Hello: I have a wall mount light fixture that uses 5 globe type bulbs. I have had the fixture for about 10 years, recently each time I replace a bulb - the new bulb burns out within a few hours. Only the two end bulbs remain lighted.
Can someone let me know what might be causing the 3 bulbs to keep burning out so quickly? I've been using both GE & Sylvania 40 watt incandescent bulbs.
