Good question. I have been hearing about this lately and have relied upon
the vendors to give me a heads up. Not all LEDs are involved and I am trying
to sort this out.
Shouldn't that read "coherent" rather than non-coherent. As was discussed
not to long ago the issue of laser light and focusing of the light can move
a laser from one class to the other.

Subject: LED Reqs under A11 to EN60950
Hello group!
I would like to hear how some of you are handling the requirement to
treat LED's as a laser device, as required by amendment 11 of EN 60950.
The information I have received is that all LED's that are sources
of non-coherent light will be classed as class 1 lasers. The equipment
would have to be labeled as a class 1 laser device, and list EN60825 as one
of the standard it complies to.
This really seems excessive for a simple LED used for, as an
example, power on indication and so forth.
Thanks in advance
