If it were me I would put 4 50W COBs on a 3.5" X 40" and run an 80mm fan in the center. That will spread them out, use the heatsink efficiently and use the fan power efficiently. Having 2 heatsinks rather than 1 will also give you more adjustability for your canopy. That is just one way to do it there are so many configurations

Hi,

Could someone help me with a build for 2 cxb3590s? My goal is to product 100-150w worth of lighting. I am planning to run them on artic cpu coolers and need suggestions for power supply and other parts I would need.
Thanks!

been reading threads here over the past week and so impressed with all the knowledge to be absorbed. more than sold on making the switch from my 600w hps and 400w. been taking in as much as i can and taking notes but its clear ive only scraped the tip of the ice berg. intend to keep reading and learning but i am anxious to get my parts ordered and building/growing!! so being another noobie probably unworthy of this cache of free education ill have to bug you experts for an opinion.. i have two 4x4 tents right now running on a scrog.

i believe ive decided on this build that supra posted

@ 56.3%
(4) CXB3590 3500K CD 36V @ 1.4A (49W ea) $190
(1) HLG-185H-C1400 $65
196 dissipation W -> 85.7W heat ->
passive cooled heatsink 10284cm² -> 5.88" X 38" heatsink $72 (could split in 2 to improve uniformity/spread)
w/ 80 degree lenses

i initially planned on doing 2 of these and got a quote from jerry @ kingbright but have been wondering if i should go with a 3rd for my 4x4 space. additionally i also thought maybe mixing in some 3000k's or a different build if you had some sweet suggestions on a 3rd heatsink but maybe should just keep same setup. eventually in a month or 2 im going to make a 2nd identical light so i have it in both tents. with the heatsinks and quote from jerry for that build 2 would come to ~$722 .. $1084 to go ahead with 3. many many thanks!

400W of CXB3590 COB LED at 56% efficiency is going to do a respectable job in that space, about 600PPfd. An additional 200W would definitely put it in high intensity territory. Going to 800W would get you over 1200PPfd!

You could run the pair of CXBs on an HLG-185H-C1050A. That would give you about 85W/COB.

You can mix colors, 3000K CB 3500K CD and 4000K CD. It might even be beneficial. I would like to test each of those to see how much PPFD each will really put down

I would go with three of those builds for a 4x4, that sounds perfect. That is the exact setup that I want for my 4x4, should be great spacing and intensity and efficiency obviously. 21 PAR W/ft^2 and 3/4 of a cob per square foot. But thankfully 400w will do ok too so if you need to save up for the extra 200w, that will be fine. That's my plan pretty much.

Well I have a CXA3590 at 756watts day 1 of week 4 of flower. Six Thin Mint Cookies in a 4x4 tent and the some plants are 48" tall.

Great stuff! These under the 3500k chips? Are these chips being run at 50W, or?

I fucking CAN'T WAIT for my 4x50W=56% efficient CXB3590 @3500k modules to get here! They'll be here next month and I've never been soooooo excited for Christmas before in my whole life!

so as i thought what im gathering is... if i can afford to dump the money into the extra 200w , do it :P
Just remember Aladdin; 'ULTIMATE POWER! Eensy weensy growing space!

Now we ALL know why the Genie went back in the bottle so willingly!

That would also be dimmable, correct?

That is the cxbs I have. Thanks Supra. Your threads brought me in this direction.
No prob man, it looks like you have the 36V version of the COBs, in that case you would use separate drivers. A pair of $40 HLN-80H-36A would give you 100W to each COB with internal dimmers. You could use a pair of $12 generic 1.4A drivers and get 50W per COB with no dimming.

Hey Supra, once again thanks a billion for all your posts and inspiration on here! Currently building my second CXB3590 unit. This time with 6500k. I'm going to throw down my 2 cents on a few things I've seen posted around here, whether you want it or not :P

Pot size: IMO this is a huge factor in organic gardening. Most ppl I know recommend 20 gal minimum. Then again, they're growing big trees. The important thing is not to over or underwater and the 20 gal gives you more forgiveness in this. However you need to be careful of aeration in these bigger pots. I would fluff up and mix between runs to re-introduce lots of oxygen down in there.

Vaporizers: I use the Silver Surfer and have been for 5 years. I love it for efficiency, flavor, and durability. The flavor is great on the first few hits but then fades quickly. Vaporizing takes a while to get used, and gets better and better as your longs clear out all the old ash and tar built up. The Extreme Q is an excellent value model as well.

Thanks a lot Supra. Is it alright start a conversation if I need any more advice?
 
I come up with 360 PPFD:

3.75' X 3.75' = 14 sq ft
50W X 4 = 200W * 56.3% efficiency = 112.6 PAR W
112.6 PAR W * .9 lens/wall reflector losses = 101.34 PAR W
101.34 / 14 sq ft = 7.23 PAR W/ sq ft
7.24 + 4.65 umol/s/PAR W * 10.7 (sq meter conversion) = 360 PPFD averaged

The way I like to find the best spacing quickly is to make a mockup. You can put a slight bias to ward the walls because the center benefits from the overlap
@SupraSPL hey just trying to work my specs out using this formal and just a couple of questions

what or how is the .9/wall reflectors worked out...I'm not using lens but have reflective walls, is the .9 just a average or something?

where does the 4.65 umol/s/PAR W come from?

and how has the 10.7 (sq meter conversion) been worked out? to me this is saying its the sq meter conversion of 14 sq ft? but that can't be right because 14sq ft to sq meters is 1.3 sq meters

also 7.24 + 4.65 x 10.7 = 56.95

Sorry man not trying give ya any shit just trying to work this stuff out for myself;)

Are these the right drivers Supra? Would the generic drivers be any easier to assemble than the meanwells? Thanks again. Sorry for all the questions.
