I currently have a 19" cooltube with 6" duct work cooling and it works very well. My question is in my 2nd cabinet I have a 2nd 400w light and plan on putting a cooltube in place of the non-cooled reflector thats in there, can I put reducers on the cooltube to take it down to 4" as I already have 4" fans installed and wanted to know if that would be enough to cool it or does it have to be 6"?
