Hello fellow diy'ers
I'm researching COB's for some time now and it looks like every build is about the same ... cobs run in series with a few meanwell drivers .
My question is " is that necessary ? is there some science behind it? a paralel run would be less efficient?"
I'm not a sparky , but I would rather have a cob array all paralel wired , meanwell makes 36v @ 16.7A ..600w driver
HLG-600H-36A , that will drive as many 36v cobs I want and if one dies there's no drama .the others pick up the slack .
On the other hand , picking up the right CC driver is a PITA ... you're stuck with whatever array you built , can't add any more without adding drivers or if one cob burns the whole thing is stuck till you replace the cob .
Please illuminate me
