The Flag Company Inc And History Of Fluorescent Lightings

By Antony Pharel


In our everyday life, fluorescence plays a prominent part, - on our TV screens and in our lighting. The familiar incandescent lamp invented by Edison still predominates in our homes, but elsewhere, - in all commercial and industrial lighting uses, - fluorescent lamps have become the principal artificial light source.

As early as 1800, Italian inventor Alessandro Volta, while working on his idea for an electric battery, conducted electricity through a copper wire which heated up to a white hot glow. Technically, this is considered one of the first examples of incandescent light.

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.

Later improvements included using mercury vapor, carbon dioxide, and nitrogen as mediums that filled the bulb in an attempt to discover the right combination of materials for a commercially viable gas-based light bulb. These days small amounts of mercury vapor are combined with xenon, neon, and krypton gasses, which are all pumped into an elongated glass tube. Electricity then passes through a ballast and is introduced to the gasses, which ignites a tungsten filament. Voila! Fluorescent light!

However, there is a barrage of cheap fluorescent 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.
