Richard,
I don't believe that the standard applies to LED indicators instead
it is for
'LED-based optics' used in fiber optic
We have a product using a focused high power led array which we had tested
and was determined as Class 2 and so mark the equipment such.
There are a number of high power leds on the market for use as indicators in
areas of high ambient light, i.e. public display boards.
When viewed from close

maze.
Thanks

Rick,
We manufacture light sources that are used to inject a known amount of
light into a fiber optic cable under test. Our high cost models use lasers
and our low cost models use LED's. When it comes to these light sources, we
do indeed consider EN 60825-1 for both the laser and LED models.
