Apparently a normal light source, the Milky Way Chandelier is made out of 14 empty milk gallons (washed), 1 hula hoop (cover removed), 1 set of 5 watt holiday lights, 28 screws, 4 eyelets, 1 clothesline, as explained here.

The view from beneath is particularly interesting and it confirms that the chandelier is not only ingenious, but also good looking.
