Last year I bought a new garden decoration laser. Yes... I've already got four of them, but this one stood out since it is labeled class 3R. Stronger than my current ones in class 2!?

Perfect opportunity to investigate the different laser classes. Where does 3R fit in compared with class 3A and 3B? Is this new one really stronger or is it just another mislabeled laser?

Even STRONGER Garden Laser?!? | Laser classes explained

Time to test my newest garden decoration laser. A more powerful class 3R unlike the others in class 2. Or is it? I will explain the different laser classes and test if it truly is stronger or yet another mislabeled laser.

It’s crazy how these are legal. They seem like they would be dangerous shining into some ones home

To be fair a few stray beams spread far apart and seen from far away from the laser are not problematic. If 40 mW is split into say 500 beams, each beam is 0.08 mW. Not a real issue. The issue is up close, if an animal or kid passes by close up and look into it while being hit by several or all beams. But the whole idea of having laser beams hitting a house, windows etc. is just inherently bad. Luckily it seems like these lasers are being replaced by LED projectors in Denmark. Way better idea :)
