I have seen alot around about hoods with glass bottoms and fans circulating air through the hood to keep the heat from warming the room up, i think thats the point please correct me if i'm wrong.
My question is this, how do you determine the size of fan you need to keep the light cool. More specifically if you wanted to use a 400 watt HID in a small cabnet with an ambient temperature in the 80-90's, how much air circulation would you need to mitigate the effect of the lamp.
