Just to clarify, by module you mean that the diode attached to the driver, correct?

First off,

Look at the driver, does it have a pot or no?
If it doesn't have a pot, what are the resistors labeled as?

IIRC the voltage drop on rkcstr drivers is 2.25v
Your going to need at least 7.25V to power it, and the rkcstr driver has a maximum voltage in of 12v.

Okay I think it's set to 390ma just checking old pms about the order. I'll check if it has a pot when I get home.. Just want to build a labby with it.. What's the highest ma I can safely run an lpc-815 at? With good heatsinking..

we use to run them at 400-420mA normally, but even at that it will die eventually......

How do you find a voltage drop in a laser?
