So I got a few Cree 3070s and an HLG-185H-C1400B driver, I went to test out my cobs and 2 of them popped. I have no idea why. I tested them individually, and as far as I understand, voltage doesn't matter as long as its Vf or exceeds Vf... no idea why. It's a constant 1400mA output. Just wasted $54 from my stupidity. Any help is appreciated before I pop some more.
