argon gas preserve the filament from oxidation from high temperature
By replacing oxygen in the bulbs, argon can prevent the corrosion by oxidation of the filament.
The gas typically found in incandescent light bulbs is argon.
Argon
Argon(or nitrogen) and tungsten are used in incandescent light bulbs.
used as filling for fluorescent lamps, electric light bulbs, incandescent lamps and for vacuum tube.
Argon is commonly found in gas discharge tubes, incandescent light bulbs, and welding shielding gas.
Argon. As an inert gas, it makes the filament last longer. Some light bulbs also use Krypton.
Incandescent light bulbs use a combination of gases: argon and nitrogen. These gases help prevent the filament inside the bulb from evaporating too quickly, increasing the bulb's lifespan. LED bulbs do not use gas but instead rely on semiconductor technology to produce light.
Ordinary incandescent light bulbs are filled with an inert (electrically non-conducting) gas such as Nitrogen.Other types are filled with a gas containing low pressure mercury vapor and argon, xenon, neon or krypton.See the Related links for more information.
Incandescent bulbs use 75-100 watts. Fluorescent bulbs use around 10 watts. LED bulbs usually use 1 watt.
I am replacing all of my incandescent light bulbs today.
Argon and nitrogen are the two main gases used in bulbs today.See related links below
