Just learn a little bit about ohms law, that'll give you the formulas to do calculations on driver sizes. Cobs, boards and monos all use same formulas. Also study up on series and parallel circuits. Most of time we just build using simple series, in some of more complicated builds or larger builds use parallel or a (series/parallel) a combination circuit.
I haven't looked around for too many sites or anything on building. But growmau5 has a ton of vids on YouTube that should be able to walk you thru it. It's really simple once you get basics down.
Thanks Buck, I grew up installing stereos (Decks, door speakers, subs, amps, etc...) building boxes and doing huge installs for guys who compete in that stuff. So I have a basic grasp on Ohms law and parallel and series circuits... I'll refresh my memory and checkout those vids, as well as check all the components necessary for a build. I feel bad now cause I tried that light, and it just won't work for me in my current grow areas... I feel someone else could really use it... so I'm looking at building my own panel to fit my needs perfectly. Thanks for the advice! Ima get my learning hat on after work!
