Im running into issues with heat in my tent when i run both my unit farm UFS3000 lights. I have 2 autos that just started any clue if one light would be sufficient for this grow to help control temps. Running 85-87 with 2 lights 80-81 with 1 light.

How many watts? How is the spread of 1 light?
Is there an AC in the room the tent is in? Taking in air from outside? Local temps high?

I would ass a fan pointing directly at the driver on each light to cool them down. Cool down the light, you will cool down your tent.

Airflow is the best way to fight temps. Plants will do fine at 85-87F. Not really going to run into problems until temps get above 90F.

I looked your light up and one light is 200 actual watts and a flower cover average of 2x2 so one light for one plant

Yep just seen that apparently one can work with a 3x3 max.
The room its in has attic access so it runs hotter then any room in the house i do have central ac. I ran exhaust ductwork from the ac vent to one if the bottom intake vents when the ac is running its staying around 81 when its not running 86-87 range i notice though when i run ductwork directly from ac vent to tent intake port that it lowers humidity around 40%

Hang a damp towel in your tent it will raise humidity
Will give that a go. I thought about a cool mist humidifier to combat the humidity and maybe help with temps. Right now i have a cheap clip on fan inside but tomorrow my 2 cloudray ac infinity oscillating fans will be here. Not 100% sure where to position them in the tent for maximum results. Thanks

Make sure they are blowing air thru the plants

Are the lights dimmable? 400w is kinda overkill in a 2x4. 300w is pushing it, but doable.

Your temperatures are just fine.
Working on trying to be cooler come flowering time
Ya i get that but honestly i dont think 85-87 is a big deal even in flower. Been over 90 every day here and my outside plants are loving it. Have one photo in the tent week three after 12/12 running at about 85 and its looking good ill post a picture. How many fans are you running in your tent? And how big is your tent with your two lights?
Running a 4x2 with a AC inifinty Cloudline t6 with 2 cloudray 10 speed ac inifinty oscillating fans problem is its a atic access room i struggle to keep cool.

I keep another fan on one of my bottom flap openings that will pull a little cooler room air and disperse it through my 4x2. Also have my infinity set to run at 100 percent when my tent reaches 85. Hopefully your room temp is lower than whats happening inside your grow. Good luck brother, i think you will be ok.
Thanks sir ill try and add a fan to pull in more air through the intake aswell

Is the driver outside of the tent? A driver can add a couple of degrees.
Because of the lights significant decrease in PPFD beyond 24 x24" I would run both lights. Moving as much air as you can will help offset higher temps.
Driver is outside on top of the tent with the exhaust from the ac infinity inline fan blowing on it to keep it cool
