Basically to light proof the box I ended up building a box within the box. The inner box is mostly poly-shield which is basically a reflective surface on styrofoam and all the seams are taped up with aluminum tape.
The intake is a long hole cut in the bottom of the inner box. The steralite box does not have a flat back it actualy dips in across the middle, so the hole backs up to this and the hole in the steralite box is cut maybe a half a foot up. So light has to make two right angle turns to get out. BTW that black peice you see in the pics is no longer there, instead I opted for a piece of black poster board that covers the entire floor.
The exhaust hole is cut for the fan I have in the top and it exists in the separation between the bottom half and the top. There is a opening in the back in the top section of the steralite box where the air is finally out. I use these carbon filter pads to further block light at the final exit and to take care of the smell.
Access to the inner box is another piece of poly-shield that can be removed. It is just cut to fit (needs to be pretty perfect or light will leak out).
The poly-shield and the steralite box by itself will not stop the light though (like i said the box was hard to lightproof
). A few coats of black paint to the inside of the box before you install the inner box would probably work... I had to resort to uglier methods though since my inner box was already installed when I figured this out.
Think that covers pretty much everything
