Supplamental cobs, which driver

Hello. I recently bought 2 qb288 for my grow tent (2.5×4) and was thinking about adding some cobs to reach the 35w/sqft range. I am probably going to add 4 citizen048-1212 or 1818. One for each corner of the tent. I was wondering which driver I would choose to power these. I am still a bit confused on how the amps and voltages work on them. Also would I go with 80cri 90 cri

If I powered 2 cobs citizen1212 each with the hlg-120h-36 would

4 1818's can be powered really nicely with a hlg-185h-48A driver I prefer 90cri personally. Youll be able to max out at around 55w/cob but its adjustable to less than half of that.
