Craig-
If it were me, I would install a higher-than-normal little "ceiling" in there and inset a lampholder up and underneath. You can fit it with a 15 watt bulb for softly lighting the equipment and later, if you move, put glass shelves in there instead and say it's a curios thingie.

I know ALL 'dem deco-ratin' terms!
