I have a 1000 watt air cooled light attached to a 220cfm fan. The fan is connect to a duct ---> to light----> to duct that travels about 8 feet to the window so it can suck in colder outside air. My questions are is it worth it to have long ducting to connect your air cooled fan to the window (i heard the longer the ducting, the lower the cfm)? And does higher cfm mean better air cooling (like 220cfm vs 440cfm)?
