Ok, I would love to get some help to make a driver to put out 380mA of current. I made a driver to run a LPC-815 diode that operated at 270mA but now I'd like to use an LPC-826 and I've read that they run at a higher current of about 380mA. What can I do to modify the circuit I have used to get the new desired output current? Here's my circuit on this "instructable":

How to build a laser (general guide)

My LPC-815 worked with this build using two trustfire 14500's for quite some time until it just recently quit. (I'm not exactly sure why) but, I wanted to replace it with something similar but a tad different and I found that in the LPC-826. So, if I could get some pointers in the right direction on how to modify this circuit to get it to produce 380mA I'd be extremely grateful.

Thanks so much guys.

Thank you. Of course there never really is a way to do something other than going through and actually knowing the theory. Thanks for the link!
