i think you will be better off running a daisy chain type setup so that it goes from fan to light to light to light to exhaust . in your setup airflow to the last 2 lights will be minimal because the air will flow thru the path of least resistance.
by daisy chaining them the air has to flow thru them.
in your setup it doesnt have to and probably wont

yep he is right if you would turn the lamps 90º angle facing them with the length towards the length of the room then put 1 extractor where the air has to leave

yup that works .. you can face your lights the way you had them faced in the first pic as well if that gives you better coverage but the bends in the ducting will restrict some airflow. if you choose to turn the lights make sure you use hard 90s so that the aiflow is restricted as little as possible.. otherwise the drawing you have here will work perfectly

Now you got 2 problems,
1.the carbon filter has to be included in the duct line otherwise has not much use
(there should only be 1 intake and 1 outtake)
2.Plants need the FRESH air not your lights all you want to do is suck the hot air away from your lights not cool them off so the ac will still be necesary in a 3000w growroom or temps will go skyhigh

yea, i forgot to include that in the drawing, it will be in a very warm place to begin with, so i might go with a 5k btu or 12k btu, depending on hot hot the total space is

his carbon filter setup works .. hes pushing air out of the grow room thru the filter and into the outside air.
and looks like the AC was providing the intake air ... musta dropped that in the last pic but yes you will want fresh intake air to replace the air pushed out by the fan / filter combo. you can do this via passive intake ... ie: a hole with a light trap to allow fresh air in and not light ... or you can do it by forcing cold air in via the AC you showed in previous pics

and about elec bill, its not about how much it costs, doesnt really matter with what you get out of it, its more about your elec company seeing a massive rise in electrycity wich will bring on an investigation
3000w x 30 days x 18 hours = 1620 KW
3000w x 60 days x 12 hours = 2160 KW

My monthly electricity bill (growroom included doesnt go higher then 700 KW/ motnh)
and you got more then 1400KW with just lights not including fans/extractors/tv/fridge...etc

works ? yea it works its just more work putting 2 ventilations instead of 1 that does the same job, putting the Carbon filter just before air gets sucked through lights will get rid of smell then extract all heat of lights.

Just trying to make it easier

i really cant elaborate on how i will get around this, but i wont be drawing attetntion with the amount of power already in use at this location, whatever i add on wont even be noticed
