If I'm correct it's by the AB, CD, BD and Z4 or Z2 in the part number, also the lumen output.
Which is better CXA3070 or CXA3590?

Well shit son...you would. That lowers the PARw a good bit. And possible build materials. But changes designing concepts a bit maybe with with higher wattage than with 3070's.
Anyways...the game goes on...thanks for the info.

cxa3070 is better if you want a low profile setup and cxa3590 is better if you want a medium profile setup.

Like this part number CXA3590-0000-000R00BD35F. As you noticed the BD that's a bin number and the 35 is 3500K and I'm now guessing the F is for the 4 step Order Code.

What would you use for a large profile? Not 5 or 6 foot plant's but 5 x 5 footprint and 3 to 4 feet tall?

By high profile, I mean tall ceilings.
Bigger cobs have to go higher up, unless you get as many big cobs as you would have gotten smaller cobs and underdrive them to what you would have powered the smaller cobs at . (if that makes sense)

Mid bin this would be top CXA3590-0000-000R00BB27F. Because the lumen rating is 9,500-10,545 instead of 9,000-9,990 lumens.

I'm actually buying from one of Cree"s authorized manufacturers. I won't buy from Digikey any more when I receive my order and everything's good I'll order more. Here's the Alibaba link to their company profile

Why is the AB have lower lumen than the BB?

Because it is a CXA 3590 AB and not a CXA3070 AB...different spectrums.

But it's the top and as for CRI goes I've read high CRI isn't what you want. but I might be wrong. I'll have to get back to on that....yourself... BB its the top bin for 2700ºK 80 CRI...on 77V... ...second AD bin... Third AB bin...
e active... too faster

Thank you I've been learning from you guys. I should've gotten the 36V CXA3590's but the next time.

Yeah, your right, the conversation had kind of fallen to: could provide a bump in 660nm and maybe some fr, but generally acted like a photon filter to achieve that, so effectively it is putting out a lower photon count than compared to the 80 cri and below

The bin is a category of total output. What ever chip makes it within that range of said bin...is said bin. Regardless of model.
For some chips hitting 9000lm(AD bin) is top because it is amazing for that wattage like a 3070 to reach those lumens. And it will show as higher efficacy(lm/w). Bigger chips could easily get into that category...but there is plenty more in the tank...and so the same bin category is just a low bin for that model like a 3590. And will be shown by lower efficacy(lm/w).

Point noted....but now I am even more confused, because the 3590 AB is 2700k......

I understand part numbers and bins he just got confused and stated the wrong info lol. I have both 3070 and 3590 data from Cree.
