Re-activateBut one lightbulb—an incandescent bulb at that—has those young whippersnappers beat by decades. Commonly referred to as the Centennial Bulb (shown), this 4-watt incandescent lightbulb made by the Shelby Electric Company has been burning almost continuously in Livermore, California, since 1901, serving as a night-light in different firehouses in the Northern California city. Read more about this indefatigable incandescent and check out the bulb's webcam. I wonder whether there's a line in Las Vegas for when the light will finally expire.
You're unlikely to get anywhere near that longevity out of a standard incandescent lightbulb. In fact, a 15-watt incandescents I installed yesterday has a life expectancy of 2,000 hours. (I can't find compact fluorescent lightbulbs that will fit the fixture.)
