Sorry about the confusion. Obviously, I am not so knowledgeable about heat management in closed systems.

Didn't know what a "45CFM fart fan" was (before Googling), so mentioned the ~50 CFM of the fans I had in mind.

Though I'm not very familiar with Peltier devices, they can be had up to and probably above 226 watt ratings. My idea was to expel the heat from the bulb through ducting directly to the outside of the wooden box, then have some sort of cooling device working on the air coming into the box so that the temperature outside the box becomes less important and thus less harmful to maintaining cool temperatures. I don't care how hot it gets outside the wooden box.

I realized after posting that I was basically trying to reinvent a refrigeration/cooling system. In the interest of saving money, I am trying to find cheap means of cooling.

Essentially, I am trying to cool everything inside this wooden box as cheaply as possible. It's not that I'm disregarding suggestions, but throwing more out there to find a good (cheap) solution. Probably should have mentioned that earlier.
WaZ Reviewed by WaZ on . Cooling in small spaces A wooden box with dimensions 36"x20"x60" (25 cubic feet) sits inside a closed space measuring 37"x61"x93" (121 cubic feet). The closed space is used for storage and so actually has less room than that available. Is it possible to use a 400 watt HPS light with hood inside the wooden box and still maintain optimal temperatures? Preliminary tests suggest that temperatures easily exceed 100°F within the box, using 2-3 80mm fans each on intakes and outtakes. The light itself generates most of Rating: 5
