Lamp chemistry includes all of the chemical parts and pieces that make up the internal fluorescent lamps on the market today. The lamps are often going to contain an acrylic shell, and they will have the chemicals housed inside the highest quality borosilicate glass. The internal coating on the tubes is going to be halophosphate. This is the most common type of tube on the market today, but it is not the only option.
The triphosphor bulbs are a different type of bulb, which came to use most prominently in the 1970s and beyond. Before this time, people thought that it was necessary to have all spectrums of light represented in order to show true color to the human eye. However, they discovered that the eye is not equally sensitive to all colors. This type of lighting then started to use just three bands – red, green, and blue. The first company to create these lamps was Westinghouse.
