Who should buy which
Buyers prioritizing ultra-low EMF, lifetime warranty, and Jacuzzi-backed long-term support — particularly those installing in smaller rooms where EMF accumulates.
You want Mayo Clinic-cited heater research (go Sunlighten), or you need outdoor installation (Sun Home Luminar is the better fit).
Buyers who want a credible heritage-brand far-infrared sauna with lifetime heater warranty and the largest service network in the category — and who don't need near or mid infrared in the same cabin.
You want full-spectrum (near + mid + far) in one cabin (move to mPulse), you live in an apartment without 220V access for 2-person+ cabins, or you can't justify $4K+ over a sauna blanket.
