4 COB chips x 50W each = 200W. In practice each chip is getting a bit more because B series driver with capped dooming leads, plus driver loses = 225W from the wall.Hey bro, I have a couple questions I hope you can help out with. Just trying to get my head around the cob and I think I'm there.
If your using that driver to run 4, does that mean you are supplying 50w to each cob, but the output of the led is roughly 150w?
Second question, how many cobs would I need to flower out a 4x4 wall. Thinking of doing the side/back walls of my tent and make some sort of u shaped frame, that hangs vert and have cobs running down them.
I'm thinking you would want two rows per side?
Hope that makes sense
IF you were to use this same combination, you'd do fine with two on a 4x4. I sized mine for 2x3' of canopy per module and they're all but too strong.
