Irradiance in context
The GembaRed Improve v1.1 lists 5 mW/cm² at 6 inches. Measurement note: Third-party lab, spectrometer peaks; honest low figures With both surface reds (630nm, 660nm) and deeper near-infrared (810nm, 830nm, 850nm), it is built to cover skin-level and deeper muscle or joint work. Run your real distance and this figure through the dose calculator to land inside 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.
