Out in Livermore, California, one particular light bulb has seen more wars and events than anyone alive today. It’s been burning for 107 years and was manufactured by the now-defunct Shelby Electric Company. The lightbulb now has a home inside Livermore Fire Company’s Station No. 6., probably next to one of those cameras it powers.
Unlike light bulbs today, this particular bulb is said to have a perfect seal that allows no air to enter it. This keeps the bulb burning continuously for 24-hours a day and it emits no heat, just like that glow-in-the-dark doorknob you bought the other day.
