Recommended Operating Current (AC adapter)

[LaserJez]

Hey, I am new to lasers.
I just recently bought 3x 5mW lasers modules from DealExtreme (link below)

and i am wondering what is the suitable operating current for the laser. I have drawn up an image of what i was thinking of doing. (attached file)

Is it possible to directly connect an AC adapter with an output of 4V directly to the laser?

And suggestions will be truly grateful

yep that will work fine a great starter project i might add

note that module has a driver in it so you'll be fine oh yea 3.5 to 5 vdc should be fine
