservative-correct pick.
