yeah i know it was a vague question but i typed out a lil paragraph up higher and it just got skipped over so i just threw that back out there, lemme copy and paste from above so i'm just trying to imagine how much power i can ultimately run on this 10" by 36" heatsink. right now i have 200 W...

how close can you place the CXB3590s to each other?

so i'm just trying to imagine how much power i can ultimately run on this 10" by 36" heatsink. right now i have 200 W on it passively cooled with eight CXB3590s. I want to put 200W more on it for sure and know it could take that, but the question is how close can you place the CXB3590s to each...

oh well since i have the hlg-185h-c700 i will need to run the 72V to get proper efficiency and run 4 of them. but if i run 8 of the 36V it will be just as "bright" but just spread the lighting out? and be just as efficient? i was thinking that more cobs is better with the same amount of watts...

so i'm about to order stuff real soon, you talking about the cxb3590 at 36v or 72v, and you still mean to run them with the hlg-185h-c700?

yeah i need to make an order here soon, need to find someone with heatsinks though

what heat sinks do you all recommend to run some cxb3590's?? would be really nice to get something pre-drilled and save me a bunch of time :blsmoke:

yeah i know that cree are the "best" out there the hlg-185h-c700a but it seems like your saying to run 4 per driver

oh well maybe he didn't say that at all but i just got it from this chart https://www.rollitup.org/t/matching-drivers-and-cobs.883866/

ok gotcha, so pretty much 16 cobs and 800w for a 4x4 will make me happy? so you think it's the same for the Vero29? so you are trying to run them like i was running 4/that driver, yeah i'm sure that would be lit for sure. On a chart i saw Supra put up it made it seem like the vero29 and...

right now i'm running them with some Vero29 35K, was running two per driver then realstylez was tellin me i could run all four on one so that's what's going on now. I'm still trying to decide if i liked running them harder or softer, but they are pretty awesome either way. They are the A i...

what's good man, finally mad it over her to talk some real COB DIY!

niiiiiice thread here, looks kinda empty now but i have two hlg-185-c7's from what it looks like on here i should be running eight of the 3590 at 36v per driver?
