American, Peter Cooper Hewitt patented the first mercury vapor lamp in 1901. The low-pressure mercury arc lamp of Peter Cooper Hewitt is the very first prototype of today's modern fluorescent lights. 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.
But within the lifetimes of many of us, it was not always so. Our acquaintance with fluorescence was then limited to high-school science classes. There, our teacher would draw the shades to darken the room, turn on an incandescent or small mercury-vapor lamp with a purple glass filter, and shine it on selected mineral specimens. Then, to our dark-adapted eyes, we would see them glow in a variety of colors. It didn't seem possible that this darkroom phenomenon could ever be the basis for a practical light source.
Since that time, great improvements and scientific breakthroughs have continued to shape the way we illuminate our world. The next big leap in the evolution of lighting was the introduction of the fluorescent light bulb. Riding in on the coattails of the mercury vacuum pump invented by a German glassblower named Heinrich Geissler. Mr. Geissler's pump allowed him to evacuate the air from a glass tube which created a greater vacuum than had been previously possible. When electricity was run through the "Geissler tube" it began to emit a strong, green, fluorescent, glow.
Rocks and other types of mineral material had been observed to "fluoresce" for hundreds of years, but it was now possible to capture and control that energy. Primarily viewed as a source of amusement Geissler's discoveries helped to pave the way for future developments of the fluorescent light bulb.
George Inman and Richard Thayer - The First Commercial Fluorescent Lamp George Inman lead a group of General Electric scientists researching an improved and practical fluorescent lamp. Under pressure from many competing companies the team designed the first practical and viable fluorescent lamp that was first sold in 1938. It should be noted that General Electric bought the patent rights to Edmund Germer's earlier patent.
However, there is a barrage of cheap lightings being imported and sold, that do not comply with the flag statute. This is bad for a number of reasons. Imported stuff is cheaply made and more importantly, the designs, materials, colors, and methods do not compare well with the better quality, longer-lasting, and correctly designed lightings made by American manufacturers. The Flag Company Inc specialized in flags and lightings offered a special edition of fluorescent lightings to provide innovative solutions for individual projects.
