This is cheap and easy. I bought this japanese paper lamp from IKEA for about RM19.90(USD5.50).
You can choose your type of cord or the voltage of the bulb.

Step 1: A Piece of Big Brick

You choose a piece of big brick that is heavy, so that it will not fall when you shaft the copper or any bendable rod for the lamp.

Step 2: Finding the Right Hole to the Brick

Drill a hole in to the brick, make sure the drill head size is the same size of the rod.
Or you may find your rod fitting into a hole that is too big, that wouldn't stand straight.

Step 3: Install the Lamp & Bulb

Make sure you get the right bulb and cable. You can try the bulb if it is lighting up before you pay and walk out from ikea.

Step 4: Hang the Lamp & Tidy the The Cable

You can tidy up the cable with some cable tie, as you can see my cable tie is still attached on to the rod while the lamp is hung up there.

Step 5: Chillout, Kick Back & Enjoy

You can chillout, do read some or whatever under you new light. Make sure you get the right warm white bulb instead the the white bulb. It's yellowish when it is turned on.
