I don't know. It was two of DTR's 12mm modules. You may have to speak to Jordan to find out. As I just buy the modules with the driver and wire them up.
I'm unsure about the current but both are the same. DTR sells them with x-drives. With diodes like that, you do sometimes see inefficient ones. I could just have a lower power diode.
I reckon it is something to do with efficiency. Or a problem with the driver.
It could also be a failed lpm measurement, so I will have to determine if it is that.
