Hello, what is the minimum mW required for a green laser pointer to light matches with a magnifying glass?
 





Re: Burning barrier for green laser + magnifying g

A 50-75mW should do the trick with magnifying glass. However, you'd need safety goggles, as the dot would be to bright to make an estimate of the focal point. Good luck !
There are some cheap stuff on the internet that does >50mW regardless of the build quality.

I live in the United States. It is illegal to import anything > 5 mW into the US unless it is FDA approved.

Where can I buy a 50 mW green laser pointer that is FDA approved and under $200?

Otherwise, where can I buy a 50 mW green laser from a company that is located inside the United States?
