Interesting conversation. By way of contrast I've placed a bet on CXB3590 3500k from cloner to chop.

I'll be very interested to see the results of a comparison.

@SupraSPL or anyone who feels confident with the material;

I ordered CXB3590 3500k CD bin 72V, to go four at a time with the appropriate 200W Meanwell driver. This combo has been spec'd out to be 56% efficient.

Now I'm hearing about a 5 x CXB3590 combination running at 61% efficiency.

Can you or anyone explain this five chip setup in a bit more detail? Would it be worth the switch from my current combination?

it's just a different driver at a lower current. i'd say stay with what you already have bought...there are an infinite number of combinations so I wouldn't worry about 5%, which is probably negligible when measurement error is considered.

I wasn't planning to shred my current build sheet, but I am building another panel.

If I can get an extra five points without a lot of extra expense, I'm interested.

Can you give me a few more details about drivers, operating wattage, etc?

Yeah man, if you're building another light, might as well go for it!

I can give you those details, but I usually don't, sorry man! It's not personal, or that I don't want you to have a light, but if you learn the general ideas, you can easily figure this out:) It's really simple!

Think of the COBs as low value resistors that add in series...take the number of COBs, multiply by voltage desired that corresponds to the current you want(by reading datasheet, or posts), which usually corresponds to some desired efficiency, and then find a driver that can supply that voltage:)

You will maximize the efficiency of the driver if you use almost 100% of the power it can provide (by getting the total desired voltage near the max V output of the driver). This comes at a cost of lowering the lifetime of the driver, but you can increase the lifetime by lowering the voltage drawn by the circuit. It's a balance, and usually drivers last a long time, regardless. This info is in the datasheet for the drivers :)

Well then, since I'm in no mood to become my own expert at DIY LED (I'm pretty damn covered up with what I'm already doing and I outsource the lighting equipment manufacturing as it is), perhaps someone else can provide more specific information?

Sorry man, but it's never a good idea to assume the other guy has plenty of free time to learn electronics from the ground up.

I'm a specialist, and I hire people like me who also specialize- in the jobs I need doing. It's called 'delegation of tasks' and it's a very helpful concept in 'project management'.

Anyone else?

@SupraSPL

I wanted to say thank you for all the support you provide. I would not been able to do a DIY build without your help and the help of so many others, here are a few

(REALSTYLES,captainmorgan,Alesh,Littlejacob,Tim Fox,Growmau5,Rahz,BM9AGS)

I ordered the 5.88' profile heatsink from HeatsinkUSA, CXB3590 3500k and drivers from Jerry. I spent the weekend drilling, tapping, mounting cobs and wiring my first light. I went with 4 lights on a 40" heatsink at 50 watts each. The panel draws 204 watts from the wall and the heatsink is only warm to the touch :) Passive! Love it!. I plan on running 2 of these and a 30" heatsink with 3 Cobs in the center (11 Total) in a 4x4 area.

My rough estimate on PPFD is 850 over this area??

Great design and yes I come up with 867 PPFD averaged, but if your drivers are A version and adjusted to max, it could be as much as 930 PPFD. That should grow some monster buds :leaf:

Back in the beginning pages of this thread, you posted some driver and chip combinations with efficiency, PPfd, wattage used and cost per PAR watt.

I did not see the five COB combo anywhere. I'm looking for a similar summary, to see where the 61% efficiency comes from?

1050 ma Drivers don't seem to be a popular choice,most go 700 or 1400 ma. I'm doing 800 ma but may do a 1050 ma build in the future.

I went with the "B" version and added the external 100K pot. My soldering skills are very rusty and I killed two before getting one right! I drilled and tapped 4-40 with a hand drill. Slow and careful and I managed not to break a bit or tap.

I need to order the 3 center cobs. I was thinking of mixing it up and going with 2700 or 4000 or ?? How is your testing coming? I will use the setup from seedling all the way through harvest.

Thanks again!

I bought a 10-pk of pots. I am basically blind at least according to DMV.
The pots came and are the size of my thumb nail.
I have an old piece of junk soldering iron non adjustable 35 watt...15 min to warm up. Anyway glad I got a 10 pack....
