I got a question here about a ceiling light fixture in my son's room. Whenever, I put a light bulb in it, it blows it out immediately. It is a 3 light bulb fixture. I am using the right light bulb and the right walts, is there a possible short in the fixture or maybe, a short in the wiring? Is their a way for me to tell? My husband put this fixture in about 12 years ago. Thanks. Cookie
