I know it´s a noob question but Im not sure about. Im trying to buy >100mw focusable torch to an chinese supplier that swears that his supplier says it´s over 100mw. The only fact I have is that it burns matches when on focus, so I would like to know what would be the minimum 532 burning black matches.

I have some 50 and 100mw and Im looking for 100 at least.

Thank you in advance!
 





I've heard of 30mW lasers burning... it all depends on how well you focus the laser. I used to have a 50mW green laser, at 1.5mm beam diameter it lit blackened matches no problem, within a second
 
A 5mw will if you expand the beam a lot then focus it.
You'll get bored quickly of lighting matches etc
