I acquired two cheap green laser pointers with AAA batteries. They are generic no name brand. One sticker says <100mw the other says <240mw. Sounds good, lets test a little. I am an absolute newb so I don't have a LPM. I do have balloons and matches.
First I tried both pointers on a red balloon, neither popped it from even directly on it. Next I made a black dot on the balloon and the 100mw pointer pooped it right away from 1 meter away. The 240mw pointer did not pop it at 1 meter.
I thought maybe the 240mw pointer had weaker batteries so I swapped the AAA's from in each pointer. The 100mw pointer still popped the red balloon with a black dot at 1 meter. The 240mw pointer still did not pop the balloon.
Neither pointer will light a wooden match at all. I waited 30 seconds before giving up. My question? Do the warning stickers mean anything or are they just for show? If you cannot trust them who can you trust?
