First off: The CXB3070 is high bin, (BD) and the CXB3590 is high bin (CD). The lower bins of CREE are about as bad as the VerosBonjour
10 $ between 3070 & 3590...so 40 $ per 200w panel...you have it back at the first crop...in electricity saved and in yield...!
Have a great day ★
If you can source the CXB3590 CD bin for a fair price, there is nothing that can beat it in terms of efficiency OR price. It is a common misconception that the CXB3590 is expensive, it is actually the cheapest/PAR W at those levels of efficiency, which is why we use and recommend them.If I'm going to "abandon" the Veros for CRE due to efficiency, the CXB3590 CD bin isn't the only choice, though it appears to be the most efficient. Perhaps The CXB 3070 BD bin is more price friendly & still offers great efficiency ( 54+%).
I think I know an exception and is the setup i'm going for ... :If you can source the CXB3590 CD bin for a fair price, there is nothing that can beat it in terms of efficiency OR price.

Dude, quit- you're going to ruin my strategy here... I'm waiting until there's another, even sexier chip than the CXB3590- when suddenly it will be yesterday's news and finds itself sitting unwanted on the bargain shelf... and it will still be every last bit as good then- possibly better with higher bins- as it is right now.I think I know an exception and is the setup i'm going for ... :
With a 150W driver (ELG-150 in my case, but applies to all 150W drivers):
3 CXB3590 CD @50W vs 4 CXB3070 BB @37.5W have very close to identical performance. (les than 1 lum/W difference ...)
However, with KB new prices, the CXB option is cheaper. The difference in price increases if you count in holder and lenses ...
(And you have more point sources .. always better right ?)
Can you see any reason to prefer the 3590 in this example @SupraSPL ?
Looking at the datasheet, it looks like between 80% and 100% load, the ELG is ~93% efficient, although a lot of description text talks about 91% or 92% ... confusingTrue in that example the 3590 has only 2% efficiency advantage and that is probably within the margin of error of the estimate. Assuming Jerry can get CXB3070 3500K BB, that seems like a good design. The only thing that I could think of to improve it is that you could step up from 91% to 94% driver efficiency using the HLG-185 for the same driver cost/W. That would also allow you to fit 4 CXB3590s on one driver and reduce the lens/holder cost/PAR W.
I have a quote for them at 23$ a peice, ~10$ shipping depending on quantity ...Interesting I never noticed that, I was just going by the first page of the data sheet but I have never got my hands on one to test. So looks like it could be 93% vs almost 95%, not as big of a difference, but what advantage does the ELG offer?
Check with these guys...I made a mistake, its actually 40$ (39.93$ estimated) to my door step, so about 36.5€ ...
And I can't find HLG185 delivered in europe for under 60€ or 65-70$ ...
I guess if I could find them in a shop or have them delivered for 58$, I'd consider it .. until then ELG looks like a good choice to me
EDIT : They seem legit, they say they are original MW supplier and will honor the 5 year warranty from shipping date ..
Marked as a "2 year gold supplier" on alibaba ..
Probably me, I meet them at a conference and they were nice and had a good product in person. Someone on here grabbed a couple.Thanks @Greengenes707
I've seen this site (previously linked by you maybe ?), but gave up when not able to view any of the datasheets ..
They do have a wide choice of options and currents, interesting ...
... I sent an email
