Thomas Edison briefly pursued fluorescent lighting for its commercial potential. He invented a fluorescent lamp in 1896 that used a coating of calcium tungstate as the fluorescing substance, excited by X-rays. Although it received a patent in 1907, [6] it was not put into production. As with a few other attempts to use Geissler tubes for ...
Jan 29, 2019 · How were fluorescent lights and lamps developed? When most people think of lighting and lamps, they think of the incandescent light bulb developed by Thomas Edison and other inventors. Incandescent light bulbs work by using electricity and a filament.

Fluorescent lighting, a staple in both residential and commercial spaces, has a rich history marked by innovation and technological advancements. This journey from its early experimental phases to becoming a widely sold lighting option reflects how advancements in one area can inspire progress across the entire lighting industry.
The concept of fluorescent lighting dates back to the 1890s when Thomas Edison experimented with a prototype that, despite its initial success, was impractical for prolonged use. The true foundation for fluorescent lighting was laid by Peter Cooper Hewitt, who introduced the mercury vapor lamp in the same era. His design featured glass tubes, which...
It was not until 1926 that fluorescent lighting began to take a more defined shape, thanks to Jacques Risler's innovation of adding a fluorescent coating inside the glass tubing of mercury lamps. However, the real breakthrough came in 1934 when General Electric launched the first commercially viable fluorescent lamps. These lamps quickly became pop...
In 1938, General Electric introduced the T12 and T8 models, enhancing the fluorescent lamp's design and utility. These models provided varying wattages—15 watts for the T12 and 30 watts for the T8—offering high performance for different applications. The evolution continued with significant contributions from Philips in 1980, who developed the firs...
The introduction of the T5 lamp in the 1990s marked another step forward, providing an even more efficient lighting solution. Despite the rise of LED technology, fluorescent lighting remained a prevalent choice due to its affordability and effective illumination for a long time. As of 2024, the popularity of fluorescent lighting has somewhat dimini...
Oct 1, 2024 · fluorescent lamp, electric discharge lamp, cooler and more efficient than incandescent lamps, that produces light by the fluorescence of a phosphor coating. A fluorescent lamp consists of a glass tube filled with a mixture of argon and mercury vapour.

A fluorescent light is a type of electric lamp that excites mercury vapor to create luminescence. The Smithsonian Institute states that, "Electrical inventor, Peter Cooper Hewitt built on the mid-19th century work of German physicist Julius Plucker and glassblower Heinrich Geissler.
The development of practical fluorescent lamps took decades, and many researchers contributed. Julius Plucker and Heinrich Geissler made glowing glass tubes in the 1850s, about the time George Stokes discovered that invisible ultraviolet light made some materials glow or "fluoresce."
Dec 2, 2020 · The use of fluorescent light began to emerge as soon as people started to understand the advantages and the fact that it was an upgraded version of the traditional bulb. Fluorescent Lighting is a continuous work in progress from the 1890s to date.
