A century-old tungsten filament lightbulb discovered in a time capsule in GE's archives still works when plugged into a modern socket. The bulb was found, along with four others, in an Edison-era cache preserved at GE's NELA Park building in East Cleveland, OH.

Although the folks at GE didn't ramp up the antique bulb past 60 volts for fear of burning it out, it was still able to give off a visible glow once it had been properly cleaned.

The bulb is an impressive piece of technology in its own right, but also a reminder of how far lighting standards have come in the past 100 years. NELA Park, where the bulb was found, is also the site where GE engineers created modern light sources like halogen bulbs and LEDs.
