The Chandelier is hung!

Sorry for the poor quality of photos. Since my camera is broken I'm using an old one that is only 2 mega pixels and it doesn't work very well. This is the chandelier that I bought at a garage sale awhile back for $20. Click here to see that post. A couple weeks ago my ex-husband came over to help me hang the chandelier. We got it up and I flicked the switch and we heard a loud POP! IT SCARED ME
