Lighting has been a crucial aspect of human civilization, providing not only illumination but also contributing to the aesthetic and ambiance of spaces. From the early days of using fire and candles to the modern era of electric lighting, the evolution of light sources has been remarkable. One significant component in the history and development of electric lighting is the bulb, which has seen numerous transformations over the years, leading to more efficient, durable, and environmentally friendly options. The Development of Bulbs The journey of the bulb from its inception to the present day is a story of innovation and technological advancement. The first incandescent bulbs, developed in the 19th century, used a carbon filament that glowed when an electric current was passed through it. Though these early bulbs were rudimentary and had a short lifespan, they marked the beginning of a new era in lighting.
