- Five of six tracked masks state irradiance in FDA 510(k) filings, while only four publish a buyer-facing figure.
Field notes
The project separates buyer-facing claims from figures found in FDA 510(k) submissions, then plans to test the hardware itself. Its six-device table records wavelengths, claimed irradiance, price, and measurement status, while four linked trials provide protocol, effect, sample-size, and funding details. The site explicitly declines to estimate results before its measurement rig is ready, making the unfinished comparison part of the visible record.
