My question I guess stems from what has been seen of the 8x diodes requiring more voltage at higher mA's. Does a test load for accurate mA setting need to be made? Should more voltage drop diodes be attached?
If the LD have a bigger FV, just add a diode in serie of the others in the test load
6 diodes = 4,2 / 4,5 V
7 diodes = 4,9 / 5,2 V
Guys, don't forget that with the higher current going through the test load diodes, the more voltage they use (like with the laser diode).
