Question: Due to possible harmful radiation, what requirements are to be applied to LEDs?8 u9 N! m) W3 C' o+ F ~2 h+ A

in order to avoid expensive measurements, luminaires provided with LEDs

- If the light intensity is low, i.e. from a conventional LED for indication or signalling$ x0 g$ a6 B8 q# \
purposes, the LED is most likely comparable with a laser of Class 1 according to IEC/EN
