    At a fire station in Livermore, California, there is a four-watt carbon filament lightbulb that has been burning around the clock since 1901. That’s over one million hours! The Guiness Book of World Records, Ripley’s Believe it Or Not, and General Electric have all confirmed that this is the longest-living lightbulb in history.
