I am enjoying following all of this led information
Personally I am not 100% sold that cob is it
Look at what Greengenes is doing with the AT600. Haven't seen a cob produce more impressive visual results yet
I think there still may need to be more research and testing to find the "secret sauce" spectrum if one is to save electricity while still delivering the goods

Look at what greengenes is using to try and outperform the Apachetech gear!
 
Will this work for a 2 x 2 tent? Would a 3000k + 5000k be suffucient for flowering in a 2 x 2 tent? Would i be better off using a 250w hps? I work long days and run errands like crazy in the evening. I don't have the time to do hours of research. Hoping all the pro's out there could give me a yay or nay on this.

Are all of the following compatible?? Will 2 of these units in a 2 x 2 space be sufficient or overkill?

You can't really go wrong with hps since it's old and proven technology.

The crees aren't compatible with the driver from that "high power led + heatsink driver combo"
The led driver puts out 3A and the max amp a 3070 takes is 2.8A or you risk end up frying it.
The 3590 isn't compatible with it either and it's likely a shit driver anyway.

Besides that the "100w high power led" is either not 100 watt or it certainly does not put out the lumen the description says it will put out.
 
Bonjour
And this seller do not talk about the BIN of the cob...so i believe that he sell only the lower BIN cob.
I would not buy from them if i was you.
The best BIN for 3590 is CD and just under there's CB and 4 X cxB (not cxa) 3590 36V (cause there's 72V) will fit on a hlg-185-1400.
Have a great day★
 
I'm looking to upgrade from my closet to a grow tent(4x4). This is my second grow and I'm just using 2 68 watt CFL's. I know isn't much but was a test grow and I enjoy growing. Really looking into getting a higher end LED light, been researching them and idk what I'm looking for. It's just a big run around. I'm not into a DIY yet. Just would like some input and suggestions on what to look for and a good company. Thanks

What's your budget and where are you located?

Around 2k but probably 1500ish after the tent,inline, etc and Ohio

Great, you're in the US, so shipping won't be an issue.
For LED light panels, Apache Tech, and Area 51, are considered the best.
For COB light panels, Optic, Heavens Bright, and Pacific Lighting Company, are leading the way.
COB's are basically the next generation of LED's, as they're more powerful, and more efficient. The also cost less than LED's, too.
With that kind of budget, you should be able to get a top notch light, for your plants to enjoy.
 
Got my cob 35 95s at 72 volts. question is the power supply

will the mean well HLG-185H-C700A power 4 of these in series? Max voltage is 264 to 286 depending on which spec sheet i look at. 72 time 4 = 288 volts. So is the almost voltage ok or do I need a different driver?
 
Bonjour
I am going to buy my 3590 from kingbrightopto!
The question is: should i take 3000K or 3500K? The highest BIN for 3000 is CB and 3500 is CD right...?
Do i have to take the 2 or 3 step?
And finally 36 or 72 V? What is the difference, except you don't need the same driver (hlg-185-1400 36V/hlg-185-700 72V) which one is the best or not...
Have a great day★

Guys at 420 told me the 300Watt Old Model Marshydro was good for my 2x2 foot growtent.
Then I found out too late that the people with knowledge are here.
Not that I wasted much money, and 150 watts is enough for now but I will go diy Cree/Vero the moment it shows signs of deterioration.

The people here are a lot better.
