1000w Air Cooled Light, How Many Cfm?

[Tomcat]

Ok so my grow tent is 5x5x7 and I have a 1000w air cooled light....My question is, what size fan to blow air through the light. The room the tent is in, temps run in the mid 60's during the winter.

According to Phresh Filters calculator you need only about 208 cfms to exhaust your air in your 5'x5'x7'

Does that calculation take into account the wattage or just air exchange?

I really don't know, I'm pretty sure it's just a air exchange calculator.

Thanks for the assistance. That was for the air exchange in the actual room. Still trying to figure out what size fan I should run for cooling the actual light.

Ahh ok man I got you. I run about 1300 cfm in 4 1k hoods and it keeps them cool to the touch.

1 of these should cool your 1k hood since the air that's flowing thru it is in the 60's. I run 1 of these in each hood plus a 10'' can fan 1050cfm to cool my 11'x13'x16' room and the air that flows thru the hoods is around 70 degrees
