Green laser with 2 power modes?

I'm looking for a handheld green laser that can produce 5mW and perhaps with a switch or dial, produce up to 30mW or even 50mW.

I found one online here that has dual power 5mW / 50mW:

High Powered Laser Pointers | SKYtech Lasers

But this company seems to be out of business!

Any help is appreciated.
