Answer. Explanation: Main reason why electric bulb is filled with nitrogen or argon instead of air is that the bulb contains closed glass chamber with inactive (inert) gas called Argon. Glass chamber in bulb gets filled with the air with presence of oxygen causing filament to burn to react with oxygen.
Q. Why are LED bulbs preferred ordinary?
LEDs use much less energy than incandescent bulbs because diode light is much more efficient, power-wise, than filament light. LED bulbs use more than 75% less energy than incandescent lighting. Another advantage of LEDs is the “hassle factor.” LEDs last a lot longer than a regular bulb.

Q. Which property of Argon is used in light bulbs?
Did you know that incandescent light bulbs are filled with inert gases like argon? The heat from the tungsten filament generates light and the argon helps prevent the filament from decaying. Simply having air in the bulb would not work as the filament would react with the oxygen in the air and burn out the tungsten.
Q. Why noble gases are used in electric bulbs?
Because the noble gases have a complete outer shell of eight electrons (except for helium, which has just two), they are very resistant to forming bonds. In these lamps, a high voltage electrical discharge is passed through a tube of low-pressure neon gas.
Q. Which gas is used in CFL?
Features of Compact Fluorescent Lamp (CFL) It contains a low-pressure mix of argon gas, mercury vapour, and liquid mercury, and is coated on the inside with three different phosphorous substances.
Q. Which metal is used in Tubelight?
This lamp consists of a glass tube filled with an inert gas (usually argon) at low pressure. On each side of the tube you will find a tungsten electrode. The ballast regulates AC power to the electrodes. Older lamps used a starter to get the lamp going.
Q. Is LED light bad for the eyes?
The “blue light” in LED lighting can damage the eye’s retina and disturb natural sleep rhythms, France’s government-run health watchdog said this week. LED uses only a fifth of the electricity needed for an incandescent bulb of comparable brightness. …
Q. What does a red light on a house mean?
Traditionally, it means a whore house/prostitution. Some people do it because they think they are supporting firefighters, just as green bulbs became symbolic of support for the military a few years ago. The latest rumor is that anti-gun liberals are shining the red light to oppose guns.
