  j7 y: u* T9 x9 DQuestion: Due to possible harmful radiation, what requirements are to be applied to LEDs?
Decision: In principle, apply the requirements given in IEC/EN 60825-1 (*)-(#). However
/ X& I7 T: d5 ^3 Pin order to avoid expensive measurements, luminaires provided with LEDs
7 G  b0 U/ {4 n  ~5 d, O8 dshould be treated as follows:
- If the light intensity is low, i.e. from a conventional LED for indication or signalling

with the limits given for Class 1 lasers in IEC/EN 60825-1 (*)-(#) and that no
4 j# P& W- E( a. R) @: m* lmeasurement is made.
- In all other cases the luminaire manufacturer shall be asked to provide a declaration based

! {! ]3 o; D  x" ZLED module does not exceed the values given in IEC/EN 60825-1 (*)-(#) for Class 1
or1M lasers with or without optics. In the TRF, it is indicated that judgement is based on
manufacturer’s declaration.
- If such a declaration is not provided or if judgement not possible, the measurements
