Recently Opened Time Capsule Contains 100 Year-Old Lightbulbs That Still Work


100-year-old time capsule

The tungsten filament bulbs needed a little cleaning after being removed from their temporary tomb, but once connected to a socket and slowly powered up to 60-volts, the majority of them slowly came to life. They’re obviously not as bright as modern bulbs which use more efficient filaments, but claiming a 100 year shelf life would be impressive even today. [GE via BoingBoing]
