In 1879, Thomas Edison filed for a patent for the first commercially successful incandescent light bulb. This was not, as many believe, the first time someone had created artificial light.
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.
That purpose turned out to be lighting for photographic studios and industrial use. George Westinghouse and Peter Cooper Hewitt formed the Westinghouse-controlled Cooper Hewitt Electric Company to produce the first commercial Mercury lamps. Marty Goodman in his History of Electric Lighting states, "In 1901, a now-forgotten inventor named Peter Cooper Hewitt invented an arc lamp that used mercury vapor. e14 led candle light bulb.
The vapor was enclosed in a glass bulb. This was the first enclosed arc-type lamp using metal vapor. In 1934, a high-pressure variant of this was developed [by Edmund Germer], which could handle a lot more power in a smaller space...The low-pressure mercury arc lamp of Peter Cooper Hewitt is the very direct parent of today's modern fluorescent lights.
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.
