What Makes a Panel Worth Buying

Verified irradiance. Only third-party spectroradiometer-measured irradiance should be trusted. Solar meters overestimate RLT output by 20–50%. The independent tests compiled by resources like GembaRed and Outliyr consistently show that many manufacturers significantly over-claim their irradiance at treatment distance. PlatinumLED and Joovv publish verifiable third-party data; many competitors do not.

Wavelength accuracy. Research-backed wavelengths are 630–680nm (red) and 800–880nm (NIR). A device claiming 660nm that actually emits at 675nm is outside the studied range. Independent testing has found 41% of budget devices emit more than 15nm outside their stated wavelengths.

EMF documentation. Panels operated close to the body for daily sessions should have published EMF measurements. PlatinumLED and Joovv publish this; Mito Red publishes partial data. Budget brands typically publish nothing.
