Basically this light setup is for my flowering period. I will set up a veg tent/lighting setup in a smaller tent after I finish this tent. I'm researching Kelvin temp for the COBs right now and see that the 4000k gives more lumens/watt and PAR watts, and also raises the COB efficiency. So is...

I see you're using 4000K instead of 3500K, and if I'm comparing it to my calculations the 4000k has better lumens/w and PAR watts than the 3500k according to bggrass's calculator. So is 4000k better than a 3500k for this type of setup?

Lol holy shit I actually was preparing to build this setup albeit in a 700 ma - 1.4 a driver, never thought of going as high as 1750 ma. Do you have any regrets going with a bigger amperage driver? Should I do the same? From what I'm hearing, just dimming down one of thes bigger amperage...

Hey, was tinkering with the calculator you linked me and basically here is what I came up with. HLG-240H-C1400B (x3) CXB3590 DD 36V, 5000k (x12) HUSA Heat Sink 4.230” x 46” This setup according to the calculator will run the COBs at ~65% efficiency And according to the calculator it...

So Basically if I had 8 COBs in a heat sink, I'd have 80 heat watt to deal with right?

So what you're telling me is HLG 320-36b will be 95% efficient in regards to photons:heat ratio, if so how much grams can i expect per Watt? Would I be able to pull around 1.75g per 1 Watt? Edit: I do not want to run a parallel wiring setup. With the 4 HLG 120h-700b setup how much...

Would this setup generate a 65% efficacy? http://www.mouser.com/ProductDetail/Mean-Well/HLG-185H-C700B/?qs=%2fha2pyFaduiOPDwH1bzWDfG7gOsrIoSmXr8%252b0GewqKiMSNgDWJUSPA%3d%3d Citizen1212 CLU048-1212 80CRI 3500k (x8) 4.23" x 46" heatsinkusa Heat Sink...

Here is how I did my math. Basing off Growmau5 videos (he uses CXB3590s) Using Ohm's Law = (FV) x (i) 1212's running @ 700mA = 34.04FV x 0.7 = 23.828W With 6 COBs wouldn't it be 23.828W x 6 = 142.968W (~143W) And if I'm not misinterpreting him, Growmau5 said with a 700 mA driver setup...

As in I would have to rely on parallel wiring? And what I meant by 65% efficient is since a 700 mA/215V output Driver will run 6 COBs @ 65:35 (photons:heat ratio) and generate ~143W or am I doing the math incorrectly?

I'm confused since the Output Voltage and Amperage seem a bit off from what I'm used to seeing, So for the HLG-320-36B the output is 36V with a 8.9 A. Wouldn't the 36V only be enough to power 1 COB and wouldn't 8.9 A blow up my COB? Also would (4) HLG 120h-700b work for a 6 COB set-up at 65%...

Edit: I now see what you mean by ELG generating only 70% @ 120 VAC (I'm in the US)

Thanks for the info! If my first grow is successful I plan on upgrading space and getting more COBs, driver, and heatsink.

Hey guys, So after a good amount of research I have decided on this DIY COB setup that will generate 571.2W with a 65:35 (Photons:Heat Ratio). I am using a 4'x4'x7' iPyarmid Grow Tent and actually still have some questions on ventilation. But here is what I have in mind for my light setup (which...

Hey man, I just finished my setup for DIY COB! Thanks for not letting me buy Blurple lights :D Can you give me your opinion on what I plan on setting up: http://www.rollitup.org/t/first-time-grower-final-diy-cob-tent-setup-need-approval.925159/

That's actually a brilliant idea! Holy shit, yeah I'm going to tinker around with smaller drivers

Yeah at this point really trying to go with 16 CXB3590 (3500k,36v) @ 1.050 amp I've also been thinking about running 22 CXB3590 with 2 HLG-320h-C700b (428V, 700ma) but have no idea what type of heatsinks I could use for that set up

thanks! probably will get it from cobkits if the duty tax for import beats the +$9 per cob.
