Bulb socket, switch and cables are well made. Cables and switches are slightly transparent. The lamp can be operated with a lamp up to 25 watts. But I recommend a LED lamp with significantly less power. Negative falls on the bottom of the lamp. It consists of a piece of soft plastic, which can be glued to the bottom of the bottom open ball. The floor is self-adhesive. But then you will not come to the light, if that is to be changed once or needs. However, the soil must not be glued. You can leave glue the protective film on the floor and then put the ball just loose on the floor.
