Cxb3590 4pcs,HLG-185H-C1400A 2pcs help ?

Hello,I have 4 cxb3590 72V and 2 Drivers HLG-185H-C1400A (200w).PC Ventirad Cooling,one for each COB.
I plan to use 2 cxb3590 series on each driver,in this way 1 cob have 100watts if I'm right.
A member cob user from an other forum say me than HIGH POWER CXB3590 turn they plants Hermie.
I never read this about COB ?
I read than COB light don't stress the plants like HPS if it's true I don't understand well why the plants turn hermie at high Watts COB ?
It say me to use 4 CXB3590 72V in One 200watts drivers HLG-185H-C1400A,each COB 50 watts,series paralel connect.
And order 4 others 36V COB like VERO29 3500K or CXB3070 very good COB when running at less than 50W,depend price.
Have good Vibes,thank's before for your help COB growers.BIG UP.
All help is Welcome it's my first COB grow.
Hope I read you soon,Friendly,Olsqueak.

I have not seen a hi-power light source create hermie's-I would say that if that is true then a bunch of HID growers would be a world of hurt. While it's certainly possible to run each of the arrays @ 100w it looks like you will get better growth(more uniform across your space) by using multiple light sources. Unless you are limited to Cree's by location, I would look at other chip manufacturers-much cheaper and more efficient.

some math 200w = 1.4a x 72v. two cobs will provide 200w. Each cob at 100w would need a larger heat sink to dissipate heat. you would also need to remove heat from row space. four cobs 400w two drivers is fine if that was your choice.

Hello,your help is welcome.
.I can win 12000 lumens Drive cxb3590 72v at 50watts.
4 cxb3590 72v in series parallel for one Hlg-185h-c1400a.
What's best quality price for COB 3500K ?
I want order 4pcs cxb3570 36v it's cheaper than cxb3590 aprox same lumens output at 50watts.
What's do you think about spectrum mix off blue,red,white led ?
Have good vibes,hope you understand my bad english.
Big Thanks,friendly,Olsqueak.

Additional red/blue are great light to use with cob white light. I would recommend Royal Blue 460nm and Deep Red 650nm. The Blue generates more energy and the red is the energy.
36v cxb3590 is the better choice I think.
Good choices.

Royal blue 460nm and deep red 650nm fabricants is Cree or others how much watts? need drivers and cooling system ?
How much power red and blue for 200watts cob 3500k ?
100watts cob have better penetration off light for grow more taller plants ?
Thanks for your help friendly Olsqueak.

On my 320W bars, I added 30W of XPE HE 660's that I run during flower. LPC-35-700 drivers runs each array. I use solderless chip sets from Rapidled and used thermal epoxy to mount them to the aluminum framework-they barely get warm. Produces a nice pink overtone to the room....reminds me of my blurple days.

Hello my friend can you give me link for buy xpe he 660's and lpc-35-700 driver ? I want looking this.
What's thermal epoxy for heat dissipation ?
Can you make a picture off your home made light when you have some times.
Mine is 4 active ventirad for PC processor with one cxb3590 72v 3500k in each ventirad,two HLG-185H-C1400A.
Perlaps I order one hlg 185h c700a and some cxb3070 36v 3500k for complete my setup.
Hlg 185h c700a for push 4 cxb3590 72v at 50watts.Better lumens output at 50watts 8000lux at 100w 13000lux

If you order a 185H-C700a//B driver you can connect all four of your cobs up to this driver and each cob will run at 50w each for 200w total power. 72v x .7a = 49.9w x 4 = 200w total power. That will allow your cobs to run more efficient and cooler and get more luminous power out of your cobs.
