You wouldn't have to drive 12 very hard for 10sq ft.
Any reason you are stuck on the number 12?
What are the dimensions of the floor area?

In the same space I run 8 less efficient cobs at 400 watts and it's a ton of light. 12 more efficient cobs run hard would nuke plants in 10sq ft. With cobs it is easy to find the point of to much light and over take it.
2 hlg-120 48a's will get you about 30 watts a sq/ft.
2 hlg-185-48a's will get you about 43 watts a sq/ft.
You can run any number of cobs on these. 9cobs would also work in your situation, 5 on one and 4 on the other to cover the corners. Both drivers would be very efficient.
If you really wanted to run 16 cobs you should also take a look at citizen 1212s, they are cheaper and the difference in efficiency is not as pronounced at this low level of wattage per cob.
In a grid, 3x3. The driver with 5 cobs covering the center, the driver with 4 cobs covering the corners.
And you are not overthinking, it's that people don't realize how efficient these are at low wattages.
Whick drivers do you have running those, great looking light by the way @topcat ...I have 9 CLU048-1212s in my 3x3View attachment 3868559

These particular drivers must be wired in parallel.
The stronger driver is close to too much light without perfect conditions, but you could always turn it down.
The weaker driver will put out over 1/3 more light than what I am (currently) running and I am experiencing vigorous growth.
Nice thats exactly what I want to build if I get another tent this same size. Thank you...HLG-120H-C1400B
