Actual Power of a 30/50mW

[savingbirds]

I've seen many slightly larger green lasers from focalprice and tmart that run on 2 AA batteries, which are a lot easier to find that many others (including leeching AAA's from remotes).
Ex:50mW 532nm Super Bright Flashlight Style Green Laser Pointer (2*AA) - Tmart.com

Did anyone buy these kinds of lasers and actually tested the output power?

My experience with '50mW' greens in that price range is that they'll measure anywhere from 10-30mW of actual green on average. I've gotten ONE that was overspec.. when I bought a batch of them before (not these, but an 18650 laser in the same price range)but I think they screwed up and got product mixed up, since the actual module in the overspec one was different from all the rest..
