Hi, I have an old piece of stained glass (from a larger window) that I want to put into a coffee table with a light underneath. I don't have a particular table yet, but I know I want the light not to be very bright, not strong, just enough to make the point and I don't know how to set it up. Would an LED light be too strong and/or focused at one point (thinking of using one because it would last a long time) or should I use something else? Is there any way to do it without electric cords being involved? Basically, anyone have a clue where to start? Thank you!
