Hopefully someone can help me out. I have a large wood display case, it is tall with several glass shelves, I have a lighting issue. Since I use colored felt to display my K&c stuff, on each shelf, the one light at the top can't penetrate down to the lower shelves, so the lighting gets dimmer and dimmer as you go down. Does anybody make small battery operated lighting that I could add to each shelf, I am trying to get away from having to drill holes and mess with cords and all of that. I thought maybe some small battery operated lights that you could just set on each shelf to turn on or turn off when you want. If anybody knows of anything like it, please let me know.
