Downsize from 1000w to 600w?

Ive got an 8x7 room with 4 Magnum xxxl 6" hoods.. Soiless mix, SCROG. CO2, Sealed room.

2 Bulbs are 1000w and 2 are 600w..

3 Fans Moving Air through the hoods, and a 9000BTU A/C

Room still gets too hot, it hits 90 if i dont leave the door open for a bit. Should i Sell my 1000wers and just run them all with 600's.

is 1000w going to a 3.5' x 3' Screen overkill?

I personally would run a 600 watt over a 1000 watt any day you are saving yourself money just from there however, 600 watts are still plenty hot your problem may lye more in simply the heat itself using that much wattage in one room one could expect to see temperatures in the 90s be careful on the choice you pick to be your problem solver unless money is no issue
