Oh, sorry, my calculations were for 6 COBs, 048-1212.
So for 5 COBs... 2.8/5=0.56A ---> around 18W each.

If i brought the citizens CLU048 1212's would they run more efficient with that driver?

Yea, better buy 1212 gen 6. They are 50 pounds I think. You can go with that driver if you don't have money for better.

Yeah i think i will go with the 1212's, i brought that driver on someone's misleading info lol so i want to make use of it really. I will have 7 1212 cobs when i get these, what's the max amount i can run on that driver?

Each COB you add, you'll divide amperage.
2.8/7=0.4A each.



Last row...
And that, my buddy, that's pretty efficient light at 181 lm/W!!

But... better ask MW or someone one thing: COBs are running at 32V... driver is rated at 36V +/- 5%, which is 2V. So minimum 34V? Look around if someone is using this driver and those COBs... Better safe then sorry.

this is exactly what I have done in the past. It would cool better with the cob an inch or so towards the middle. More immediate surface area for the heat to be absorbed and to help dissipate. You should try and clean up the paste a little better too as it will attract all sorts of dust and turn pretty nasty.

Ok thanks I'm just trying figure out how to mount the heat sink that's the problem.

I can put both in the middle but I think they be to close and man I'm sorry I just don't have funds at time or I'd went the professional way and let u built it for me
