NEON
Argon gas is commonly used in fluorescent tube lights as a filler gas, while mercuric oxide is not typically used in tube lights. Instead, mercury vapor is used in conjunction with argon gas to produce ultraviolet light that activates the phosphor coating inside the tube to produce visible light.
A tube bulb works by passing an electric current through a gas or vapor inside the tube, which causes the gas particles to become excited and emit light. The tube is coated with a phosphor material that absorbs this light and re-emits it as visible light. The specific type of gas, voltage, and phosphor coating determine the color and intensity of the light produced.
The gas typically found in light bulbs is argon.
A discharge tube is a type of gas-filled tube that emits light when an electric current passes through it, commonly used in neon signs or plasma displays. On the other hand, a tube light is a type of fluorescent lamp that uses a phosphor coating inside a glass tube to produce light. While both types of tubes rely on gas and electric current to produce light, they differ in their construction and application.
The gas typically found in incandescent light bulbs is argon.

Mixture of argon gas and Mercury gas.
In a tube light, the gas inside the tube is typically a mixture of argon and mercury vapor. When electricity is applied to the tube, it ionizes the gas, creating a plasma by stripping electrons from the gas molecules. This ionization process allows for the generation of ultraviolet light, which then excites the phosphor coating on the inside of the tube, producing visible light.

A starter initially provides a path to complete the circuit. The tube light starts when the current flows through the ionized gas in the main tube. woodenboatusa.com
When viewing a discharge tube of gas through a hand-held spectroscope, bright lines appear because the gas inside the tube emits specific wavelengths of light when energized. The spectroscope separates the light into its component colors or wavelengths, allowing you to see the discrete emission lines characteristic of the gas present in the tube.
They are filled with a gas that is ignited, then glows.
If it's a *Crookes* tube you're asking about, it's a discharge tube because the applied electrical field causes ionization and a resulting discharge of energy in the form (mostly) of light, depending on the gas or gases in the tube.
