The short version

Three premium IR saunas with three different philosophies. Sunlighten on programmable full-spectrum, Clearlight on Jacuzzi-backed combined full-spectrum, SaunaSpace on near-IR-only with Faraday-cage shielding. All three premium-tier; pick on which philosophy fits your IR-sauna goal.

When Sunlighten mPulse is the right pick

For users wanting programmable per-wavelength control (near / mid / far separately), FDA Class II registration and the deepest published-research footprint. The category reference for premium full-spectrum.

When Clearlight Sanctuary 2 is the right pick

For users wanting Jacuzzi-backed lifetime heater warranty and full-spectrum IR at the most accessible price in the premium tier. The hypoallergenic basswood option is unique.

When SaunaSpace Faraday is the right pick

For users specifically wanting near-IR-only via tungsten-filament incandescent bulbs and full Faraday-cage EMF shielding. The biohacker premium for near-IR purists.

Common questions

Which premium IR sauna is best?

Sunlighten mPulse for programmable full-spectrum and deepest research footprint. Clearlight Sanctuary 2 for Jacuzzi-backed warranty and best value in the tier. SaunaSpace Faraday for near-IR-only and full Faraday-cage EMF shielding. Three philosophies, three premium picks.

Is full-spectrum IR better than near-IR-only?

Different bets. Full-spectrum delivers heating across near, mid and far wavelengths — broader thermal effect. Near-IR-only (SaunaSpace) targets the wavelengths closer to natural sunlight, with stronger penetration into deeper tissues. SaunaSpace bets on spectrum specificity; Sunlighten and Clearlight bet on spectrum breadth.

Does the EMF difference between these matter?

For users specifically prioritising EMF discipline — SaunaSpace’s Faraday cage is in a class of its own. For most users — Sunlighten and Clearlight’s documented low EMF (<1 mG) is more than adequate.

Which has the deepest research backing?

Sunlighten — the brand has the largest published-research footprint in consumer IR sauna by a meaningful margin. Clearlight and SaunaSpace have research presence but smaller volume of device-specific studies.

Are warranties comparable?

Clearlight wins on paper with lifetime heater warranty (Jacuzzi backing). Sunlighten: 7-year. SaunaSpace: 5-year. In practice premium IR sauna heaters in any of these brands rarely fail before 10–15 years.
