“They don’t make ’em like they used to,” as the idiom goes. So it would seem for the Centennial Light. An astonishing, record-setting 115 years after someone first flipped it on, this light bulb is still faintly shining in a fire station in Livermore, California. (You can see it for yourself on a webcam that refreshes every 30 seconds.)For the multiple generations of us who have since swapped out more burned-out light bulbs than we can remember, the Centennial Bulb’s longevity must seem like a slap in the face. Surely, if an incandescent bulb made with 19th Century technology can last so long, why not new-fangled, 20th and even 21st Century bulbs?
