Meeting:
! |, o6 r' j0 ^8 ADecision confirmed at CTL 42nd meeting
Question: How to handle LEDs used in luminaires due to possible harmful radiation.
Decision: 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
$ X$ @7 u4 D+ o3 I6 ntreated in the following:
- b* ^' S5 F7 Q; N- 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
, A& o. R/ D$ {9 S4 zIEC/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

: Z9 f- P( W% h8 h: v, e- 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
from 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
0 ~6 q, j. i, ^9 Q6 c5 Zmeasurements 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

Information about the action taken in relation to the LED radiation should be given in the
square “Summary of testing” on page 2 of the relevant TRF.
