What You'll Learn
The first constant electric light was demonstrated in 1835
This breakthrough in 1835 served as a catalyst for further advancements in the field. Over the next four decades, scientists worldwide dedicated their efforts to refining the incandescent lamp. They experimented with different filament materials, such as platinum, carbon, and iridium wires, and explored the use of evacuated or semi-evacuated enclosures to prolong the filament's life and enhance the bulb's overall durability. These early attempts faced challenges due to the short lifespans of the bulbs, high production costs, and excessive energy consumption.
During this period of experimentation, British physicist and chemist Joseph Swan emerged as a notable figure. Beginning in 1850, Swan conducted experiments with carbonized paper filaments in an evacuated glass bulb. Despite achieving some success, he faced challenges due to the lack of an effective vacuum, resulting in a short bulb lifespan and inefficient lighting. Swan's perseverance led him to collaborate with Charles Stearn, an expert in vacuums, and by December 1878, he successfully demonstrated his lighting using a thin carbon rod. However, this early version still lacked commercial viability due to the need for large conductors.
Thomas Edison, a renowned inventor, also played a pivotal role in the evolution of electric lighting. In 1879, he conducted his first successful test of an electric light bulb, and by the end of that year, he held the first public demonstration of his new light in Menlo Park, New Jersey. Edison's work extended beyond improving the bulb itself; he developed a comprehensive system for distributing electricity and tracking its usage through the invention of the first electric meter.
The contributions of Lindsay, Swan, and Edison, along with many other inventors, laid the foundation for the widespread adoption of electric lighting. These pioneers tackled the challenges of creating durable filaments, improving vacuum technology, and enhancing the efficiency of the bulbs. Their collective efforts transformed the way we illuminate our streets, homes, and workplaces, ushering in a new era of lighting technology.

The incandescent lamp was developed in the 1920s
The incandescent lamp was not developed in the 1920s. In fact, the story of its development goes back much further, to the early 19th century.
The first constant electric light was demonstrated in 1835 by James Bowman Lindsay, who showed that he could "read a book at a distance of one and a half feet". Following this, scientists around the world spent the next 40 years working on the incandescent lamp, experimenting with the filament and the bulb's atmosphere. These early bulbs had very short lifespans, were too expensive to produce, and used too much energy.
In the 1870s, Joseph Swan and Thomas Edison famously produced commercially viable lamp bulbs. Edison's team produced a light bulb with a carbonized filament of uncoated cotton thread that could last for 14.5 hours. They continued to experiment until they settled on a bamboo filament, which gave Edison's lamps a lifetime of up to 1,200 hours. Edison also made other improvements to the lighting system, such as developing the first electric meter and the first commercial power utility.
Other inventors, such as William Sawyer, Albon Man, and Alessandro Cruto, also made significant contributions to the development of the incandescent lamp. Despite this long history of development, it is Edison's name that is most associated with the light bulb today. This is because his version was the first practical implementation, outstripping others due to a combination of factors, including an effective incandescent material and a high vacuum.

Thomas Edison's commercially viable light bulb in 1879
Thomas Alva Edison is often credited with inventing the first electric light bulb in 1879. However, he was not the first person to create an electric light. By the time Edison entered the lighting scene, electric arc streetlamps had been illuminating streets since the 1870s. These streetlamps produced light by arcing an electric current between two carbon rods.
Edison's incandescent light bulb differed from these earlier electric lights in that it was the first to be practical and affordable for home illumination. Edison and his team at his ""invention factory"" in Menlo Park, New Jersey, tested thousands of potential filament materials before settling on carbonized bamboo. This filament was durable and inexpensive, and it could be housed in a glass vacuum bulb. Edison's lamp only burned for a few short hours when he first tested it in January 1879, but by October of the same year, he had produced a light bulb that could last for 14.5 hours. On October 21, 1879, Edison made his incandescent light bulb publicly available for the first time.
Edison's work on the incandescent light bulb was part of a decades-long effort to develop a viable electric domestic lighting solution. The main challenges facing early experimenters were creating a durable filament that produced a bright and steady light and crafting the best possible vacuum inside the bulb to prolong the filament's life. Edison's eventual success in overcoming these challenges was due to his persistence in testing new materials and his focus on improving the filament.
Edison's contributions to electric lighting extended beyond the light bulb itself. He developed a suite of inventions that made the use of light bulbs practical, including a system for distributing electricity from a centrally located generator and the first electric meter. Edison also founded the Edison Illuminating Company in 1880 and established the first investor-owned electric utility. His work on the lighting system and his improvements to the generation of electricity helped make his incandescent light bulb a commercial success.

Humphry Davy's first practical electric light in the early 19th century
Humphry Davy, a British chemist and inventor, is credited with creating the first constant electric light in 1802. He had the most powerful electrical battery in the world at the time, housed at the Royal Institution. Davy created the first incandescent light by passing an electric current through a thin strip of platinum, chosen for its extremely high melting point. However, this early experiment was neither sufficiently bright nor long-lasting enough to be practical.
By 1806, Davy had developed a much more powerful form of electric lighting, which he demonstrated to the Royal Society in London. This was an early form of arc light that produced illumination from an electric arc created between two charcoal rods. This was the first practical electric light, and it would go on to illuminate town squares, hotel lobbies, and shop windows in the 1870s.
While Davy's arc lamp was a significant advancement, it had its drawbacks. In homes, the overwhelming brightness and flickering made it less than ideal. As a result, other inventors focused their efforts on improving the incandescent light bulb, which was lit by an electrified glowing filament. This presented a new set of challenges, as the right filament material had to be found to ensure sufficient brightness and longevity.
Scientists like Joseph Swan began experimenting with different filament materials as early as the 1840s. However, it wasn't until the 1870s that he and Thomas Edison produced commercially viable lamp bulbs. Edison and his team at Menlo Park tested various materials, returning to a carbon filament that could last for 14.5 hours. They continued to refine the filament, eventually settling on bamboo, which gave their lamps a lifetime of up to 1,200 hours.

The first neon light was introduced by Georges Claude in 1910
The story of lighting our homes and streets has evolved from oil lamps to gas lighting and, eventually, electric lighting. The first constant electric light was demonstrated in 1835, and scientists worked on improving the incandescent lamp bulb over the next several decades.
In 1879, Thomas Edison and his team produced a light bulb with a carbonized filament of uncoated cotton thread, which had a lifespan of 14.5 hours. Edison also developed the first commercial power utility, demonstrating that electricity could be distributed from a centrally located generator.
However, the first neon light, which used electricity in a different way, was introduced by Georges Claude in 1910. Claude was a French engineer, chemist, and inventor, born in Paris, France, in 1870. He founded the company Claude Neon Lights and is known for his work on the industrial liquefaction of air and the invention and commercialization of neon lighting.
Inspired by Geissler tubes and Daniel McFarlan Moore's invention of the "Moore tube," Claude developed neon tube lighting. These were glow discharge tubes that generated light when an electric current was passed through the rarefied gas within the tube. In 1910, Claude displayed his neon lamps to the public at the Paris Expo and Motor Show, marking the introduction of neon lighting.
Claude's associate, Jacques Fonseque, sold the first neon advertising sign to a Paris barber in 1912. By 1913, Claude wrote about his methods for purifying neon and other inert gases within a completely sealed glass tube, distinguishing his neon tube lighting from Moore tubes. In 1915, a U.S. patent was issued to Claude for the design of the electrodes for neon lights, strengthening his company's monopoly in the U.S. market.
