Well, the strange part is that LEDs are included in the European regulations. What happened is that they wanted to outlaw laser pointers to be abused by kids. So they reformulated the laser regulations. But, being politicians and lawyers, and not MDs, scientists and engineers, they came up with a definition that happened to include LEDs as well as laser diodes.In Europe you have laser class directives regarding LEDs, which you do not have in the US (strange but true).
According to these directives all LED lamps which are laser class 2 or higher has to have a warning sticker on the lamps. But if you have an LED with laser class 1 you do not need to have this sticker due to that the LED is safe.
If you look at the LED datasheets most of the LED suppliers have the laser class information printed.
Most professionals I know consider the current regulation ridiculous because of this -- it does not say anything about the danger of the device due to the inclusion of safe/less dangerous devices in the same class as truly dangerous ones.
