I have a home office in my spare bedroom. My overhead light fixture, which just uses one 60W light bulb, blew on Monday. I replaced the light bulb a nd used it yesterday while working. Late last night, I went into my office and when I turned on the light, the new bulb blew. I left it until this m orning. It got me thinking on what could be causing two light bulbs to blo w with 48 hours. It's either the switch or the fixture.
I went out and bought a new wall switch (20A Leviton)and installed it, and replaced the blown lightbulb. It's working now, but for how long, I don't know.
Has anyone had any experience where a bad light switch would cause light bu lbs to blow only upon turn-on? Once the switch is turned on, it seems to w ork fine. I'm an electronic technician by trade, so I understand power concepts, but I haven't heard of a switch causing a spike above the normal AC voltage.
BTW, I checked the line voltage at the lightbulb and its 115 Vac.
