Street Lamp

The tall pole that lights up city sidewalks after dark/Everyday Objects

Modern street lamps use LED or high-pressure sodium fixtures mounted on steel or aluminum poles. A typical residential street light stands about 6 to 9 m tall, while highway lights can reach 15 m. LED street lights use about 40 to 60% less energy than older sodium lamps.
