It's probably not as reflective as you think. Brushed aluminum won't be as refelctive as mylar or flat white paint.

My choice would be 32 gallon, painted white on the inside or black/white plastic.
4 CFL's mounted to a base that can be suspended by chains and raised and lowered top down.
I would drill some vent holes in the top and sides and drainage holes in the bottom.
One small desk fan inside the can mounted to the top blowing indirectly on the plants.

You can however, get more square footage with two rubbermaid containers put top to top or a rubbermaid deck box and grow some bonsai style plants.

Good luck either way.
