    A lot of the lazers from non reputable brands have are more powerful than rated, I think it was styropyro that has videos of it. But also a few sites sell 1w lasers and also it’s easy to make as well.

      Yeah, I certainly wasn’t saying these would be hard to get. And yeah, a lot of cheap laser pointers are also dangerous. What I’m saying is basically, “Hey, this is potentially dangerous, read up on this before you reach for your credit card.”

      And there’s lots where they use frequency doubling to make the laser light while having very poor filtering. Meaning that not only is the visible part of the light very dangerous, but the invisible light (which may have unpredictable patterns) can be even higher wattage and far more dangerous because you don’t even know its there.
