Hi guys, new to the forum.
So I bought a quite cheap 300mW 808nm diode off of ebay rated at 1.8V 350mA (max 400mA) and tried running it with a variable voltage/current module I got from Amazon. I tested the module beforehand for proper functionality and of course set up the current output using my DVM. The module was powered by two 18650 batteries in series giving a voltage of about 8.4V when fully charged. Once all the connections were made and the diode powered up it didn't really do what it was supposed to do, i.e. start burning.
:thinking: I really need some help here because I have no idea what and if I'm doing something wrong, or if it's the diode to blame. I would greatly appreciate any help whatsoever.
