This driver outputs 71-143 volts 200.2 watts 1.4 amps ( it will run your chips a little harder than 50% but theybwill still be very cold to the touch and very efficient

Oh man i hope you can too, i have made the same mistake though so i know what you are going through. I wish they told you what drivers to buy when purchasing the damn led's haha

Check out "growmau5" on youtube. He does a lot of tutorials on led building, hes a little extreme though

Order your driver's from jameco.com electronics store, and your chips from digikey.com and order your heatsinks from heatsinkusa.com

And personally, i dont like cree. They tend to be difficult to find drivers for, and i feel like they dont work as well for flowering. The new decor series vero29 has a cri of 97 and the trich development of my buds is insane. But thats just my preference haha, all leds are good though, evwn the shitty chinese ones make decent grow lights

Ive bought everything already and have built almost all of it. Now i have to return the drivers and get different ones

Yes. 5.2A / 3 = 1733mA

Could you post a picture of how you have it all wired?

I wanna make sure its done safely, these things can be a real fire hazard if wired or powerd wrong

Yes i can

It looks good drom what i can see, just get the different drivers and you'll be in business. Just remeber that when you power them up, you can only run the chips for a few seconds without a heatsink attached or else they will overheat

Ok cool thanks a bunch

So i can hook them up in parallel and they work. What do you think about hooking them up in parallel?

If they are working in parallel then its a fluke, and i would be very cautious about powering them even for a small amount of time with those drivers. And if you do a little more research you will see that wiring leds in parallel usually isnt a hood idea to begin with because each chip ends up getting a different amount of voltage

Ive been reading up on it and its pushing 36 volts to each cob and the total amps (5.2amps) will be divided among the cob lights. The only problem they say to look out for is thermal runaway. Why do you say it is a fluke?
