If you check out the pic in my post right above, you can see a fan cut into the right side of the box. That's an 80 CFM fan pulling air out of the box. I also cut several vent holes in the top of the box to allow a passive air intake. The temp inside the box is still around 80 degrees with only the 20w CFL, probably because the box is in my closet and is covered with a blanket. I am kinda stuck here because i can't think of a way to add more light without making the temp inside the closet/box too high and still keep the stealthiness i need.

Any ideas?
