Final answer:
Lighting technology has come a long way since the invention of the incandescent light bulb by Thomas Edison in 1879. Innovations like LED lighting fixtures have made lighting more efficient and convenient.
Step-by-step explanation:
Lighting technology has advanced significantly over time, with the invention of the incandescent light bulb by Thomas Edison in 1879 being a major milestone. This invention revolutionized how lower- and middle-class Americans lived, as electric power became readily available in cities. The development of AC (alternating current) system by Nikola Tesla further extended the reach of electric power, allowing urban areas to cover greater areas. Today, advancements like LED lighting fixtures have made lighting more efficient and convenient, with LED lights being even more efficient and longer-lasting than traditional incandescent or fluorescent lights.
