Doesnt look any more scraggly then your buds in your pic. But thanks for your opinion
Your CXA3590 Mission Should you Choose to Accept It !

Lol. I wasn't here!
Well actually I was and I noticed some drama unfolding. Seems really common this past week. Not sure if I'm just now noticing it as a ordinary trend or if the saggy weather is bringing people to the brink of bashing in the skull of their fellowman!

Yeah that's why I never post too often, haters are going to hate. Shows a lot about them behind a computer
hi ,
Nice stuff here man
Its been some months now I am looking for a cxa3590 DIY .
And your topic's title match so good , so hard to find an driver for this cob lol
I wanted to have the possibility to adjust volt and current with dimmer so , range between [email protected] and [email protected] ( max usine value I think )
And after many research , many read ( this topic include and it helped ),
many mail send and phone call , here is some results ;
Guy from Cree give me this 2 drivers , mentioned in this topic :
EUC-150S175SV 150=W ; 175 for 1750mA
EUC-150S140SV 150=W ; 140 for 1400mA
from Inventronics
Note that the "SV" series, after have downloaded datasheet , seems to be the dimmable series.
Anyway you can't find them in stock anywhere...
There is the "DT" ans "ST" series , but I don't have much competence to know the difference
and he mentioned also the Philips Xitanium series :
http://www.futurelightingsolutions.com/en/Technologies/Semiconductors/Lighting-Solutions/LED-Driver-Modules/Pages/7020595-LEDINTA1500C100DO.aspx?ManufacturerName=PHILIPS-LIGHTING&isFLS=true&IM=0
So , one thing I would like to know , the cxa 3590 voltage max is between 77V and 84V right ?
Si if I understand well , its the output voltage ( and current ) we must to see if this driver match the cxa3590 value right ?
but on this driver , the Min. Mains voltage operational : 108 V
That means that the driver adjust himself the Voltage to matches with the cob ?
And the dimmer is just to adjust the current ? (and if this one is adjust ,the voltage will automatically change for the right values from amperage ?)
If not , why the Cree guy told me this driver is compatible ??
after , from what I asked just before and what I found that would be compatible with cxa3590 :
- http://www.macrongroup.com/led/products/product.php?cid=52 ( output [email protected])
- This one looks good , but not dimmable ( dunno if possible to install dimmer )

Anyway , can you tell me what is the stuff you are using to dimmable with the HLG120H1400 plz ?
And what is the thing who we can see the V and A you have ?
Thank you

If you use this tool you can get the exact voltage @ chosen current and vice versa:
http://pct.cree.com/dt/index.html
The 77v 3590 is tough because not many drivers match up neatly with the provided voltage.
With the 120h-1400a you adjust the current with an internal pot and the voltage responds accordingly. With the 120h-1400b you adjust with pwm i believe but ive never used.
Unfortunately with either model you are paying for 108v @1.4a but you are only using 84v @1.4a. (Experts correct me if im wrong)
Fortunately there is not much efficiency penalty because with that model anything over 50% load is going to land you in 90% efficiency range.
I have no experience with vero 29s but it is my understanding that if you are looking for a high power chip at this time the vero29 is much better value.

Thanx guys , I think I get it,
for this one by example , http://www.digikey.fr/product-detail/fr/PDA125B-1A4F/993-1276-ND/4833136
the output voltage is 67 ~ 89,3 V , output current max 1.4A
So a 3590 on it , would run at [email protected] ?
or its at 89.3V that the current is 1.4A ?
That mean the 3590 will run like [email protected] or something ?
Cause this driver isn't dimmable , so he will adjust by himself huh ?
and does it possible to put an external dimmer on it ?
edit : in fact can we make a dimable driver with an driver which isn't dimmable ( no 1-10V PWM ect ... )

@dimebagor. Going to be a cooling nightmare though..might be better off driving softer.
These might work...they are a tight fit on specs

DB, as you probably know the CXA3590 dissipates a lot of power at 1.4A, about 112W. The CXA3590 efficiency is mind blowing when running soft and cannot be beat in that situation, but when it comes to driving them hard with large dissipation, the Vero29 really takes over.
Here is how they compare using the "typical" figures
CXA3590 3000K BD (top bin) at 1.4A is 35% efficient and cost $1.42/PAR W.
To match the cost of the CXA and increase efficiency, at 1.4A the 3000K Vero29 is 41% efficient and cost $1.53/PAR W.
Or to beat the cost and efficiency of the CXA, at 2.1A the 3000K Vero 29 is 38.1% efficient and cost $1.06/PAR W.
So if you are not set on the CXA, you might be able to do even better with the Vero in this case and drivers would be much cheaper as well. Also, do you have a lead on the CXA3590? The 3000K BDs might be tough to comes across. I think Digikey had the BB bin.

Thanx guys for all the help and informations.
@Positivity : For the cooling , I found some test/review about his .
The soltion choose by JavaCo looks good , I will put a noctua ventalitor nf-p12 on it will ok .
Or I was thinking , for the style , to get an AIO watercooling ENERMAX Liqtech 120X , this one can dissipate more than 200W
For the driver you have found they looks very good and very cheap ,
It would make something like :
-cxa3590 : 56$
-driver : 30$ max
-cooling : 50~80$
wires ,solder, dimmer ect .... total cost 136~200$
But does this driver are SAFE to use ? I mean they wont burn after 2 days use because its Chinese stuff ?
@SupraSPL : reguarding the cxa3590 ive got some choice :
the CXA3590-0000-000R0YZ430H but its 3000K
http://www.ledrise.com/product_info.php?info=p3562_Cree-CXA3590-warm-white-10511-lm.html
or the CXA3590-0000-000R00AD27F-ND
http://www.digikey.fr/product-detail/fr/CXA3590-0000-000R00AD27F/CXA3590-0000-000R00AD27F-ND/4501389
I didn't found anywhere other cxa3590 in 2700K in any other bin than AD
About the Vero 29 I am looking for now, the specs is :
for 2.1A ; min : 35.2V
typical : 38V
max : 40.9V
for 4.2A min : 37.3V
typical : 40.4V
max : 44V
So I was searching for some driver and I found this :
http://www.digikey.fr/product-search/fr?pv48=5881&FV=fff40009,fff804be&mnonly=0&newproducts=0&ColumnSort=0&page=1&quantity=0&ptm=0&fid=0&pageSize=25
but I dunno why they say 40W , whereas 42V*2.2A = 92.4W
am I wrong ?
or this one
http://www.digikey.fr/product-detail/fr/PLED75W-036-C2100-D/1121-1207-ND/4271598
not really efficiency ( 89% ) but not too much expensive
Does I'm right bout this 2 drivers for a single vero29 ?
Should works with cxa3070 too huh ?
PS
Gotta to say , I 'm selling ALL my old lightning stuff ( cant do more with that noise and all the place it takes )
It means 2MH 600W sunmaster /2 hps 600W , 2 lumatek 600W ballast , rvk 900m3 + 2 cooltube + silencer ect ...
it will make enough money even sold at half price from non used stuff , to help me to finance me a DIY.
I just want an light for bloom only .
I'll do veg with 2 hans panel 65W ( what I have already done ) it works so well
So I was thinking , put 3 or 4 cxa3590 you know ( each one with own driver ect ... )
maybe 2x3000k CRI90 with 2x2700k CRI80 ,
or 1 CRI90 and 2 CRI80
or full 4x2700k CRI80
For 4 cxa3590 complet kit ( cobs , driver , cooling ect ) it cost me something like 800$ but with € conversion , its like 600$
just driving at [email protected]
its 90Lumen/w ; 112W power ; 4 cobs = 448W for a total 46k lumen
it will cost little bit less with vero29 , about 100-150$ , but the power will be affected too .
4 vero 29 is like 250W - 300W maybe ?
after this , I will update in the future by completing with color led to increase the spectrum
Thanx again for help all
Hope it will help some who are looking for a DIY very high power COB led)

@dimebagor
Ill be testing the chinese drivers soon. You can take a chance or wait till i get it put together and see how it goes. Soon as the parts arrive.
But...I'm doing this more for learning and the fun of it. I wouldnt expect it to flower better or be cool enough compared to a more conservatively driven setup
Not sure I'd mess with watercooling, there are aircooled options that get close enough to what the water can do. I was tempted but decided against it.

For the Vero29, you could use 1 driver per COB and yes they would work with the CXA3070 as well. This is a decent driver and cheap. About 1450mA, 89-90% efficient and power factor corrected.

Are you shipping to US or elsewhere?

@Positivity
Haha , man I really hope will be alright.
A friend of mine , bought some Chinese stuff ( from alibaba ) , stuff like sander, drill, ect ... can tell you , its not really good quality.
The drill had worked for 2 months by example , and button was inversed ....
Be careful dude , if you decide to go out from home for couple of hours, I won't let this things run without keep an eye on it
You right about watercooler , I would like to have one , but one thing crap with this AIO or DIY ; if the pump break , the cob will burn.
So I think I choose like JavaCO ( except if I go on vero29 )
@SupraSPL
Thanx for the link , was difficult to see , it was acces restrict from where I live
Anyway , it looks like Chinese stuff , man ,
If I go vero29 i'll take the Thomas research , run them at typical value.
sure its 45$ ... and yours its 7$ (the 50W aren't in stock by the way) , but its same stuff as Positivity link
But , I admit , I hesitate ,
from 128$ for 4xvero29 with Chinese driver to 280$ with "quality" driver
10xvero29 with Chinese driver = 4vero29 with quality brand driver
...hhmmm
But we are talking about electricity , its not trivial ,
if I'm wrong , I'm totally stupid , and lost some money , but do I got enough balls than you to take a risk without Chinese driver ....
I think I wont ship in US or other , it would cost so much , I will fond someone on place directly
In last case , if I really dont find someone , I 'll do ship , but in US , serious , I don't think its worth it
In all case , piece by piece or complete kit and bout this last , man,
4 lamps , 4 ballast ( 2 elect and 2 normal ) ,the silencer (which is so big ) , 3 extra ( 980m3 ;600m3; 300m3 ), lot of meter of shrink sleeve , 2 cooltube
1 carbon filter , 2 closed reflector , man I let you imagine the price of the shipping

Lol?
Supra is the supreme ball master; all who want balls must first go through him.
haha,
God bless his balls
Its just I don't trust in Chinese stuff , more about electric material.
Sure its supposed to works fine , your home wont gonna burn and no one will go die, BUT ,
its usually shit stuff , like if you buy some 125cc Chinese and go on road withtout verification, you will have lot of surprise after few days only ....
Sure the 125cc cost 1000$ non used ... no doubt on why so low price ....
But , I feel the balls grow up in me gradually , the price is so attractive !!
So strong this Chinese people.

Hey DB, I did not even notice the 50W was sold out again LOL. Can you get shipments from AliExpress? There are lots of 1.4A drivers there that are good efficiency and power factor corrected. I agree with you, the Chinese stuff is not always up to the quality standards of name brand drivers. Some of them are decent drivers for the price though and hopefully the name brand driver manufacturers will copy what the Chinese did but with higher quality components. For example, the basic 1.4A driver from Mean Well that can power a CXA3070 is not power factor corrected and efficiency is only 85% (LPC-60-1400)
This one is cheap, although I have not tested them yet for efficiency or Vf range
Some of them say max 38V but they go up to 42V which is helpful for the CXA3070. The Vero29 should be easier to match.
I have been ball-burned at least one time. I ordered a 1.5A test driver from Sure-display on eBay, decent seller good feedback. It tested very well so I ordered a 5 pack. The 5 pack shipped from a different location and they only put out 700mA and they we 83% efficient (obviously defective junk). So I complained (politely) to the seller and he talked me into sending them back to China at my cost (I was a fool not to turn to eBay at that time). He received them and claimed that there was nothing wrong with them and offered just enough to cover the shipping, which I refused. It dragged out and I got zero reimbursement. Then the seller blocked me from his eBay auctions. Another RIU member ordered a big batch and got burned also, but he turned to eBay and they took care of him which I am very glad!

Sorry about the thread guys , but to medical issues I had to take some time off and get well. Getting old sucks ass. Worked out in my outside garden today for a few hours and I am Completely pain free. So things are looking up. Didn't get any pictures or document the grow like i wanted.
Dimebagor I dont know of any drivers that will 1.8 amps with the cxa3590. But it looks like you might have some China Options from the posts. Cree has a 36 volt version of the 3590 now. Still tough to find it and a driver for it though, since it requires 2.5 amps @ 36 volts. Meanwell has this driver that is new http://www.meanwell.com/webapp/product/search.aspx?prod=LPF-90. . I really havent looked into it much since i have decided to jump ship and build a vero light. Got parts coming in for it now and hope to have it built after the first of the year.
The HLG 120 c1400b is dim-able via a external 100k pot but that is the B version of the driver only. If you got the A version it has a built in pot on the driver itself which might be a better option for some folks. But really it is Pretty expensive way to get a 90 watts or 110 watts if you crank it up to 1.4 amps . These drivers are 70 bucks a piece. They are also on the big side so getting a bunch of them into a enclosure is a chore.
The volt / amp meter i have hooked up can be found on Amazon Ebay and alibaba. They are about 5 bucks shipped off ebay. Reason It was added to the light was just so i could know when i was @ 1.2 amp because I wanted to run it @ cree test specs. Plus it is just nice to know what Watts the LED is running at. Here is a link to one http://www.ebay.com/itm/Red-Blue-LED-DC-0-100V-10A-Dual-Digital-Voltmeter-Ammeter-Panel-Amp-Volt-Gauge-C-/321543047014?pt=LH_DefaultDomain_2&hash=item4add758766.

@SupraSPL
Wow , this story with with Sure-display really sux dude:/
But like I will say , the cxa3590 cost too much due to the driver ....
Hello JavaCO ,
Thanx for the help
Yeah , after months research , for the cxa3590 (77V) solution , well I will buy Chinese driver, found by Positivity.
Even if , yesterday I have success to find some new others driver that match the cxa3590 , here we go :
About this one , I don't know at all what kind of driver it is ??
http://uk.farnell.com/tektronix/pws2721/power-supply-1ch-72v-1-5a-adjustable/dp/1824786
this one must work , the description of max 25W must wrong huh ?

http://www.erglighting.com/index.php/drivers/genlume-collection/xla-series/100-watt-xla-series/xla-100w-172v-cc-250.html
this one looks perfect to but look at the price lol

http://ecatalog.astrodyne.com/usa/led-power-supply/DR120-086S140
this one is surely made to run several cxa3590 I think , correct me if I'm wrong
http://www.eptronics.com/ldad120w.html
The only problem , its the price , very too much expensive :/ ( except for the roal electronic on nerwak )
So , can we tell mission accomplished for cxa3590 driver haha ??
anyway thanx for the help you guys , Java , good health recovery dude
Keep going on'

So i want to build a DIY Cree 3590.. Now i need some advice. 4x4 tent most flowering, however it may become both, and I want to build a light that is suitable for the size, 4 plants, maybe 5, and i would like it to do both flower and veg.. So I need some recommendations for what chips etc.. I'll be using the meanwell 1400 driver. Also any ideas on heatsinks.. I was thinking about 4-6 COB's.. Discuss
