Diy question

Hey everyone.
Just started growing indoor this year and began with what I had laying around which was 3 florescent T8 fixures for 6 tubes total.

After much reading I have decided to build my own quantum board.

I'm not entirely confident I fully understand circuit design so I'll post up my plan and hopefully someone who knows more can chime in.
My components are as follows.
Samsung 561c 3000k
Meanwell lld1500h driver
Meanwell ‎LRS-150F-48 power supply.

Here is where I'm not so sure
I plan to wire it in series parallel
So the two lld1500h will be wired in parallel from the power supply.
Then each driver will have 2 parallel strings with 10 LEDs in series. Totaling 40 lights.

Also is this right?
The drivers are 1500 ma so with a forward voltage of 2.75 each driver will be 27.5 volts and the current will be 75MA per light?
Is this right wrong close?

You are wrong, LDDs are constant current so each string in parallel will get 750mA. You can wire them in series direct to the LRS but you need at least 16LEDs in series and a multimeter to set the appropriate Voltage according to the selected Current.

Ya 2 strings per lld1500h is 750 ma per string.
Do you see any other issues I've overlooked?

May I know your proyect with these LEDs?
2.8V@75mA=0.21W x 40=8.4W
Basically you can drive them with a 12V 1A power supply and a resistor to limit the current.

Trying to copy the quantum board. I have more time on my hands than I do money.
