Advice on buying would be greatly appreciated! Third green laser, looking at 150mw

Thank you, all very informative. So unfocusable lasers generally can't light a match or pop balloons? Not even a 300 or 500mw?

Okay basically anything from 50-150mw should be focused if you want to burn, if its >150mw and is not focused you should be fine for burning, it just speeds up the process if you want something to light fast, like a match. Yes a 300mw can burn without focus, but it would burn better with focus.
