I would like to point out that a 2' x 2' cage has almost identical floor-space to that of a 41 quart tub that most people use for adult BP's. (571 square inches for the 41 quart vs 576 square inches for the 2' x 2') That said, I use full T8's for my adults, but you could house an adult in ½ of a T8 without any issues.
