This review is a spec-and-price comparison built from the maker's public product pages. We have not tested these products.
The lineup
- Signature: far infrared from Sunlighten's SoloCarbon heaters, one-button control. The entry line.
- Amplify: full spectrum plus halogen heaters. Sunlighten calls it the hottest line and lists temperatures up to 170°F on its Amplify pages, "in ideal conditions."
- mPulse: red, near, mid and far infrared delivered separately, with programs. The most expensive line.
- Solo System: a portable, lie-down far infrared unit for one person.

Lowest listed configuration on each maker's store, checked Oct 27, 2026.
Most models showed a sale price against a higher regular price when I checked (for example, Signature II at $5,499 against $6,399). The Ice Barrel store lists the Amplify II at the same $5,999.
What is not published
The Sunlighten product pages I read do not list electrical requirements or exterior dimensions. Those decide whether a cabin fits your room and circuit, so ask Sunlighten for both before you order. Compare that with Sun Home, which lists 120V, 2,006 watts and a dedicated 20-amp circuit for its Solstice 2.
How it compares
At 2 people, the Signature II ($5,499) is cheaper than the Sun Home Solstice 2 ($6,199). The Amplify II ($5,999) is cheaper than the Clearlight Sanctuary 2 at a retailer ($8,957) for a full spectrum cabin. The best infrared sauna list puts them side by side.
