How a Light Bulb Has Stayed Illuminated for More than a Hundred Years


the finest light bulbs tend to burn out at the most inconvenient times. However, here is one bulb that challenges those expectations, a marvel of illumination. This bulb has been lit for more than a century. Picture that it was powered on long before the Titanic embarked on its journey, and it has remained lit ever since. Well… nearly ever since.

Located in the fire station of Livermore, California, this legendary light bulb first illuminated in 1901. Believe it or not, it has illuminated the paths of six generations of firefighters with its comforting amber light. This originally 60-watt centenarian was switched off only once to relocate it to a different fire station building and a handful of times for upkeep.
