Clearlight sells infrared cabins in two indoor lines: the far-infrared Premier and the full-spectrum Sanctuary, which adds 500W full-spectrum heaters on the front wall. Both use Clearlight's True Wave heaters, which it says combine carbon and ceramic, including one under the floor.
The Sanctuary Outdoor 2 and 5 are its outdoor-rated cabins, with a weather-resistant exterior and a cover. The Sanctuary Retreat is built for wheelchair access, and The Curve is a lie-down dome that sits over Clearlight's infrared PEMF mat. HigherDOSE says its infrared sauna is powered by Clearlight.

Before you order from Clearlight
- The smallest cabins plug into ordinary outlets: Premier IS-1 and IS-2 and Sanctuary 1 into a standard 120V 15A outlet, Premier IS-3 and Sanctuary 2 into a 120V 20A outlet. Sanctuary 3 and up, the corner model and both outdoor models need a 240V outlet (NEMA 6-15 or 6-20).
- Outdoor sizes are listed with and without the roof cap, which overhangs 9 in. Plan the base for the larger figure.
- The Sanctuary 5 is named for five, but Clearlight's own description says it fits up to 4 adults.
- Clearlight says its heaters cancel out both EMF and ELF. If EMF matters to you, ask for the measurement method and distance.

Frequently asked questions
Does Clearlight make outdoor saunas?
Yes. The Sanctuary Outdoor 2 and Sanctuary Outdoor 5 are full-spectrum infrared cabins with a weather-resistant DriftwoodTec exterior, a mahogany interior and an included outdoor cover. Both need a 240V outlet.
What is the difference between Clearlight Premier and Sanctuary?
The Premier is far infrared only. The Sanctuary is full spectrum: it adds 500W full-spectrum heaters on the front wall to the far-infrared heaters around the walls, calves and floor.
Do Clearlight saunas need a dedicated circuit?
Clearlight says the Premier IS-1 and IS-2 and the Sanctuary 1 plug into a standard household outlet. Larger models need a 120V 20A outlet or a 240V outlet, which in most homes means an electrician adds a circuit.
