The price difference between qb and cobs depends on the exact cob family you want to use.
Im not going to work out the price differences for you but a few suggestions on cobs are all for a 4x4 all @1.4A
12 citizen 1212 = 8 citizen 1818 or 8 Luminus cxm22 = 12 vero 29 or
4QB 2 hlg-240-2100 divers

exactly what i was looking for mate. thanks i work out the rest.
one more thing
would 6 QB be an overkill for a 4x4 tent?

Depends on how hard they are driven
I would stick with 4QB and 2 slate 2 heat sinks 2 divers @2.1A that is about $600 for a 4x4 light

Who's doing your reflow soldering?

would the 2x hlg-240-2100 drivers be better than the ones recommended by the webshop -> hlg-240-c1050a ?
would the 2100 need additional fan if i want to drive the boards harder? and one last question and i promise i go away
in the webshop they have a lot of spectrums for the boards only the 3000k voltage binned ones are available. are they the ones i need ? not really sure what voltage binned means to be honest.a simple yes or no will do as answer.
as soon as someone clears this up i'm pressing on chekout, i just dont want to rush it since i don't know enough

i am. i have a bread oven i found on the garbage i use for reflow

just in case anyone is wondering and to avoid any conflict.
if i buy a qb for 75usd ill have to pay 40usd for shipping plus a 50%tax so
75+40+37.5=152.5usd
1 usd =16 ars
152.2usd = 2440ars
meanwell hlg-80h-c700a=1318ars
a grand total of 3658ars
or 234,875usd
just in case.

Good luck with the fiddly bits, I would hate to get all those SMDs on the pads without a robot to do it for me.

load a few podcasts and just go at it.

Just not feasible for anything other than micro. I guess if you're building like one board, but once you get down to covering larger spaces you'd be looking at placing 10k diodes by hand. At that point I will gladly pay a fabricator a small fee to save me the many hours it would take me to do it manually. I guess it's a matter of priorities and if you're living in Argentina, maybe you don't value your time at quite the same dollar per hour value I might.

ehmm actually i think i do, but i already do this sort of thing as a hobby(?
never at this scale though.
my growspace is 80cm x 80cm so 2 boards won't take me long. maybe a rainy sunday afternoon

With the 1050a driver your running them at 500ma each with the 2100ma you are running them at 1A each that is 2 boards per driver the fan in the room for the plants will be good to help cool the heat sink. The 3000k is fine for veg and flowerwould the 2x hlg-240-2100 drivers be better than the ones recommended by the webshop -> hlg-240-c1050a ?

thank you very much, have a nice yield xx
Greetings,
First post ever from a lurker needing to learn more than to speak. After following this thread bought 4 boards and slate 2's. I have questions but before that I must commend the NGL team. High response and follow through. Kudos.
I am trying to decide about drivers. Question 1; series Vs parallel. Many seem to wire in series. My concern is higher voltage when the same power can be achieved with lower voltage and higher current in parallel. Comments? Question 2; Meanwell A Vs B. Many recommendations are for the A but dimming strikes me as a desirable feature. Thoughts on the trade-offs?
Thanks to all.

so, hope i'm not bothering anyone, but does anyone have any opinion on running 10 parallel series of 10 LM561c and the chances of thermal runaway?

Dude - I watched one of your recent videos with a killer rig you built. I thought I remember you saying you were hitting the plants with too much light. Do you think this one might be a problem? I guess you can just raise the rig a few inches off the plant. I can't wait to see your new QB beast.

Actually they both will run the same or board 1050/2100. The only difference will be wiring. The 1050 you'll want to run 2 boards in series and the 2100 you'll run them in parallel.
I say go with the 1050 as if you add 2 boards later you won't have to worry about voltage bin as much as you can put one of the boards you have now in series with the future purchased board. Then run another parallel string the same way.
With 2100 they will all be in parallel so they would all need to match.

I like series wiring....... A type is dimmable as well. It has a built in dimming screw on top. B you have to add a remote dimmer (usually a potentiometer).
