The flashlight has evolved significantly since its invention in the late 19th century. Early models used incandescent bulbs powered by bulky batteries, which limited their portability and efficiency. The introduction of LED technology in the late 20th century drastically improved brightness, energy efficiency, and battery life, leading to compact designs. Today, flashlights are often equipped with features like rechargeable batteries, multiple brightness settings, and durable materials, making them more versatile and user-friendly.
