LED may be an interesting option to dose light more finely. Not sure what happens to color temperature when one modulates intensity.
The light-fall-off will still be the same for a top placement, but a strip of LEDs in one or two corners may work. Would still need to be water proofed, and has the same access issues (though LEDs last longer).
Interesting thoughts ...
Plexiglass is certainly easy to drill, but not sure about the visual quality. May have to look at some particular examples. Plexi also scratches more easily.
