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.
All LEDs were previously subject to approval for a CE Mark, but
non-focused display types were not required to be by UL. The Europeans
have adopted UL viewpoint on these types of LEDs only. Non-focused
display LEDs are being dropped from the program, the others continue to
require approval by both the Europeans and UL.
Sorry about any confusion.

Subject: Re: LED's and laser safety?
Gary, I was recently in conversation with UL about LEDs whereas I am
now being told that UL has convinced the European counterparts that
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
that way in their CB Reports.

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 conformity proof for the Western
European test house. We may be jumping up to about 60 mcd and
non-focused devices and I don't know where the standard starts to
become concerned. I hate to buy the standard if it doesn't provide any
clarity for these types of parts.
Could you folks clue me in?
