ok so im ok with 100w per board if i used the 1750ma drivers but then you say fully utilize the driver like it i dont use up all the power is this a bad thing with parallel wiring ? i have more of these drivers than anything else in my collection right now and would like to use them.but...i also have some other stuff i can use if the 1750 is foolish? heres the pile im willing to take from for this qb project
So if any of these other drivers get me close to 80 to 100w per board im happy to use them?

Most of the answers you seek are in post 1. And the rest are on the front of your Meanwell drivers! So for a start the lower left pair of drivers...each (HLG-240H-C1050B) can power 2 boards in series at 115 watts each.

A couple concepts i have been milling over since i seen these damn things
Both would use cree 2700k cobs
#1 has just 4 on the corners @ 62w each
#2 uses 5 x 50w cobs and makes the fixture kinda wide @ around 40 inches but maybe thats not a bad thing.im trying to cover about 4.5 x 4.5 or 5 x 5 like a gavita will @ 750w
Feel free to toss out any thoughts,pros/cons to these 2

quick ? here. Does the led driver pull the max that it can from my ac side or just what the led's can draw.
I grabbed an hlg-185h-1400a and when i turn it to max power my killawatt meter reads 200 watts which is right for the driver but the board can only pull 116.6v *1400ma = 163.24.
so you can see why i ask

Good to know the think tank is going on ... I have a special build coming ( ordered boards - waiting on heatsink restock ) and will finish as soon as the complete panels come to me.
( BTW ... How about pulling 4 heatsinks from your kits so i can buy them ?? ... LOL ) .
WINK WINK ....
As far as something to " think " about for future boards .... You kind of answered that with your homepage - you have the spec graphs on 3000k /4000k /5000k and if you combined a mixed panel of those ........... Just sayin ... Lol ( samsung LH351 )

I think only simplicity. I like using the fewest drivers possible...but like sixstring2112, I have quite a collection.

Do you have the ability to measure the current going to your board?
WARNING: If you do, do not try and hook up your current meter with the board running!

I want one. LOL! This looks good. Make sure to do your own journal when you turn this on.

Only throwing out an idea with a board with those combined spectrums ... Instead of a single kelvin board but a combined one. Since samsung led engines are available from 6500 down to 2700k in their LH351 high power.

I plan to do exactly the first option! I already have two, 50 watt light engines, with citizen-1818 cobs, from cobkits in 2 corners of a tent and plan to add two more. Then replace the shitty burple I have with 4 Quantum boards.

Hello again peeps. 
When getting optics for these, is it one per row of diodes? So I would need 8 per board?

No 3 per row I made the mistake of only buying 8 but I don't like them so I won't bother ordering moreHello again peeps.
