Yes I do and I like using the 5 hole wagos for that part
Also i couldnt find the wagos but i got the 5 hole push ins from home depot

Would I be able to use 5 of the 3590's with one driver? Thx a lot RS for such an awesome tutorial.

Yes but you'll need the 36v and you'd use a HLG-185H-C1050A that has a built in manual dimmer. Why 5 on 1 driver? What are you trying to do with the light?I need more info so I can help you better.

Btw I don't know which volt you are using but if it's 72v you can add 1 more cob to that panel.

The HLG-185H-C700A can do 8 36V or 4 72V CXB3590
First off nice nugs. They look dense as shit!
2nd i think you have my question confused with the guy above me.
Yeah i was gonna put 4 on the panel but i was advised against it. Plus im about to rig the other cob up for the mothers.
So when they are ran at 700ma what watts are they going at. Any idea what the lumen output is with only the 3 3590's on it.
You're right, the C700 can do it but you're limited to 25W for each 36V cob.
Great for efficency, not so great for intensity.

No I just noticed you are running a 700ma and only 3 cobs if they are 72v you need one more to get the most out off the driver.
I just built a light using 5 CXB3590s 72 Volt version and and running all five off of one Meanwell HLG-185H-C500A. The A version has a recessed screw covered by a rubber cap, that lets you adjust the amps with a screwdriver.
You can buy the wagos off Ebay or Amazon. They better than the push in versions available at home depot because when you close the lever, the wagos really clamp down hard and when you want to change things, just flipping the lever up releases the wire completely.
Nice looking plants Real. Funny how you show everyone how to make a really good light and you have the plants to prove it, but some are reluctant to take the plunge.
I have CXA and CXB3590 72 Volt COBs running on drivers putting out 1.2 amps, 1.05 amps and 0.5 amps. They all quite a bit of intensity.
But your are right, it is a trade off between amount of light and efficiency. But it is not linear. As you increase the amount of amps, you do not increase the intensity as much, since the efficiency suffers and more and more of the extra energy goes into making heat instead of more light.
Realstyles,
Thank you so much for all the time you spend teaching others. I've read your threads on various forums...
I am finally ready to make some lights. I am mechanically inclined but suffer greatly when it comes to electronics. I have tried to learn what I can before asking questions. Don't wanna be a nuisance, but probably will be with the following questions.
Due to heat and electricity consumption issues, I have areas that I wish to use COB LED's.
Long time grower (many decades), outdoors and traditional HPS/MH...
1. I see a lot of references to using one meanwell driver for 4-5 CXB3590's but never 6. I have several areas that I would like to do a 2x3 array of CXB3590's.
Is there a driver available that would work for 6? My plan is to order a large lot of 3.5k CXB3590's. What would you use? 36v or 72v? Which driver? Should I get a driver with adjustable current? Which current should I drive these at? (I do want higher efficiencies, but need light intensity also) Which bin? (I will contact Jerry and tell him you sent me).
I think I can figure out heatsinks, fans, and all construction.
2. I also have a veg area that is about 30" x 40". My plan was to also use 6 COB's for this space. Obviously, don't need the same light intensity. Which COB's would you use and what light spectrum? I was thinking it might be easier to stick with the CXB3590's and dim them, but since I would need a different spectrum (really concerned about limiting stretch), should I use 3070's or Vero's? Also, a matching driver for this set up.
I would be eternally grateful for any assistance. Figuring out this stuff makes me think I'm getting stupid in my old age.
Cheers

I run HLG240H-C1400A For 5x 100w/36v COBs ran at 50w a pc with half current .Thus of the max rated current of the COB chip 3800(Ma) . Miliamps decides on power gave to each chip . Followed by output volts of the driver
HLG240H-C1750A for example is a 143v output this means I can 4x 36v COBs 4x36 = 144v volts . So output of the driver fits the requirements for the 4 x 36v . They will be ran at 1750 Miliamps this means each chip in a series circuit gets 62.4 watts a chip. Thus due to the driver puts out 250w
