Maxing out a driver, whats gonna work best for my DIY CXB3590 bar setup?

Donald Ray said:

I am a NOOB , trying to get a parts list together for a DIY CREE 3500K OR 4000K CXB3590 build. Looking at an active cooled bar configuration, I'm starting off with 1 bar and will be adding more bars to it as time goes on.

My question is what is the better all around setup for driver to cob?, efficiency, yield, photons......Etc?

4 CXB3590's powered by an HLG-185H-C1400B , Or

5 CXB3590's powered by HLG-240H-C1400B .

In a video I recently watched by Growmau5 he touched on the 5 Cob 240 setup but didn't really elaborate. Those master growers and people in the know here please help this first time old timer out would ya. Thanks!

May consider driving these at 75w idk?? If so what driver for 4 and 5 cobs ?

so that depends what the driver cost, because the only dif is the cost, both are driving each cob at 50w


maybe u mean run 4 on the HLG-240-C1750?

will that push them to 75w each?

smth more like 62- I've built a light with that set up, I think PLCs 250w bars are that combo

the cxb3590 will reach 75w at about 2100mA btw so if ur set on 75w look for the HLG-240-C2100




id suggest you take a look at some of the newer chips hitting the market in a few weeks specifically the vero 29 gen 7


i have my eyes set on those for a build next month and plan to drive those at around 115W each

EDIT: just checked the data sheet for ya pal, the C2100 won't run 4 the voltage is too high for it(i think) oh yeah because 4 of those is 300w duh


try the hlg 320
it is a constant voltage so you will wire in parallel, the bonus is that if u decide u want a lower current just add more cobs

I like 4 on 36" bars with 240-1750b cooled by 2 140mm fans powered by MW apv12-12
