So I figured Ide share this . This is the company most people are using to buy from overseas and resell led QB288 parts heatsinks and panels here in the usa on places like ebay. I know they are 100% legit and have been talking to them for the past week. Shipping is about 40$ . You can buy a pretty awesome setup from them dirt cheap.
Im ordering some 4000k panels with cree red 660nm chips, uv , IR

Great 
My current setup now is 11 x EB.gen2 and XLG-150-L-AB
So, I have 26 x SMJD-3618072C-XXN1 00D30E038ALL from Seoul Semiconductors Inc.
And 2 x MeanWell HLG-240H-36A
I have a few concerns I hope I can get some help with
Bought the drivers secondhand ages go, so would like to make sure that the VOadj and IoAdj buttons are set correct, but have no idea how to mesure it with a multi-meter.
Also, the wiring… Parallel, or Series? I tried to figure it out, but the darned drivers have driver Mix mode (CV+CC) lol, so confusing…
Wire thickness is also something I haven’t found an answer yet, but I guess same dimension as Bridgelux’s? Found wire meant for wired doorbell, which is 0,7mm thick.
All help is much obliged!

@Kayoes for your driver all you have to do is wire those strips in parallel as those 72C’s voltage range is 33-35.4w with a nominal of 34.2v
And watch some youtube vids of voltage and amperage measurements, basic of it is voltage is measured across the whole circuit or the part you want to measure so in your case the positive side and the negative side, as for amperage you have to measure inline with the circuit as int he multimeter becomes part of the circuit say the + leads goes tot he multimeter and the common lead from it goes to the + side of the strips, no bypass, but CAUTION read up a bit first and watch soem vids and check your multimeter as unless it has a higher amp reading circuit you may not be able to measure total amps as alot of cheaper meters only measure to say 200-400mA, where as others have 10A capabilities.
Saying that if you have a wall watt meter you can just set your Io screw with that and dial in to the wattage you want as at max your still a little under nominal amperage wise for each strip when you have 13 in parallel off a driver, but note you can over drive those drivers, still should be alright though,
As for how those drivers work they are constant current and work off the Io screw setting as the main point and if the Vo screw is turned all the way up, its only once you screw down the Vo screw to where your specified circuit voltage with that screw hits a point that it goes lower that your Io screw current setting that it goes into Constant voltage mode, short of it Vo screw may not need to be touched and if it does just turn it up so your just running off the Io current settings.

Yes, Meijiu as well . I personally do not have first hand experience with them but others do and ive seen good products come from Meijiu. They seem like there a great business to work with.

Hey @Kayoes,
The HLG-240H-36A has a voltage adjust range of 33.5 to 38.5 so that is well matched. The maximum current is 6.7A meaning the driver can handle 8 strips at 100%. Personally, with those parts, I’d build 2 lights of 7 strips ea. That would run the drivers at 87% and produce 210W
What size of light(s) are you going for?
Cheers

thats 840ma “max” running 7 strips would go past that potentially meaning letting the smoke out.
again the 13 strips per driver like @Kayoes already has will allow him to run those drivers at max with the strips being at almost nominal levels , not maxed out or past them, the overdrive range on them isn’t as much as other strips, so id say better to be safe whether nominal at 13 strips or over driven with 10 or whatever, but playing within the comfort zone.

I see what you are saying, fewer strips per driver gives the potential to overdrive the strips. My concern was potentially running the drivers at 100% for long period of time.
I was assuming adjusting the max current to match the number of strips. I should have stipulated that

Guys, you are pure awezome.
Celebrated my 41’ today, and made sure my brother in law brought his multimeeter.
Kinda proud of myself, making a list before rushing into stuff 
We measured that the drivers were set to 39,5V.
I’m still educating myself,within the tech area, which seem trivial, but my brain does the complexity stunt as usual 
Plan as follows:
60cm x 120cm frame with 13 x Soul + 11 x Bridhelux Gen2, both 4k
I’m actually thinking of putting this into my tent which is 100cm in hight
So, dimming are the next step after parallel connection of the new led’s.
Final step is my 8 x 8 feet tent.

presume the bridgelux and seoul strips will be separate circuits and drivers, as for dimming you’ll be able to dim with those Io screw

This project is going as well as ever could hope. Thanks everybody. I will be borrowing an apogee par meter to have some fun.

Thats a beauty. Sure to blind! Lol
How are you attaching those strips? (I’m using #4 sm screws)
Here’s my latest @ReikoX inspired flyweight. Using thermal tape.

Cool little light! I’m actually using rivets. It never would have occurred to me if not for some posts upthread.

So I grabbed two more quantum boards LM301H with UV & IR . But this time I grabbed 150H 54V mean well supplies.
Im going to truly push these to the edge . I wish I had a Par meter.

Hey, so I got this setup and it worked great for a buddy’s 2x2 cabinet. Thing is, I ordered two sets so I’ve got nine strips and a driver sitting around waiting to grow some plants.
I want to put some of them in a small cab that’s 16"×24" so I don’t want to use them all since that seems like overkill. I was thinking that 5 strips would fill the space fine but I think 6 is easier to wire up.
So the strips have an operating voltage of about 33v, and the driver can range from 60v to 107v. I was thinking I would wire 2 strips in series, 3 groups of these in parallel, and use the trim screw on my driver to drop my output volta e to 66v. That seems to be on spec to me but I’m not sure if this means I’ll lose all my range on my dimmer knob… if I’m only running 6 volts above the drivers minimum output will I still get any range out of my dimmer?
If anyone knows this or can reality check my approach here that would be most appreciated. I’m also looking to use the remaining 3 strips in a small mom and clone setup and need to find a cheap little driver to run those three strips on their own.
Thanks in advance!

Hah, first to respond to myself here! 
I’m looking at this driver for the remaining 3 strips, it oughtta work if I wire the three in parallel and just adjust the voltage down to 33v, right?

Either or the reverse of 3 in series and 2 parallel chains which would allow the option to over drive them a little if desired, but 3 parallel chains would be the safer bet is say one chain happened to fail then the others wouldn’t get over driven as harshly. Also the trim screw just sets the current not the voltage, the voltage will only be what the circuit pulls from the driver. Also if you have the AB style driver the dimmer output also just limits the current
And that XLG-75H or and L would work just fine for the other three strips

Thank you OG community so much 
The wiring isn’t finished, still needs a bit of work. Everything else is great!

Ok!
I’ve been mulling over a lighting upgrade for my cabinet for a while, get rid of my Frankenstein lighting stack. I feel like I’m finally closing in on things here.
I run vertical in this cabinet, so I’ll be building a vertically hung cylinder or hexagon of Bridgelux Eb3 slim strips, 24 of the BXEB-L0590U-35E1500-C-C3.
They are nominally rated at 19.1v and 700ma, which would put them at 13.37W per strip. 24 of them would pull 321 watts at those levels, and produce 186lm/w.
The data sheet lists a viewable angle of 120°, if I place 24 edge to edge in a cylinder that’s one strip every 15°, so I think that any single spot on my canopy should be receiving direct illumination from 8 strips at a time.
13.4w per strip, 186lm/w, 8 strips hitting a point on the wall with a combined 20000 lumens. Ah, but lumens are not a measurement of what hits the surface, and so this handy calculator gives us an idea of how many lux our girls will bask in.
https://www.bannerengineering.com/za/en/company/expert-insights/lux-lumens-calculator.html#
Ok! So at about 11" away from the source my babies will be getting thumped with 70,000 lux! Hah! 11" eh? That’s nearly all the way to the wall! So yeah, I’m thinking these are gonna turn out enough photons to really kick things up in there. Here’s the real kicker though, over my 24 square feet of canopy I’m technically only running 13.4w/ft2! But of course, I’m growing plants up the walls, not the surface of the walls themselves.
More than likely I’ll be dimming it a bit! 
At least, that’s my thinking at the moment. So much of the info out there is all geared towards flat canopies that it’s been a bit of work to get my head wrapped around. I’ve done a lot of second guessing but I’m feeling pretty certain that this is making some kind of crazy sense finally.
So now to pick a driver! I’ve got a few candidates in mind, but I haven’t even looked at the notion of over driving things at all yet, so I’d be curious what others have to say. How much nonsense overkill could I crank out of this rig?
As always, I appreciate all input from you fine OG folks! So whaddya think?
