Exactly. I've even seen 'party laser' products at dollar stores with moving diffraction gratings that project patterns on the walls, marketed like a kid's toy (and I think with a Class 2). Even worse, the EU norm for lasers has been amended for incoherent sources. Previously, LEDs had to fulfill certain maximal radiance requirements to not need a laser sticker. They raised the radiance limit for LEDs by a factor of 100 (so if it was coherent it's about a Class 3 now). I treat bright LEDs/flashlights like lasers now at close distance. Edit: (someone could classify a Class 4 diode laser array for heat treatment as an LED array now (given shitty M2) and avoid the laser norms altogether, despite the thing still being dangerous) |
