Florissant lights
A fluorescent lamp tube is filled with a gas containing low-pressure mercury vapor and argon, xenon, neon, or krypton. The pressure inside the lamp is around 0.3% of atmospheric pressure.

Neon and Argon Glow Lamps - How they work & History. The Neon lamp is a low pressure gas discharge lamp. It is a cold cathode fluorescent lamp (CCFL). The term "Neon Lamp" is used to describe a CCFL with a tube diameter less than 15 millimeters.

Why Argon is used in fluorescent Lights
It is a cold cathode fluorescent lamp (CCFL). Argon gas is used in other fluorescents as well because of a lower striking temperature. After the argon strikes an arc the neon gas is warmed and current is able to flow through the neon gas, ionizing more atoms as the current rises.
Neon Lights
Neon is a chemical element with symbol Ne and atomic number 10. It is a noble gas. Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air.
What are the Noble gases
Along the extreme right-hand column of the periodic table of elements is a group known as the noble gases: helium, neon, argon, krypton, xenon, and radon. Also known as the rare gases, they once were called inert gases, because scientists believed them incapable of reacting with other elements.
Is Argon dangerousAlthough argon is non-toxic, it is 38% denser than air and therefore considered a dangerousasphyxiant in closed areas. It is difficult to detect because it is colorless, odorless, and tasteless.
Why is argon a insert gas |
Argon is the third noble gas, in period 8, and it makes up about 1% of the Earth's atmosphere. Argon has approximately the same solubility as oxygen and it is 2.5 times as soluble in water as nitrogen . This chemically inert element is colorless and odorless in both its liquid and gaseousforms.
