[Help] 50mW Green Laser Pointer

Okay.
Sorry but, it sounds like your "50mW" is more like 20-30mW.
You can try to pot-mod it, but you really do run an extremely high risk of permanently ruining your laser. :yabbmad:

People on the forums are saying that these green's are usually close to 50mW:

And, if you are going to get a laser that is actually 50mW, you really should get some safety goggles so you don't permanently blind yourself. :cryyy:

oh my god, but i buy an 50mW laser from a serious shoping website...why to give me an 20-30mW laser? but on my laser say: MaxOutput:>50mW ...omg i will call the company who sell my the laser

Well. I think you should be fair with them. they may have been sold the item as a 50mW laser, and so it is not their fault (possibly).

Simply tell them you are not satisfied, and that you want your money back (of course, you have to send the laser back to them).
