hey guys, just got these in:

funny story-- I attempted to turn amperage all the way down and connected it to an old 10x cree xpg "cob" I bought a year and a half ago. Good thing was, it was already damaged goods - 1 of the 10 LEDs was out. Anyway, it flickered a bit, then went dark and I smelled that 'something burned' smell. I then tested on a newer VANQ full spectrum phosphor cob - lit up nice and bright and I noticed on my KillAWatt 130W. Quickly turned the little screw the other direction until it went down to 50W. Only then did I notice that the driver is actually marked 150W on the PCB. Long story short, i think these will actually do 3.5A at only $15 a pop. Not bad, and I don't feel too bad for the old XPGs i burned up in the process.
I don't yet have a Vero29 to test with, so I'm not sure how high vF will go.
