Clearlight Sanctuary 2 review

/ 10
The closest premium competitor to Sunlighten — full-spectrum IR, Jacuzzi-backed warranty, slightly cheaper.
Best for buyers wanting Sunlighten-tier full-spectrum IR with Jacuzzi backing at marginally lower cost.
Clearlight Sanctuary 2 is the Jacuzzi-owned premium IR sauna. Full-spectrum delivery (near + mid + far IR), basswood or red cedar cabin, third-party EMF measurement, lifetime warranty on heaters under Jacuzzi’s backing. Slightly less rigorous wavelength implementation than Sunlighten mPulse but at a marginally lower price.
How we tested: Evidence-based assessment — scored from Clearlight product documentation and independent 2026 reviews. Not hands-on tested by ONDA.
Full-spectrum IR via True Wave heaters — combined near, mid and far in single emitters (less granular than mPulse but credibly broad-spectrum).

Where it leads
Clearlight Sanctuary 2 is the closest premium competitor to Sunlighten mPulse. Full-spectrum IR delivery, Jacuzzi-owned brand backing with lifetime heater warranty, basswood or red cedar build, independently-measured low EMF, FDA Class II in some configs. Marginally cheaper than Sunlighten for comparable feature depth.
Where it falls short
The full-spectrum implementation combines wavelengths in single emitters rather than running separate near/mid/far systems like Sunlighten mPulse. Less granular control per session.
Who it is for
Choose Clearlight Sanctuary 2 if you want premium full-spectrum IR with Jacuzzi brand backing and marginally lower price than Sunlighten. For programmable per-wavelength control, mPulse is the right shape.
