need help with 405nm build

[goophy]

I have a 405nm 200mw diode and not sure what driver I should use. I would like to keep it a while so I would like to find the write driver. And also what batteries and how many volts should I run. I could really use some advice, thanks.

Well, it all depends on the batteries, the first step is to figure what would fit into the host.

Yes we need more information. Since you want to use batteries, that implies portability. The host you choose to use will determine what your battery options are. And your battery selection will determine what driver you need.
