I bought a 30mw Aixiz green dpss awhile back. There is a label on it that says 532-30-AC so I assumed I got what I ordered. But as time went on I looked on the Aixiz website and noticed that the picture of their 30mw module doesn't look like mine. More time goes on and I am browsing ebay and notice that both Aixiz and ajiii/dave sell a 50mw green dpss that looks exactly like mine. Could it be that I got a 50mw laser? No, couldn't be... the sticker says 30. So I assumed that maybe I received a detuned 50mw that really puts out 30mw. Well, I received a laser meter today and sure enough, the thing is putting out 50mw. Free power rules. I had wondered why this thing is so freaking bright and now I know.
