EMF Emissions
Winner: Clearlight Sanctuary 2 (0.05 mG vs 0.5 mG)
This is Clearlight's decisive advantage. At 0.05 milliGauss, the Sanctuary 2 has essentially zero EMF — achieved through their proprietary shielding that cancels electromagnetic fields at the heating element level. The Sunlighten mPulse measures 0.5 mG, which is still well below the Swedish safety standard of 3 mG, but it's 10× higher than Clearlight. For EMF-sensitive buyers, Clearlight is the clear choice.
Heater Technology
Winner: Depends on your priority
Clearlight's True Wave heaters combine carbon and ceramic elements. The carbon provides wide, even surface coverage while the ceramic delivers deeper, more intense infrared output. Together they create consistent heat without cold spots.
Sunlighten's SoloCarbon 3-in-1 is the only heater that can deliver near-infrared (0.7-1.4μm), mid-infrared (1.4-3μm), and far-infrared (3-100μm) wavelengths independently. This means you can run a near-infrared session for skin health, a mid-infrared session for circulation, or a far-infrared session for deep detox. No other brand can do this.
Warranty & Long-Term Value
Winner: Clearlight (Lifetime vs 7 years)
Clearlight's lifetime warranty covers heaters, electrical components, wood, and controls — for residential and commercial use. At $6,799 with a lifetime warranty, the total cost of ownership over 10+ years is exceptional. Sunlighten's 7-year warranty is reasonable but not industry-leading. At $7,200 with a 7-year warranty, there's a risk of unwarrantied repairs in years 8-15.
Build Quality & Materials
Winner: Tie
Both use premium construction. Clearlight offers a choice of Western Red Cedar (aromatic, naturally rot-resistant) or Basswood (hypoallergenic, lighter). Sunlighten uses Basswood exclusively. Both feature tongue-and-groove panels, tempered glass doors, and quality hardware. Assembly is similar — about 30-60 minutes with two people.
