According to IEC62471 non-GLS (general lighting services), the biosafety level of all light waves within 20 cm of the luminaire and between 280 and 1400 nm of the luminaire needs to be evaluated. (The assessed biosafety level needs to be Risk Group 0 (Exempt), Risk Group 1, or Risk Group 2; if the luminaire's replacement light source is fluorescent or HID, there is no need to assess the biophotonic safety rating.
