Lighting Idea for cube tank.

Luminarc reflector, single 175w mogul...

There's various ways to mount without drilling the ceiling, personally i like shelves installed to hang pendants from. One of the older style desklamps (think pixars bouncy one) can support a fair bit of weight. Many have mounted a single (or two) bent peices of electrical conduit. PVC piping same thing.

Dont forget a 24" fixture often will fit a 30" tank - legs often extend that extra 3" each side. Otherwise you could add a piece of square plastic tube on the top of the tanks rim to support the legs.
