The lamp is in 10 minutes. built. For this I had to each other only a few pieces of pipe and the shield screw. All without tools. I operate the lamp with a Philips 25226225 EcoClassic 30 E27 A60 Brilliant halogen light 105W bulb-shaped, clear. This gives a nice floodlight to the ceiling. Negative is the cable, which is guided along the outside and looks like something bammelig.
