LOL, wondering how much laser power they are shooting on the faces of the singers ..... it does not look so safe, for them

 

[anselm]

It certainly is totally unsafe for my poor ears and mental sanity!:crackup:

Jokes aside, it's hard to tell from a video if it was safe or not.
Crowd scanning can be done safely, if the scanning speed is fast enough and
the power atenuated, remember haze can make even low poweed beams VERY visible.
But I somehow doubt the necessary measurements were taken in his case.:thinking:

I wonder, are there laser safety contact lenses?
If anyone had such a thing, I'd bet it would be the japanese.

I agree....
Unless they have Safety Goggle Contact Lenses...


EDIT

@ anselm.... looks like we had the same thought...LOL

Hard to say ..... i also thought about that ..... at 2.14 time, the reflex of the eyes are a bit strange, so it can be (or, at least, i hope it's so )

 

[jakeGT]

What powers are safe for crowd scanning? Like if you go to the club and their scanning the crowd, if you take a direct shot to the eye with a big laser fan, how's that safe?

 

[Antoniio]

Leaving aside the musical quality and musical likes (really, is a crap lol), I don't believe that we can know with totally assurance if the practice they are doing in the video is dangerous or not. But at first appearance, really looks dangerous.

Seems paradoxical that in a technologically advanced country like Japan, show stuff like this. I'm sure that they know laser dangers.

If we blind them, will they go away? :wtf:

Naah ..... more like "Hey, if we blind them, they cannot find the door for run away, and must stay and hear all the show" ..... :eg: :eg: :eg:

(j/k, ofcourse )



@ JakeGT, it depend both from the power of the beam and the speed of the scan ..... it's hard to say if it's safe, only from the video.

Thanks, I was wondering though, Like if i went to a club and they were scanning, and visibly hitting peoples faces, if I asked them the power/speeds and what not, how to tell if they are blinding me, or if it's okay?

Easy, you can do a simple test. When the ray approaches near your eyes, look fixedly the ray, if a few seconds later you see nothing, yes, the laser was dangerous and you've gone blind :eg: LOL

Easy, not true?

Jokes xdd

They SHOULDbe able to tell you that information.

However, that doesn't mean that they can tell you

Wouldn't that be something that they would HAVE to tell me? If the lasers shining in my eye balls were harmful or not?

 

[HIMNL9]

The problem is, probably, that most of the times, they don't know this ..... i mean, in some places, they may have a light technician that knows these things and take care of them, but the most part of the times, usually peoples that organize shows don't have those machines in property, and use external companies that mount and maintain the projectors and other lights for them ..... if you get one of them, maybe he know and can say you what you ask, but show organizers, is difficult that know those informations, they only can say you "hey, we called a company especially for this, so this must be safe, ask them for the info", or similar .....

 

[anselm]

Yeah they should, but to have a laser safety technician come and do all the measurements and calculations doesn't come cheap,
so I suppose MOST of the typical club/disco shows are NOT certified safe.
