I have 4 total laser pointers. 2 red ones a green and a blue one.. I used the green one to make seagulls go nuts XD it's funny watching them try catch and eat the dot. The blue one will light a match quite easily,and pop balloons.
green>=50mW (can be more powerful but don't want to burn out diode)
blue >=100mW depending on input supply and focus range
