All this COB Driver stuff is like a complex game of design and mathematics. Another option that I am looking at is running 3 Vero 29's in series with an HLG-240H-C2100A...

Here is the one I just built. Some of the plants they are over.

Right now I have some single 3590's on their own HLG-120H-C1400A's that work great. I also have two of the 72v 3590's in series being driven by an HLG-185h-c1400a. The 5000k ones are 77v though, so that threw a monkey wrench into it. I guess I am just going to have to decide if it is worth...

So your vote would be the 240 with them in series instead of driving them individually with the LPC?

So which of the proposed scenarios I laid out above would you suggest in regards to powering the 3590s?

Did you have a particular model you saw that would work with the 77v 3590's? All the LPFD ones I am seeing on MW's site only go up to 54v.

Well, I am looking at it like this in regards to the 240: Pros: Less equipment/hardware. I can run two LED's off 1 Driver Adjustable from 700ma-1400ma which would allow me to dial it down to the 1.2a I wanted to run them at 94% Efficient Cons: If one...

I guess if I wanted to not wire them in series, and run one power supply to each, I could use 2 LPC-100-1050's and run them at 1050ma instead of the 1200ma I wanted to... http://www.meanwell.com/webapp/product/search.aspx?prod=lpc-100

Correct me if I am wrong, but my understanding of you response is that either could be used, but they will react differently, correct? If I use two CXA3590's with the 240, if one blows closed so current still goes through it, you are saying the one remaining LED won't draw enough voltage, so...

Alright, I am sure this has been answered before, but I can not find the answer anywhere, including from Cree. So here it is. I want to run 2 Cree CXA3590's in series with 1 driver. My question is, does anyone know the Min-Max Voltage range of these things? I know they have a forward voltage...

Thanks guys/gals. I would love to transition to weed, but it's not legal where I live and I am too purdy to go to jail...so it wont be happening any time soon.

Just wanted to introduce myself. Back in September I completed my 90sqft grow room so I could give hydro/aeroponics a try. I have been using some Hydrogrow 336x's which have worked great, but I am considering selling them and moving over to COB's. I have been blown away though as the amount...
