Yea you can run 2 cxb3590s 72v on one of those drivers. They are rated 143v, so running in series 72v+72v=144v but the driver can handle 1v difference it will just drop the current slightly to compensate. I have run 72v cobs like this, 2 years still working great.

Raz say me it's ok i can use 4 cxb3590 72v on hlg-185h-c1400 like the schema attached in my post.
I just add two 1A fuse for protection.
I want add 4 cobs to my setup for 8*50w it's better efficiency than 4*100w.
What's aera i can use with this setup ?
What's good distance from top plants to COB ? Because with my 4*100w I burn plants when I am at 40 centimeters from top plants.....
Thank's before for your help.

Your better off with 36v cobs if you want to run more cobs at lower current. I suggest a bunch of Citizen Clu048 1212 Gen5/6 @ 25/50 watts each. In some cases you can get 3 of those chips for the price of 1 cxb3590.
