Irradiance in context

The GembaRed Rex 2.0 lists 5 mW/cm² at 6 inches. Measurement note: Third-party lab, spectrometer peaks; honest low figures Pairing surface reds (630nm, 660nm) with deeper near-infrared (830nm, 850nm), it covers both skin-level use and deeper muscle or joint targets. Check this figure at your real distance with the dose calculator, aiming for a studied 10 to 60 J/cm² range; if the number is method-unstated or solar-meter based, treat roughly half of it as the working value.
