You can use this technique to build different kind of lamps, here I show three types:
1 and 2 are multy purpose lamps. For a Desk/table lamp, put it over a energy saving lamp, or hang it on a roof lamp.
3- Ideal for roof lamp or to hang it on a stick with a little tea candle inside.
4 ... You got it, and you can make infinite variations on this... Let's lamp!
