There are two problems with this statement:
1. UL does not apply in Europe. and
2. UL is NOT a law, it is a clever deception. A testing house set up themselves as a defacto safety standard and convinced everyone that it was a law. They get $5000 dollars if you so much as change a letter in the documentation and want to keep their mark. An exaggeration, but you get the point. It actually has a lot in common with M$ in that respect
That said the LEDs under consideration are crumby and beyond the capabilities of a simple experimenter to mount.
