I guess my main worry was if running 1 fan to cool all lights and that fan craps out on me then I am baking whatever is under the lights!!

SN you say 700cfm on an 8" duct, are you running a vortex type fan or?? also I found a cfm calculator on 1 of the hydro sites and says for my size room I need to have aprox 380 cfm for an exhaust fan (which will be sep from the light fan) this sound about right?? Sorry if some of these questions are redundant I just dont want to buy things more than once hehe :thumbsup:

Originally I had thought of using 2 1000w lights but have Rating: 5
