! n% p* N' S: T* M" B& ]Decision: In principle apply the requirements given in IEC/EN 60825-1. However in order
& l6 S; f8 d- m( mto avoid expensive measurements, the luminaires provided with LEDs should be
treated in the following:
- If the light intensity is low, i.e. from a conventional LED for indication or signalling
purposes, the LED is most likely comparable with a laser of Class 1 according to
% m( _- e: N3 L3 R5 P3 Z/ A0 ]  a1 PIEC/EN 60825-1 and consequently there is no need measurements. During the
judgement the covers, optics and similar, which can be removed by hand, shall be
; a' Q& J; h) Y! g- s* `removed. In the TRF it is indicated that the light intensity has been judged to comply
with the limits given for Class 1 lasers in IEC/EN 60825-1 and no measurements are

) z3 Y0 T, d, U! z- In all other cases the luminaire manufacturer shall be asked to provide a declaration
based on relevant tests (e.g. from the LEDs manufacturer) showing that the radiation
  a6 U, r9 \( y: z1 K7 Jfrom the LED module will not exceed the values given in IEC/EN 60825-1 for Class 1
or1M lasers with or without optics. In the TRF it is noted that judgements have been
based on a manufacturer declaration.
- If such a declaration cannot be provided or if we are insecure on how to judge, the
measurements given in IEC/EN 60825-1 shall be performed. In the TRF it is indicated
that measurements have been performed. For luminaires containing light sources
) O, r: `# Y/ M1 i" hproviding radiation according to Class 2 lasers, the luminaire shall be treated as a laser
source according to IEC/EN 60825-1 and comply with the requirements given in that
standard.
