Quantum Board help

I need some help boys , trying to learn this DIY led stuff and it's not clicking yet.. I'm not understanding how to match up boards to drivers can anyone help please!!! I have an hlg 480 2100 driver and 4 304 quantum boards... will this set up work???? I built a 4 board 304 with a hlg 320 2800 and it works great seems like it's running pretty soft tho... what I am confused about is I have been watchin all of growmau5 video and he says the output of the driver has to be equal or less than the output of all the cobs/ quantum boards .. in this video he used cobs as an example so I will here .. he had a driver with an output of 286v and the cobs all ran at 28.6 volts sooo 10x28.6 that means 7,8,910 cobs will work ..but 11 and. Not one of them will work... so with that bein said my first light i built with the hlg3202800b and 4 of the 304 quantum boards , according to growmau5 video this set up shoul NOT work but it DOES the output of that 320 driver is 57-114v and a single quantum boards output is around 108 v I belive ... so according to growmau5 video I should only be able to run 1 quantum board off this large driver but I'm running 4 perfectly fine !!!!! What am I missing ??????? Someone anyone please educate me!!! Thanks

If you go on their website and click on quantum board project it will tell you what drivers work with them and how many watts they put out

HLG-185H-C1400 is max I think 144 V.
So the only way to wire 2x qb304 to this driver is in parallel.
Each board gets 700ma. About 106-107V
107 x 1.4 = 150w
You should see about 175 w at wall max with this combo. Will not reach 200w as driver is not utilized completely ( which is not a bad thing ). Driver can do upto 144V I think and you are using only 106-107V.

You must be running them in parallel rather than in series.

Also on YouTube - Growmau5 has some good DIY tutorials including electrical basics. He has a whole series of training videos in a series.
GrowMau5 also digs QBs.

Another dumb question. What is the min Fv and max of the 304. I see vF on the spec sheet is that supposed to be forward voltage?

Yes, Vf is the same a Fv.

I'm thinking to put 4 on a 185-1400 do you think that would be worth it?

finally came in hooked it up and doesn't work. Lights come on very very dim internal pot have tried it all the way up and down same result. hlg 185 1400. Checked and re checked the wiring 50 times. Don't know what the problem is.

Would I wire two qb304s in series or parallel with an hlg 240h c2100b?
