Destroyed diodes - help

Do i need to post the exact same photo hakzaw did? We have killed so many diodes during tests,so we know what are we talking about. Trial and error my friend
How about a photo of your setup? And a photo of your DMM. You must think this trough.
Diode requires somewhere between 2.2-3v and lest say 300mA to be at the safe side.
If you have a cheap dmm,expect a lot of error in the reading. Use a 1om resistor and measure the voltage across. I=U/R so 1mV=1mA. If a diode is working on 300mA and it is on a heat sink,there is no way for it to die unless you are doing something wrong.

Oh no, that's a breadboard connection.

Like I said in my post above, the connection to the diode must be permanent - solder it to the driver, don't use breadboards or alligator clips or whatever else is non-permanent.

That is the true problem IMHO, heatsinking is not an issue, never was, not with 60mA and not while the diode is in Aixiz module.
