DIY with Quantum Boards

8-12 boards 4 240 drivers. I like the idea of 3 boards per 240 driver. Use HLG-240-2100A and you will achieve around 290+ watts wide open per driver/3 board combo. This will give you a great amount of light for flowering in that space.
Hell I was thinking of using Elg-240-54-d2 driver in veg and dim when needed

I have tested B type and it pulls around 170-180 watts at 120 vac. You can't run them in series on that driver. It is only 143 volt. A TYPE will do better.
So what is your preference when runnung driver's, A or B, i am currently running 8 3590's and use two drivers so i went with eternal dimmer. Now im getting 4 quantum's with one driver, wouldnt it make sense to simply get an internal?

A type generally will give you more power so i like them better if you have access to the driver.

Sensor used here is an old SQ120. Will make new charts in 2-3 weeks with Lighting Passport Spectrometer

12 inches and 18 inches. No optics on boards.

Tent was 2x2.5 and measurement was taken only in 2x2
what do you have to run to get the same output in a 4x4? at the same heights?
