Seems like an excellent quality pair of safety eyewear. If it were just me using the laser, I would buy it, but as I stated above, I will be doing mini light shows for friends and family so I will be spending some money a few cheaper pairs. I will definitely be getting those once I save up enough though! I see those everywhere and they seem great.

You can't wear safety glasses during a light show though. You won't see anything!

Oh yeah huh? So would it be safe to look at the beams during a light show, not at the dot and not directly. Like standing to the side while looking?

Yah. Beams are perfectly safe to look at. The problem comes when the beams end in your retina:D

Hey Shuffy10,
Here is my take on your post, what is more important to you, burning things or making a cool laser light show using diffraction gratings and other optics? When I purchased my first laser, I thought about burning but decided on a lower powered laser to be safe with my first laser. I purchased a Dragon Lasers 445nm 200mw Aurora. I looked at the DL 1W Spartan but thought for my first laser I wanted to be safe and didn't want to take chances with a laser that could do me damage. I also purchased DL Safety glasses with the Aurora. I now have 3 lasers that can burn. I have a 1W 450nm and 2-405nm 500mw. After the novelty of burning a black CD case or a piece of black tape, I do not burn anything anymore for a lack of interest. However, when I started to photograph my lasers, I realized my 1W 450 laser is so bright, when used with other colored lasers it washes them out, and as pointed out in the above posts is VERY dangerous in the hands of a noob. My 405nm's can be used with other lasers in a "laser light show" because the beam is not bright. If you look at any of my posts of laser scenario set ups I have done and photographed, most of the lasers I use for them are between 5mw and 200mw. Even my 200mn 445nm Aurora is too bright to use with most of my other lasers. And most importantly lower powered lasers are MUCH safer than ones that burn. When I set up my lasers to photograph I will use my safety glasses. When I start to photograph I do not use them and feel safe, as I have been setting up many different scenarios but always realizing the risk, which is minimized with lower powered lasers. I see your budget is 240 dollars excluding goggles. For that amount of money, you could buy 3 lower powered different color lasers in the 50mw to 100mw range (check Offroads Group Buy for Laserbtb lasers in the Group Buy section), and get two diffraction gratings from N04H99's diffraction grating Group Buy (though it will be closing out in a few days I think). I can guarantee you can create pretty awesome and much safer laser light show buying from those group buys. So if you are willing to forsake your desire to burn things, you can do a laser light show that is in your budget that will certainly impress.

As far as using your lasers outdoors at night, to me that is a no no. I live about 20 miles from Newark Airport in NJ and there are always planes overhead in their landing descent . The only time I have used my lasers outdoors were in my fenced in back yard and keeping the beams in my yard, so the only people that can see them are people in their second floor looking out the windows. My avatar was taken outside after snow was melting and created fog, but as you can see the beams stayed in my fenced in area.

Good Luck!

Lasers are high profile and generally attention to them, especially in the news, is bad. When using your laser, ask yourself, "is this likely to draw unwanted attention or cause any problem?" if the answer is yes, maybe, or not sure, don't do it.
This 'Situational Awareness' will help the hobby/hobbyist survive - sort of 'Strategic Paranoia'. After all, nobody goes around letting go signal/distress flares into the sky for nothing. (Lasers are actually useful as rescue tools at the right time : HERE). But I am also amazed by the spectacular display of flares that are seen globally in harbours, marina bays and beaches on new years' eve at the stroke of midnight!:rolleyes:
