Would using a non air-cooled reflector w/ a inline duct as exhaust fan raise temps?

Greetings RIU!

I am shopping for a HPS/MH setup, and I have a question about reflectors. After doing some looking, it seems that a reflector that is not air-cooled can be much larger in diameter, thus spreading the light more evenly.

How much would a 1000W light with a non air-cooled reflector raise the temperature in a room that is 6 feet deep, 4 1/2 feet wide, and almost 7 feet tall, IF I had a inline duct fan attached to a carbon filter exhausting out of the room?

Any replies will be much appreciated!

Not knowing how the ventilation system is set up, my starting guess would be a increase of 10 degrees over ambient temps.

I will have a 6" 43​5 CFM​ Blow​er with a carbon filter attached to the ceiling, venting out to the next room.
It will be placed near the reflector.

Only thing is you wont be able to bring the light down as close to the plants because of all the radiant heat coming off the light. You would be suprised at how large the air cooled reflectors can be. My reflector is rated for an 8X8 room with supplemental lighting at 10X10.
