Db bins are out now,but the difference between them is minor.cd is still good.unless it came in original cree package (doubtful for 1 cob) then it will be very tough to know exactly what it is.thats a good reason to buy from reputable sources.
I tried to "unlock" some package codes, stil did not understand, which ones are they. Here is a picture. (open picture below post)
I see 35G, ok, from datasheet I know that those are 3500K.
Next, what is DB? It is probably 13`000 lumen bin, right? They told me, that they have CD bin.
Next, from NOH I found out - for 3500K that stands for 80 CRI, probably.
Next, 000B1, what is that?
I saw datasheet scheme for "unlocking" these codes, but they did not help in this case for me.
Picture is from where I bought this COB.
Please, share a reputable source for me. I bought this from alibaba.
But the fact is (as far I understand) - the lower amps, the less heat they emit, the more efficient they are (lumens per watt), right?
For example 1 x cxb 3590 @ 700ma is less efficient than 2 x cxb 3590 @ 350ma, right?
As this chart shows, if lumens per watt grows, then it would be extra nice building them at 200ma - 300ma and putting a lot of these cobs in one panel.

You can actually run 5 3590's on that 240h-c1400. 3590's will pull less than 36v and fit into the voltage range of most meanwells really well. It wouldn't be a big deal to run just 4 on that 240h-c1400 if you happen to have one already or they have a great deal. But if 4 3590's is your end goal, there are a couple better suited driver options.
If you only want to only use 4 cxb3590's...
You can use a HLG240h-c1750 and run 4 at ~62w each.
Or
You can use a HLG185h-c1400 and run 4 at ~48w each.
You are correct about the A version only needs a screwdriver to dim within the range stated on in the data sheet. No external/additional parts required. The A version drivers are more designed for setting up and not touching after setup...not so much often/continuous usage. B versions are recommended if you want dimming as a major function of the light.
Thank You
I want to build a light suitable for 1m - 1.10m X 1.60m - 1.70m AND I want to run it economicaly, so my bill is low. So, that`s why I am looking on low amps. I could try to run 8 - 10 COBs in this area and dim them to 700ma at start. I will probably end with 15x COBs
Why it says on datasheet that that dimming can be dome by A version? Nothing about B.
Simple way for dimming - 100 K OHM potentiometer?
And, another thing - if I want to see the power consumption, I could put something like this - between wall and driver, right?
Please, could someone like some of my posts, so I could use links? Need just one more.

Although the A version has a basic ability to reduce output the B version allows you to use digital control as well as a potentiometer.Thank You

You will get better coverage with more light sources but it also increases cost up front.
That power panel should be fine. Just remember that about the light it produces.
Did not understand this one.. I am sorry, english is not my mother language.

Could interfere with dark cycle. Little things overlooked can cause unforeseen trouble.
Interfere? What could interfere with dark cycle?
How much of LED`s are there?
The number of LEDs, not power..?
