What lighting method became common in the 19th century?

The lighting method that became common in the 19th century is gas lighting. This innovation represented a significant advancement in theatrical lighting technology, providing a more reliable and brighter source of light compared to previous methods. Gas lighting allowed for better control over the intensity and direction of light on stage, enabling more dynamic and visually striking productions.

Before gas lighting, theatres primarily relied on candles or oil lamps, which were less efficient and posed more safety risks. While candles created a warm, atmospheric glow, their limited brightness and flickering nature could not meet the growing demands of theatrical performances. Oil lamps offered slightly improved illumination but still fell short of the capabilities that gas lighting provided.

LED lighting, on the other hand, is a modern technology that emerged well after the 19th century and has only gained popularity in recent decades due to its energy efficiency and versatility. Hence, gas lighting stands out as the pivotal lighting method that reshaped the theatre landscape during the 19th century, enabling more elaborate and intricate stage designs and lighting effects.
