Beautiful, but does not work correctly consistently

It's a beautiful piece, but when I used the coiled bulbs that are more energy efficient than traditional bulbs the lamp acted up and did not work very well. Even now it sometimes does not respond very well, as far as going through the 3 different lighting levels but not turning off which is my intent. It has done this several times, and when I just leave it for a bit, then it will just eventually flash and go out.... not exactly the functional quality i desire.
