Two of the best-known premium infrared brands. Clearlight publishes prices on a separate price list; Sunlighten makes you ask. Here's how their 2-person models compare on everything they do publish.
On paper they're very close: same outlet, same footprint, similar power. Clearlight wins on warranty (lifetime residential vs Sunlighten's 7 years on cabinet and heaters). Sunlighten publishes more detail: assembly time, a named EMF tester, and full spec sheets, but no price: ask for a written quote and compare it with Clearlight's listed price.

Clearlight: "True Lifetime Warranty" (residential).
Sunlighten: 7 years on cabinetry and heaters, 3 years on controls, 1 year on glass doors and audio.
Clearlight: mahogany or basswood.
Sunlighten: basswood or eucalyptus.
Both sell full-spectrum heating. Clearlight lists heaters on the back and side walls, behind the calves and under the floor. Sunlighten's Amplify II adds three high-intensity full-spectrum heaters and reaches 170°F.
Sunlighten says 1–2 hours with two people for the Believe. Clearlight says "easy assembly" without a time.
Both need a dedicated 120V / 20A circuit with a NEMA 5-20 plug, draw about 2.3 kW, measure roughly 51" × 46–48" × 77–79", and ship free. Running cost is about the same: up to $0.31 a session for the Clearlight.
Plenty of other 2-person cabins publish prices, some on a standard outlet. See the infrared comparison.
On published specs they're close: both 2-person cabins need a dedicated 120V / 20A outlet, are about the same size, and draw about 2.3 kW. Clearlight's lifetime residential warranty is the clearest difference; Sunlighten gives 7 years on cabinet and heaters.
Clearlight lists its prices on a separate price list: the Sanctuary 2 was $7,299 in basswood when we checked.
Both claim low EMF. Sunlighten says its mPulse Believe was tested by Vitatech Electromagnetics; Clearlight says its heaters cancel EMF and ELF. We haven't measured either.
Each opened on 2 November 2026. Prices change often, especially around sales.
