Did you know that incandescent light bulbs are filled with inert gases
Why is argon used in making fluorescent tubes and bulbs?
Argon gas is used in fluorescent and incandescent light bulbs to stop the oxygen in the light bulbs from corroding the hot tungsten filament. The use of argon in light bulbs prevents the evaporation of the tungsten filaments , which results in increased light bulb life.
What gas is used in fluorescent light tubes?
A fluorescent lamp tube is filled with a gas containing low pressure mercury vapour and noble gases at a total pressure of about 0.3% of the atmospheric pressure.
Why is argon more suitable for light bulbs than oxygen?
Argon, rather than oxygen, is used in light bulbs, because it helps maintain the inert atmosphere needed for an igniting, illuminating tungsten filament to function safely . It also excludes oxygen, which would corrode the heated filament on contact.
What are 5 uses for argon?

- Other Common Uses of Argon Gas.
Is used in fluorescent tubes?
A fluorescent lamp consists of a glass tube filled with a mixture of argon and mercury vapour . Metal electrodes at each end are coated with an alkaline earth oxide that gives off electrons easily. When current flows through the gas between the electrodes, the gas is ionized and emits ultraviolet radiation.
Is LED better than fluorescent?
While fluorescent tubes are definitely more energy efficient than incandescent light bulbs and halogen lamps (which are just newer, brighter versions of incandescent bulbs) LEDs are even more energy efficient than fluorescents .
Why do fluorescent lamps work better now than they used to?
The phosphor fluoresces to produce light. A fluorescent bulb produces less heat , so it is much more efficient. A fluorescent bulb can produce between 50 and 100 lumens per watt. This makes fluorescent bulbs four to six times more efficient than incandescent bulbs.
Which gas is used in street light?
Sodium-vapour lamp, electric discharge lamp using ionized sodium, used for street lighting and other illumination. A low-pressure sodium-vapour (LPS) lamp contains an inner discharge tube made of borosilicate glass that is fitted with metal electrodes and filled with neon and argon gas and a little metallic sodium.
What Colour does argon glow?
Argon: produces a lavender light . Using phosphor-coated glass, argon creates several other colors. Xenon: produces a blue light. Radon: Because of its hazardous qualities, radon gas is not used in lighting.
Does argon gas glow when heated?
| Argon | Pronunciation /ˈɑːrɡɒn/ (AR-gon) | Appearance colorless gas exhibiting a lilac/violet glow when placed in an electric field | Standard atomic weight A r , std (Ar) [39.792, 39.963] conventional: 39.95 | Argon in the periodic table |

Does tungsten burn in oxygen?
Reaction of tungsten with air
At room temperature, tungsten does not react with air or oxygen, O 2 . At elevated temperatures (red heat), the trioxide tungsten(VI) oxide, WO 3 , is formd.
What happens if you inhale argon gas?
Inhalation: This gas is inert and is classified as a simple asphyxiant. Inhalation in excessive concentrations can result in dizziness, nausea, vomiting, loss of consciousness, and death . Death may result from errors in judgment, confusion, or loss of consciousness which prevent self-rescue.
What is argon most commonly used for?
Argon is often used when an inert atmosphere is needed . It is used in this way for the production of titanium and other reactive elements. It is also used by welders to protect the weld area and in incandescent light bulbs to stop oxygen from corroding the filament.
Is argon a dry gas?
Argon is the most common gas in the atmosphere besides Nitrogen and Oxygen. Argon is a noble gas (like helium) which means that it is completely inert . Argon will not readily react with any other substance. ... Since it is such a small percentage of the atmosphere Argon is many times more expensive than Nitrogen.
Why is my fluorescent light flickering?
If your fluorescent bulbs flicker, most likely the problem is with the bulb itself . If the bulb is very dark on either end, it may be defective and burned out. The best way to test the functionality of a bulb is to put it into a fixture you know works. ... Flickering fluorescent lights can also be a result of temperature.
