I just tested mine set @ 420 mA with a flexdrive and it outputs 250-255 mW
and 420 mA is a safe current if you use your lasers <30 seconds each time
Ditto, this is what I run mine at [except I use a rckstr driver and 7.2V (2XCR123s)]but as has been said, a heat sink and duty cycle are a must if you want it to last :beer:
