Please DO me a SOLID Concerning cxb3590 Light Build

My suggestion for a better efficiency and a better spread would be:

6x CXB3590 3500K 36V ( CXB3590-0000-000N0HCD35H )
MW HLG-240H-C1050 (A or B Model)

This gives you 600-1090 PPFD (102-213W) and an efficiency of 61-65%.

hi, please do me a solid.
I know its been mentioned on this thread earlier that CB is the best bin for the cx3590
Im a total noob with led just getting my feet wet.
maybe the info still stands but from what i seem to glean today after going through crees datasheet is that BD is a better bin than the CB. Am I COMPLETELY wrong? Doesnt a higher CRI mean a better led or is it irrelevent from a growers perspective?
Also from a rank of 1 TO 4 where do the following stand.
CXB3590-0000-000N0HCB30G
CXB3590-0000-000N0UBD30H
CXB3590-0000-000N0UBD30G
CXB3590-0000-000N0HCB30H

The g and h at the ends just explain which step it is. 2,3,4,or 5 step which means how many differences on color changes the human eye can see. Irrelevant to growing. The farther in the alphabet the letters of binning the better. B*<C*. CB <CD

The bin is based on lumen count. CB should output more lumens than BD.

Higher CRI has a red peak closer to 660nm so in that respect the high CRI version is desirable, but the charts are relative and high CRI also has higher 500s which isn't that useful. Testing needs to be done to confirm which is better but the conventional wisdom is that the efficiency loss isn't worth the supposed more ideal spectrum.

thanks for all the input everybody.
I want to run a 5 cob setup. If i aim for one cob/sqft will I see a significant difference in yield if run them at 1050 A as opposed to 1400A.
