I purchased this "50mW" laser pointer off of ebay.

(just stick an "http" in there, it wouldn't let me post the link, though it's clearly not spam)

It says 50mW, but I assumed it would be less than that when I purchased it, since I only paid about $30 for it. I got it in the mail yesterday, and played around with it a little bit. Anyone know anything at all about this seller or this item? It came from Hong Kong. I haven't tested too much, but at night outside I could clearly see the beam and a bright dot, and in my lit room I could just see the really bright green dot. However, after a few seconds, it fades to be slightly less bright. Anyone know what the actual power of this might be, or what might be some good (cheap) ways to test it?

My first laser, by the way. At least since I was a little kid and had some red keychain lasers. And my first post here.

It's probably a little closer to 30mW , see if it can cut a bit of electrical tape though, 50mW should just manage too .

Okay, do I need to hold it over one spot for a while or something? Not really sure how to go about trying that. Just place the tape on a hard surface and aim the laser at a steady spot?

All right, I'll give it a shot when I get home. I'm actually sitting in my comp sci class right now....

But yeah, my laser is just a pen style pointer so it doesn't look nearly as large and scary as that one....but I'll give it a shot.

[smiley=smiley_up.gif]Now THAT is some serious green power. :D

Anyway, if your "50mW" green is about 30mW actually, it should, not cut, but but at least leave a small marking in it. My old "10mW" green from DX is dead now, but when it was alive it could leave a marking in electrical tape. It must have been lots overpowered, tho.

Welcome to the forums BTW .

You should use a piece of tape to hold the button on the laser down .
I prefer using a clothes pin. It holds it level and even, and wont leave residue.

You said "the dot lights up your whole room", if that thing is 30mW or up, GET GOGGLES! You're not really supposed to look at a dot from <20'. :-/
