Interesting. I think thats a single lazer, with a reflector or refractor lens over the top of it, which is why the lazer lines all have the same origination point. Nice effect though, thats for damned sure. Also, I am confused by the video title. I was under the impression that the arctic pro lazer was kind of dangerous to use in any format, without the application of safety eye wear, but no one in that video appears to be wearing any.

Of course, it might not have actually been one of the lazer units specified in the video title.

I thought it was dangerous also, at one point someone says "don't let it hit your eyes".
Still looks cool though

It's two lasers, 445nm blue, and a 532nm green. Definitely need to use laser shades with lasers like these, as they can cause severe damage to the eyes fairly easily. Even the reflection off a wall can cause damage to humans and also pets in the area, obviously these guys didn't heed the warning. It can also leave burn in's on a camera sensor.. In this case the beam is divided, or spread but still has enough intensity to cause permanent damage.

Sorry didn't mean to sound like the scolding parent, I've seen much worse on youtube where people have shined these class 4 lasers at cars on the highways and things like that. Even people lighting cigarettes in their mouths with no eye protection. I do have some of these class 4 lasers but I find myself not really using them that much because they are fairly dangerous, and have to be super cautious with them. Not to mention they attract so much attention, including cops. They do make a great survival tool, for signaling, starting fires, and desperate last line of defense.

No no dude I agree with you totally, people are stupid and If someone came on and said "Thanks dude I tried it now Iam blind in one eye" I would feel really bad

You are such a socially responsible monkey! I totally understand your point there, but I would say that darwinian action, to a certain extent will claim morons despite your warning, the warning on the side of the lazer, the warning on the box, and on the instruction manual...

But still. Good on ya boymonkey74!

Yes an eye injury can be pretty devastating. I've read some accounts of accidents on a laser forum and it's pretty sad. The thing about the 445nm blue is that the eye doesn't perceive it that well so it's deceiving how much light is coming out. For example a 100mW green will look just as bright to the human eye as a 1000mW blue, but obviously the blue will cause much more damage, although even 5mW can be harmful. Still lasers can be very fun to use, just have to be careful and understand laser safety.
