Board/ driver wiring

i have 4 Samsung boards LIKE not the same but same config as a qb304 and was wondering if I could wire 4 to a 185-1400 driver?
I have 2 on heatsinks and 2 not being used but would like to use all 4 with no heatsinks or at a push steel plate maybe.

Is this even possible?
Would ideally run them at 50w each with my 9 cobs

what is the voltage of them at 1.4/4 A? i think it will work from what i remember reading about the regular QB being able to drop to 30-50W no issue. edit i just read that they can be powered as low as 10W and the 185-1400 range is 70-140 or so. The QB @ 25w is 100v there abouts. i would gander that the voltage range isnt very wide so i dont think it will drop below 70v... should answer your question.

All I know is they are 110v or 115v at full power I believe inline with the qb304.
Didn't know weather I should run all parallel or 2 parallel 2 series or how they should run

Seems that I could run them all in parallel for 170w so 42.5w per board which would hopefully mean I wouldn't need any heatsink

depends on the max voltage of the driver you are going to use. If it will go over 220V DC then series is fine, otherwise you'll have to do parallel.
