00:00Before the rise of structured grids, cities relied on open fires and iron wall torches.
00:06Fueled by pitch or animal fat, these primitive lights were smoky, highly flammable, and only lit during essential night events.
00:14The 19th century brought the first true urban lighting revolution, gas lamps.
00:21Distilled from coal and distributed through underground pipes, these fixtures required lamplighters to manually ignite them every single evening.
00:30With the commercialization of Edison's incandescent bulbs, electricity transformed the night.
00:39Carbon and tungsten filaments provided a safer, cleaner, and centralized light source that could be controlled from a single switch.
00:47By the late 20th century, high-pressure sodium and mercury vapour lamps dominated city avenues.
00:56Known for their distinct amber-orange glow, these gas discharge lamps offered unmatched energy efficiency and longevity for their time.
01:05Day, modern solid-state LED technology defines our streets.
01:10Cutting energy consumption by over 50%, these smart systems offer precise directional lighting, reduce light pollution, and integrate seamlessly into
01:21the digital infrastructure of tomorrow's cities.
