Clu048 help checking first timer

So I'm hoping you guys can help me. I'm new to this led diy build and have some questions.
I was looking into cheaper leds bc well I can't afford full out set ups right now so I'm looking to do something smaller. Plus I'm only doing a 3x3 tent. And found citizen clu048 1818s. Then I found a few threads talking about the fact that they work well for the price. So I decided that's what I'll do.
I found northerngrowlights.com that have clu048-1812 plus holder for $20. Which I thought is a steal. I wanted to do 4 of them on sst105 passive heatsinks.
Now my question is it says it's fv is between 47.2- 52- 56.2. So if that's the case I want to make sure I can run 4 of them off the hgl-185h-c1050. Because the other one I could was running 3 clu048 on a hlg-80h-c350. And if I'm totally wrong what driver should I use for 4 clu048's
I'm not sure if I did the math right and I wanted to make sure before I ordered anything. This community is the shit and really helpful, knowledgeable, and informative. And I'm sure someone can help me get this started. I'm looking to order and build within the next week.
Thanks!

I asked a similar question about the same driver to another member/advertiser here, @CobKits.
"well you have 190V to play with which is nice. you should be able to get (5) 1212s on there, or (3) 1818s or (3) 1825s

the 5 1212s would fill it the best, (and theyre cheap)"
He has good prices as well

I just started a new thread to have a higher chance of being slighted. I usually don't have much luck with responds. I'm checking it out. Thank you
