Hi everyone, So i have an oak color Billy Bookcase, where i am using 3 shelves for my Transformers collection. I recently bought 2 glass shelves, so replaced the top and middle wood shelve with the glass, and it is indeed much better now that light from the room can get everywhere. But i need a light system for these shelves, either some on top, or on each level. Pls help me on what to put, i need some ideas. I am not an electrician, and it has to be able to plug into the wall. I can drill holes in the wood part of the shelves, and i want to be able to still move the glass shelves one up or down hole.
