01 / Our approach
How did we evaluate these products and services?
We compared the named models using company descriptions of their format, controls, power and installation. Engineering specifications describe the equipment; benefit claims remain the company’s claims.
What Are the Best Habits for Longevity?: evidence and sources02 / The takeaways
What did the source evidence show?
- Sunlighten and Clearlight use infrared heaters; Finnleo and Almost Heaven use traditional electric heaters with stones.
- The Hallmark 44 specifies 120 V plug-in power. Salem’s listed 6 kW heater requires 240 V hardwiring.
- A 120 V label does not settle the circuit requirement: Sanctuary 2 specifies a 20 A outlet.
What would the selected heater change about installation?
The products and services
What is distinct about each product or service?
The order is not a ranking. Each profile identifies the named model or clearly labeled model family.
These are company-described equipment differences. Numerical specifications refer to the identified model or configuration.
Product 01 / 04
Sunlighten mPulse Aspire — PulseIQ version
Equipment formatOne-person infrared cabin
Sunlighten describes Aspire as a one-person cabin with separate control of red light and near-, mid- and far-infrared output. The current PulseIQ version includes a tablet, app controls and preset programs. The company markets relaxation and recovery benefits.
The current generation’s installation instructions determine electrical supply and clearance. Earlier mPulse dimensions or power figures should not be assumed to describe the current cabin.
Product 02 / 04
Finnleo Hallmark 44
Equipment formatTwo-person traditional indoor sauna
Finnleo lists a 48-by-48-inch cabin, 80 inches high, with a Piccolo Mini traditional heater and stones. This exact Hallmark 44 uses 120 V plug-in power; larger Hallmark models have different requirements.
The company describes six-panel assembly, a built-in floor and Bluetooth audio. The model-specific installation instructions govern the outlet and circuit; a specification from another Hallmark size is not interchangeable.
Product 03 / 04
Almost Heaven Salem 2-Person Barrel Sauna
Equipment formatTraditional outdoor barrel sauna
Almost Heaven’s Salem listing describes a two-person barrel with a 6 kW electric heater and sauna stones. The heater requires a 240 V, 30 A hardwired supply; lighting has a separate plug-in requirement.
Heater and control choices affect the final installation. This outdoor barrel format differs from an indoor infrared cabin in its siting and heat system.
Product 04 / 04
Clearlight Sanctuary 2
Equipment formatTwo-person infrared cabin
Clearlight describes full-spectrum front heaters and far-infrared heaters around the cabin. Its US Sanctuary 2 specification lists 120 V power with a 20 A outlet and NEMA 5-20P plug, rather than an ordinary 15 A socket.
The company lists an exterior about 51¾ inches wide, 47¾ deep and 77 high, with additional clearance around an enclosed installation. The red-light tower is an optional upgrade, not an assumed part of the base cabin.
How does a cabin’s capacity compare with the space and clearances it needs?
