The fluorescent light technology has been available for more than 150 years already. The development is due to the work of many intelligent scientists and inventors and if you want to know specifics of the history, then read this article.
The 19th Century
The earliest fluorescent lights were first invented in 1856 by Heinrich Geissler. He had found that gas-filled tubes were able to produce some luminance when they’re stimulated by electricity. It’s amusing to know that he had not intended to discover this. Nevertheless, his inventions became an important part to the future development of fluorescent technology. As the end of the 19th century drew close, many scientists experimented with Geissler’s findings and adapted them to their own work. One of these was the late great Thomas Edison and he expanded upon Geissler’s work (and other scientists) and created the first long-lasting light bulb that we know today.
Beginning of the 20th Century
The first fluorescent light was successfully made in 1901 by Peter Cooper Hewitt. He created a bulb that contained a tube on the inside that was filled with mercury and the low pressure mercury was then excited by electricity, resulting in UV light. This invention never made waves due to the strange light produced by this bulb. However, in 1926 the technology was improved upon by Edmund Germer who managed to stabilize the bulb and make the emitted light look more attractive. Success came fast after these changes.
The Mid 20th Century
As World War II was approaching, General Electric, or GE, purchased the patent for fluorescent light from Germer. This was the beginning of worldwide promotions for this new type of light bulb and it was even showcased at the World’s Fair in New York during the year 1939. Only during the war did energy efficiency become a priority and as a result incandescent lighting was being replaced with fluorescent lighting which was more energy efficient. The use of this bulb in businesses caused the demand for fluorescent bulbs to increase dramatically.
Last-quarter 20th Century
As the final world war halted and the world moved on into the 50s and the 60s, the fluorescent light bulb became a common lighting system that was used mainly by various organizations and businesses. They became a very attractive alternative to the more prominent incandescent light bulbs during those years. However, most homeowners didn’t really catch on to this technology due to the fact that fluorescent lights didn’t fit most residential light fixtures. When the 70s arrived, GE started coming up with ways to break through to the residential mainstream. Hired by GE, Ed Hammer developed the first CFL (Compact Fluorescent Lamp), thus allowing the company to cross the commercial barrier.
In the Near Future
With the gradual rise of the Green Movement (which started in the mid 90s), fluorescent lighting has become a powerful option for many people who want to contribute to energy efficiency, and ultimately, environmental stability. With the more recent Green Economy proposal, spearheaded by US President Barack Obama, energy efficiency will certainly be at the top of the list of priorities and fluorescent technology will be among them.
