I'm not familiar with the company, but assuming their advertised specs are correct...

You will need laser goggles. Any laser over 5mW can harm your eyes instantly

Any laser is potentially dangerous. Even 1mW lasers can harm your eyes

Properly focused, the laser will probably pop balloons.

Please search on the Forums for information, there's piles and piles of stuff on here

The only way you will know if the specs are correct is my measuring everything yourself... or sending it to a fellow member here at LPF to do it for you. You/your chosen member will need a LPM.

It is not safe to use indoors due to the large amount of reflective surfaces commonly found indoors. The laser is not dangerous for beam or dot viewing purposes, ie outside at night star-pointing is not dangerous, you do not need laser goggles for that purpose. However, pointing a laser at any aircraft is illegal in the US so be careful

For your future laser purchases, go with lazerer or laserbtb.

50mw 532 is not good for astronomy because it destroys your nightvision, but yes you can point it at stars. The beam of a 50mw green is very visible at night.

Also, I recommend using safety goggles if you are going to use it indoors.

It makes your pupils contract from the brightness of the beam, there-by ruining your ability to see well in the dark, where your pupils need to be as far open as possible to gather as much available light possible. In short, tight or constricted pupils = poor to no vision in the dark, (at least till your pupils open up again). This can take anywhere from a couple minutes to 5 minutes or longer, depending on your age, natural vision, whether or not your taking certain Medications, Etc. There are a lot of extenuating circumstances.................. Hope this helps, if not, PM me & I'll try to explain it better.

to correct hwang, you can use ANY laser indoors as long as you have the proper safety equipment, i.e. glasses, beam stop, etc.... you need glasses no matter what and if you go to the yellow link in my signature you can find glasses from $10-$500. pick which fit your laser and go from there. i recommend buying the most expensive ones you can and the eagle pair are what i recommend as a minimum standard although the uvex will do if you cant shell out the $50 right now

yes, you could use a 60W Co2 laser indoors but you'd need one heck of a beam stop and realllllllllllllly good glasses
