8 M$ g6 Z5 [$ T( t/ J7 vDecision: In principle apply the requirements given in IEC/EN 60825-1. However in order
to avoid expensive measurements, the luminaires provided with LEDs should be
treated in the following:

- If such a declaration cannot be provided or if we are insecure on how to judge, the
