Can't wait, is there a pre-sale on it somewhere?
I'll love to test them.

I am looking for one driver to run 3 CXB 3590 36V @ 2.8A and also one driver that runs two at the same efficiency.

Any suggestions for a 200W single driver bar? Or a 300W single driver bar?

Or should we just wait until April?

I order custom drivers from china to drive the cxb3590 36v @ 2.8A. But their efficiency is bad. 87%!

I would love any suggestions.

Cheers

such high current it starts to get very inefficient though right..2100 is 49% i think maybe even little lower..1400 is 56% 1050 is 61%

I think they are made to run a bit more hard... Otherwise I would go for the 3070s.

I am not a LED guru, I know it is not the best way to run them, but when you need to save a bit in COBS, that is a great setup for a DIY bar. (I think)

you can buy this now for $100:

you might need the 42V version to run them at 2.8A

What do you mean? Just to have a bit more voltage, 36 is cutting it to short?

Can I run 3 and also 2 Cobs per driver? 36V CXBs 3590 @ 2.8?

yes thats a high current driver you run em in parallel not series

NOOB ALERT
What is the difference between the 320-42 and the 320-2800 then?
They way you wire them?

Another question:
What would be the perfect driver to run two @ 2.8?

the 'C' in the HLG-320H-C2800 means constant current. which means if you put 1 or 2 or 3 cobs on there (in series) and they will each run at 2.8A. 4 wont run at all as the voltage is too low

the other driver (HLG-320H-36B) is a constant voltage driver (36ish). cobs are wired in parallel
you hook one up, it blows up
you hook two up, they blow up
you hook 3 up, they run at 8.9A/3= 2.97 A
you hook 4 up, they run at 8.9A/4= 2.23 A
you hook 5 up, they run at 8.9A/5= 1.78 A
etc

Here's some Mean Well designations;
A= Dimming(Internal)
B= Dimming(External)
C= Block Connection - Unwired
D= Dimming (Timer) - *Usually custom
E= Steel Compatibility- (?)
Blank = No dimming

but those are the meanings when found at the end. A "C" within the model number usually means the ability to adjust the current and voltage (mix mode) depending how your design is running. Drivers like that are not something I play with :dunce:. IDK if the average person wants that ability as the way it works. See models CEN-75 or the CLG-100 as examples.

Edit: Actually I think you are correct that it's CC. Seems if there is a C at the beginning of the last set of numbers it does designate CC. These companies and their naming conventions grrrrr....:twisted:.
