Arc Lamps

Definition

Arc lamps are a type of electric light that produces illumination by creating an electric arc between two electrodes. This technology marked a significant advancement in lighting, particularly in urban settings, where it provided brighter and more efficient illumination compared to gas lamps. The introduction of arc lamps transformed city landscapes by enabling longer hours of public activity and enhancing safety through improved visibility.

5 Must Know Facts For Your Next Test

1. Arc lamps were first introduced in the early 19th century and gained popularity for their ability to produce intense light output, which was ideal for illuminating large public spaces.
2. The use of arc lamps in cities began to rise significantly in the late 1800s, marking a pivotal shift from gas-powered lighting systems.
