CXB3590 DD bin where to find them?

Anyone have a source for DD bin? Are they just now coming out? I asked jerry and he does not have any and will not in the next 4 months. Best i have seen are DB and they are extremely hard to come by. I finally decided on the light and now i cannot source the COB's anywhere. Was really looking forward to the 70% efficiency at 1.05 amp.

they dont exist for purchase in the wild but there are other chips that are brighter than a dd would be.

ive never seen a 3500k DB
4000-6500k DB have been around for a long time and are not at all hard to come by

ive only heard of one DD and thats a one-off small lot of 5000k chips that realstyles got from jerry

Still waiting on the spherical test results as you keep claiming this. Oh wait, you want US to chip in for that testing to sell your product.

Not saying they are not better but get your own testing done and prove to us. You keep trying to sell these cheaper chips. Very few products in the world are cheaper than others when they are better quality (and by the the amount that CITI is saving, big gap there for the "better performer"). Seems you could up the price just a little to pay for your own testing.

Waiting...........

keep waiting, thats fine, i have no plans for that. Current citis will be obsolete in 4 mos anyway, and CXB3590 also on its way out so no point in testing. But you can hold out hope, theres a chance that my testing is wrong as is robins and malocans. maybe we all had a bad batch of crees or something. until someone shows a single cxb in the real world beating these chips its the only data we got though.

you could also buy the vero, getian, etc chips that are a gen ahead of CXB. i dont sell those so i have no agenda there. in any case i dont claim, that citis are more efficient because i sell them, rather i sell them because they are more efficient, and if i find a better value out there i will offer it. Theyre not all that cheap i dont even stock their flagship $60 chip that is more efficient per watt than any chip on the market that we know of.

sorry for answering OPs question. wouldnt hold your breath for DDs. i thought for sure wed be into the new bins 4-6 mos ago... Realstyles had that DD last year. ill bet they only yield a few percent of those in a batch.

in any case id advise OP to consider spectrum as well. its likely that we only see 5000K and up in DB. *maybe* 4000k 70 cri. Dont expect it for the better spectrum chips like 3500K and 4000K 80cri, as those are only CD currently, and DB would be a jump

By all means, post up YOUR Citi grow with details and pics. Would love to see you prove your product is worth it. Not saying Cree is the end all but you keep pushing your product with nothing to back it up. Cree COBS have been around for quite awhile.

how would an anecdotal grow demonstrate value over cree? i guess i dont get the metrics

heres that if youre looking for it

https://www.rollitup.org/t/northern-grow-lights-photon-180-clu1825-grow.915159/

HPS MH T5s and blurples also have been around for quite a while. Ive seen some fantastic results from all of those.

i kind of think you are saying cree is the end all with nothing to back it up, well suggesting it at least. Logically, they would have to be, to command the premium they do

for sure. i never believed in cree but jerry's garden was something to behold. really put the cred i was seeking behind his chips. but seriously, putting it to rest, have the last word if you like.

Never believed in Cree? How long have you been around? Cree has been around for years and years....

I stand corrected. to be fair im sure there are 100+ patents covering all aspects of manufacture but thats neither here nor there. im sure cree, citi, nichia, sylvania, bridgelux, samsung, etc, all have patents they license from each other

Citizen is licensing more from Nichia and Osram than the other way around. indeed Citizen is bound to have a patent here and there too, but they are of far lesser value since Citizen got sued and settled.

The main patents are in the hands of the first ones to produce these types of "white" leds. Like for instance a Nichia employee creating the first viable blue led and Cree being the first to put flourescent coatings on them

Are they brighter and equally efficient? If so what would you recommend? Makes you wonder what they are waiting for to release the DD. I am primarily looking to build the veg light in about 4-6 months so in no rush just making sure all of my research is down long before i am ready. I rather go with top of the line and spend a bit more and it not be outdated in 6 months.

really hard not to build anything from any mfr that wont be outdated within a year. id wait and see what the best chip is in 6 mos. never advisable to buy electronics before you need them (that said, if youre replacing somethign inefficient like T5 get on it, you'll recoup the cost of the chips relatively quickly)

we may never get to DD in 3590, hard to say. if and when it does happen they will prob have a new line out. it would be nice if they could improve the 3590 and keep the same package size for all the people with existing infrastructure. citi has done this for a few generations, with the clu044/045/046/047/048 and 056/057/058 series.

well efficiency numbers are moving target as they are generally specd at a nominal wattage. so for example larger more expensive chips are specd at a higher wattage than what we would use them in. that said the larger chips way overperform in the 40-100W range we like to run them

id personally go with citi 1818 ($24) to match a $40 CXB, new vero29 ($23-31) or citi 1825 ($40) to beat it. some people like more smaller chips, like the citi1212 which is about 75% of a CXB and is a $12 chip. one of them doesnt beat a cxb but 2 or 3 sure do, and are cheaper and better coverage

ask in 2 mos and you might get a different answer

so who sells em? they must be shipping on DB order code as searching google for CXB3590-0000-000N0BDD50E yields nothing and its still not on the datasheet.

do DB 80 cri exist yet?

I was under the impression the citi 1818 was not even cracking 50% efficiency at 1.05? While the CXB DB are hitting 66%? I rather worry about the cost of electric adding up than the cost of building it. Sorry i meant i will not be looking to by for 4-6 months as it will only take a few days to throw it together. Thanks for all the help i really appreciate someone who is willing to help like you.
