inventions · electricity · everyday tech

Light from power. An electric light is a device that turns electricity into light. It's the most common kind of artificial lighting in the world.

Snug in the socket. Lamps have a base made of ceramic, metal, glass, or plastic that holds them firmly in a light fixture's socket.

Twist or click. Bulbs connect in different ways, like a screw-thread base, two metal pins, metal caps, or a bayonet mount that locks into place.

Goodbye darkness. Before electric lights, people relied on candles and oil lamps. Now a simple switch can fill a whole room with light.
