if it has a 12V fan, yup
Could you post up what variety of drivers to power these chips? Deciding whether to stay with 3590 or upgrade, but don't know the new numbers.I wanted to wish a merry christmas to all you cobbers out there. this weekend only:
1212 $10 ($9.00 after RIU code)
1818 $22 ($19.80 after RIU)
1825 $40 ($36.00 after RIU)
The datasheet http://cobkits.com/wp-content/uploads/2016/08/HLG-120H-SPEC.pdfJust looking at your site. Curious.
From the HLG120H-48A page you have this:
rated current: 2.5A Max current: 2.95A can power the following combination of COBs:
Citizen:
2 1212@ 54.5W each (109W max), [email protected] ea (105W max) , 4@ 25.6W ea (102W max), etc.
2 1818@ 78.5W each (157W max) or 3@ 50.7W ea (152W max), 4@ 37.4W ea (150W max), etc.
2 1825@ 76.4W each (153W max) or 3@ 49.7W ea (149W max), 4@ 36.8W ea (147W max)
Cree:
2 3590@ 76W each (152W max) or [email protected] ea (149W max) or 4@ 36W (144W)
2 3070@ 79W each (158W max) or 3@ 50.5W ea (152W max) or 4@ 37W (148W)
I know this is YOUR recommendation but why? You are stating that you can drive 150+w from this driver but it is only rated @ 120w?
there are literally hundreds of drivers that can run these chips, im not sure i have time to post them allCould you post up what variety of drivers to power these chips? Deciding whether to stay with 3590 or upgrade, but don't know the new numbers.
Well aware of that thread and how to figure what driver can run what.there are literally hundreds of drivers that can run these chips, im not sure i have time to post them all
1212s are ~34-37V and basically you can fit as many as cxbs on the same driver. not sure 1212s are an "upgrade" (while great to add i wouldnt replace cxbs with them)
1818 and 1825 are ~50-55V so you fit that many less on a driver. so if you have say 220V available on your driver youd get 4 50V cobs on there as opposed to 6 36V cobs
heres a good place to start:
https://www.rollitup.org/t/matching-drivers-and-cobs.883866/
start there and if you come up with any specific questions we'll be happy to help.
the HLG-185H-48A is the most popular driver on my site because its cheap, flexible and the math is easy. it runs up to 53.5V and is perfect for the 50V cobs. You have 4.2A to split between whatever cobs you connect to it (in parallel). so 2 cobs at 2.1A each, 3 cobs at 1.4A each, 4 cobs at 1.05A each, 10 cobs at 420 mA, etc.
sure it can, those are all real numbers. nothing up there that hasnt been tested by me. Take a look at meanwell's test reports, any of those numbers can be verified with a meter on an actual setupEven at "max current", the HLG120 cannot provide those numbers.
because you can? because you want to get the most out of your driver? same reason you would run an hlg-185 @ 225W or an HLG320 at 400W or an HLG 600 @ 720W. if youre not exceeding the 70C case temp there is zero reason not to.Just looking at your site. Curious.

ive only got a few 4000k. i dont stock cree, i gave up I sell maybe one chip for every 100 citizens, too expensive to stock to watch them sit on the shelfNo cree?
Oh, wall draw... Because that is the same as actual power to the cobs. Please show me where someone is delivering those numbers to the actual cob. I am running lower than 50c and my 185s arent putting out those numbers. Maybe at the wall yes, not actual delivered to the cob.because you can? because you want to get the most out of your driver? same reason you would run an hlg-185 @ 225W or an HLG320 at 400W or an HLG 600 @ 720W. if youre not exceeding the 70C case temp there is zero reason not to.
no not wall draw, dc sideOh, wall draw... Because that is the same as actual power to the cobs. Please show me where someone is delivering those numbers to the actual cob.
Like I said, I draw 222w @ the wall with my HLG185-C1400B drivers. That does not mean I am outputting more than 200w DC side. It takes electricity to power the driver itself and convert to DC power.
sounds about right. its almost impossible to fill out the voltage on a constant current driver. the 50V cobs fill a 48V driver to near the limit which is a fortunate coincidenceBy all means, throw a multimeter on it and show us. 185h-c1400b is what I am running.
