I installed a cieling light fixture by Aztec and everything was fine with 3 100 watt bulbs that it is rated for. Then a couple of days ago I decided to try florecent bulbs that give 127 watts of light using only 26 watts each. One bulb blinked when the light was turned off at the switch. One bulb strobed if it was in one outlet and not the other. Today two of the bulbs blew out and there was a strong burn smell coming from the mechanism in the bulb. I turned of the light and took off the fixture and there seems to be nothing different about the wiring although it is old. There is no grounding wire and the wiring junction is not in a box. I installed the fixture using a joist and brought the wires down and tucked through a metal plate that I installed. My question is this: Could there be a short in the wiring to cause two of the bulbs to blow or more likely is it the fixture? Not sure where to go with this and I would like to have it together for a dinner party Thursday night.
Any suggestions would be appreciated.
