Today I am mounting the same geometry on an aluminum frame; 1/8" TH x 1" wide X 24" x 8 strips for a 2x2 tent. I will post pics afterwards and you may understand what I am doing better than.

Is the cookie sheet for demo or is that a panel? If you were just showing them setup and thats not a actual panel you built my bad lol i thought you were going to fire a heatsink and led strips on a cookie sheet and grow with i didnt get it

I greatly appreciate you putting this information up. Thank you for taking the time to write it up so clearly.

build a Quantum Board Killer

Tired of waiting for a Quantum Board ? No problem.
First. The science behind the Quantum Board is they use 38 diodes wired in series with 8 strings, this is called 38S8P or 38 diodes wired in series and 8 strings of wired in parallel.

Second. Flexible Samsung strips are $6/m average order 40 meters. 1 meter is made up of 10 segments of 7 diodes each. Working with strips segments I would recommend using 6 segments for each string. However to compact the size I would recommend cutting the 6 segments in half into 3 segments each and rewire them in series making them 12” long by two strips wide. Do this for all 8 strips. A 40 meter reel of Samsung LM561C S6 bin diodes holds 10 segments per meter x 40 meters or 400 segments. It takes 48 segments to make one board. A reel of 40 meters might run $300 shipping included. For $300 you can build 8 Quantum Boards.

Third. I decided to use 3000k 90cri and 5000k 80cri for all of my builds with Samsung flexible strips. So I cut my 8 segments into three segments each and mixed the spectrum on each column. I provided some pictures to show you how I applied the strips to a Cookie Sheet and connected it to a HLG-185H-C1400B meanwell driver and I have a 150w GrowGreen Flexible Strip Board.

Parts:
1. 24 segments of 3500k 90cri cut into 12” lengths at 3 segments each. $15
2. 24 segments of 5000k 80cri cut into 12” lengths at 3 segments each. $15
3. 22 gauge wire to connect series strings and parallel strings. $ 5
4. 1 Meanwell HLG-185H-C1400B led driver (reuse) $58
5. 1. Cooikie sheet 12” x 13” flat from hardware store $12
Total cost $105

Samsung strips can be gotten at Mufue Technology at Alibaba ask for Roget
Enjoy your DIY Quantum Boards

Couple of quick questions, if you get the time....

How are you wiring, just soldering or is there a wire connect for these bad girls?

Bin on the diodes S6's...or 5's? You said 200ma which 6's are capable, but just double checking...

Just bought a bunch of 3k 80Cri Bridgelux strips and love them, but wanted something like 3k 90CRI! Wish I would have waited lol......are there any options like 2700K?

Thanks, good build. HeatsinkUSA has 1" wide strips at $.16 a foot. Would pair nicely with these flexible strips....

They make no solder connections, but it is easy enough to solder with wire if you have any skills.

bin is S6, latest available.

all options are available that Samsung offers just ask Roget.

I use light flat aluminum and of course I also used a cookie sheet that does not get hot. flexible solutions easy

90 CRI is not available as S6 bin though.
also when i contacted Roget about constant current strips she sent me images of 5m constant voltage strips (without current limiting resistors, 24v).
then Roget said they were both constant current AND constant voltage. i am completely confused.
which one to get?

I went with the 70LED/m, it is very confusing though with all the different options. Roget is right, you can run these as constant current or constant voltage, depends on the driver you choose.
