Sunlighten mPulse Aspire vs Medical Saunas Medical 4
The mPulse is the clear pick: its full spectrum rests on a separate near-infrared LED emitter, and its EMF claim has no third-party report tied to the Aspire, so it earns no EMF credit, but it at least gives a number to check. The Medical 4 is listed as full spectrum on carbon and ceramic panels with no separate near-infrared emitter found, and we could not find a report behind its EMF number, so our scoring credits neither.
Both are marketed as full spectrum, but only one backs it. The Sunlighten mPulse delivers near-infrared from real 660 and 850 nm LEDs and Sunlighten cites a commissioned Vitatech EMF report that lists other Sunlighten models, not the Aspire; the Medical 4's full spectrum rests on carbon and ceramic panels, and we could not find a third-party report behind its headline 0.03 mG EMF claim.

FAQ
- Is the Medical 4's 0.03 mG claim credible?
- We could not confirm it. We found no published third-party report or stated measurement position behind the 0.03 mG figure. We treat it as an unsourced brand claim and cap the EMF dimension accordingly.
