I think the confusion came from the different types of lasers, which I
did not provide any differentiation. I was speaking about non-focused
LEDs that are on display panels, not LEDs that are considered Class I
lasers.

I sure would love to hear that argument.
Just get a time machine and go back to the meeting of the IEC TC85
working group

LEDs are no longer considered Class I Lasers and the requirements for
them to be tested as such has been dropped. UL no longer treats them

IEC60825-1 uses units of energy, energy/unit area, power and
power/unit area (regardless of any special names
associated with them) rather than candela or lumens, which
are typical for simple LEDs. You'd need some formula to
convert

IEC-825 has incorporated LED's into the safety standard but, from
what I can tell, left a great deal of confusion.
I typically deal with the 5 - 10 mcd devices and haven't been
required to provide any IEC-825
