Or just drop the light down on a pole. Or again even better take a peice of Melamine or another wood, Cut it to size, put it inside, and make it 2, 2ft high vivs, or maybe storage below.

Anyway, no matter what if you can get it cheap, then im sure you can find a use for it, May take a few modifications, but definitally not difficult.

Edit: I have a 5x2x2 with a 5x2x2 stand, looking at it now, a tad tall all together, but maybe make it 2.5 ft with a 1.5ft of storage, or a 5x2x2 will work great. Gives some good space for my dragon.
