The "lightbox" consists of 72 ultra-thin LED lights set in strips and placed in a rabbet just beneath the rabbet for the obscure plate glass, thus making the whole assembly only 3/4" thick. The bottom is not closed since the lights cast nicely both up and down. The 6 watts of LED lighting are sufficient to illuminate a room. As far as the mounting goes, I thought why not use the Hungarian Shelves system just for a single shelf, aka sideboard. The beautiful wine glasses are by George Averbeck, Fire on the Mountain.
