The gas in a fluorescent light bulb tube is composed of Mercury, along with argon, xenon, krypton or neon. It is important to dispose of the tubes properly after they are used, since mercury can be toxic to people and animals if it is released into the environment.

What gas is in the fluorescent tube?
Usually it's mercury vapor.
What is the function of choke in tube lights?

Fluorescent lamp low pressure mercury vapour?
A fluorescent lamp refers to a low pressure mercury-vapor gas-discharge lamp that uses fluorescence in order to produce visible light. It is also called a fluorescent tube.
Is fluorescent light produced by heat?
Not in the way that an incandescent bulb does. A fluorescent lamp uses electricity to excite the particles of mercury vapor in the tube. This excited gas causes a phosphor to glow.

Exactly how well do LED lightbulbs work?
They are made with fluorescent tubes, bent and compacted to the size of a regular lightbulb. The inside of the tubes is filled with fluorescent gas and phosphor. Electricity passes into the tube and interacts with the gas to make ultraviolet rays and theseinteract with the phosphor and cause it to glow.
What are the positive points of ulteraviolet rays?
Ultraviolet rays can be used as for fluorescent lamps as certain chemicals glow when they absorb ultraviolet. In fluorescent lamps, the sindide of the tube is coated with a white powder that gives off light when it absorbs ultraviolet. The ultraviolet is produced by passing a current through a gas in the tube.
What is the difference between the normal light globe and a fluorescent tube?
"Normal" light globes use a glowing filament, heated by the current. Flourescent tubes ignite a gas within a tube, using an arc.
