A Short History of Compact
Fluorescent Lamps
In 1856 a man by the name of Heinrich Geissler created a bluish glow
from a gas sealed in a tube. This glow was obtained by exciting the gas
with an induction coil. Heinrich Geissler was educated as a glassblower
he is best remembered as a physicist.
In 1893 during the World’s Fair located at the World Columbian
Exposition in Chicago, Illinois, fluorescent lights were displayed by
Nikola Tesla.
The Moore lamp, a commercial gas discharge lamp was created in 1894 by
D. McFarlane Moore. Mr. Moore created this lamp in the hopes that it
would compete with the incandescent light bulb created by his former
boss Thomas Edison. Mr. Moore’s lamp was created using nitrogen and
carbon dioxide gases that emitted a pink and white light.
The Mercury-Vapor lamp which emitted a bluish green color light was
shown in 1901 by Peter Cooper Hewitt. Because of the light color that
was outputted by this lamp it was deemed unusable for most purposes.
This lamp did have some minor success in photography applications where
color was not yet an issue, due in great part to its high efficiency
output.
The man recognized today as the inventor of the fluorescent lamp was
Edmund Germer. In 1926 Mr. Germer and some of his coworkers were able to
increase the operating pressure with the fluorescent tube and also
proposed coating the inside of the tube with a fluorescent powder that
would convert ultraviolet light into a more normal and uniform white
colored light.
Around 1938 General Electric bought Mr. Germer’s patent and was able
under the direction of George Inman to bring the fluorescent lamp into
commercial applications.
