Hey guys,
I just have a quick question. I just received my drivers with chinese cobs. My cxb3590's are en route. I just wanted to wire up my drivers with the cheap cobs to be sure everything worked. One of the cobs was kind of flashing...on for a second, off for two seconds, on for one second, off for two. The other cob worked as it was supposed to. I tried the other cob on both drivers and it worked fine. Which leads me to believe the single cob is fried or just shotty workmanship? I just want to make sure I'm not going to bugger up a CXB when they arrive. My driver specs are 25-40v, @ 1500ma. I'm only going to use 2 cxb3590, each ran with it's own driver.

The length of wire from my driver to cob is about 10 feet. Would this cause voltage drop to the point that the driver would struggle to keep it lit?

unlikely you will have voltage drop over 10ft, what gauge wire do you use?

The problem is that driver can only run 1 CXB3590 36v COB

looking for some input- some of these use 3070's and some use 3590's. I think cob is where its at for the future, and these are the companies Im looking at. Any input or comments welcome. I know diy is better price wise but atm I just want to pickup another complete light. All are similar in price. Im wondering what the main differences are between these.
I think any of these lights would work well. The shell looks the same in the go green and the johnson.

All these have similar outputs with 2-4 chips. So comparing the go green and the optics- both pull 200w. Same output but one has 2 chips and one has 4? Can someone explain that to me? My guess is that the optic runs them twice as hard, or that its related to voltage and amperage and other spec numbers which gets confusing to me. Or the same chip model comes with different ratings (for watts/amps/voltage)? But thats a guess with some very minimal led knowledge. Any other notable brands i missed? Key points im missing?
