Let's start with the lights themselves. Are you talking 2400 fake watts from a red/blue panel you found on Amazon or are you talking 2400 watts at the wall with a quality white led light? If you're talking true wattage, then almost 50 watts per square foot is a bit intense. Using COB leds, I flower between 20-40 w/sf, with 30 being my sweet spot.
Another thing is room temp under white led will be higher, my room stays between 79*-86*f with or without CO2. Because of this, I have not had to run my Mini spit in a couple years. Just 2 8" Hyperfans for intake and exhaust hooked to a temp/humidity controller (turns on at either 86*f or 60%rh). For winter a dehu for heat and CO2 because the fans seldom turn on.
