Question

What are the gasses found in a lightbulb?

Answer 1

neon

Answer 2

Ordinary light bulbs don't contain gases. Halogen, neon, sulphur are some of the many gases use in industrial/special propose bulbs. Like halogen spotlights, neon signages & street lightings. These gases generate a brighter light than the normal incandescent light bulb.

Answer 3

General service incandescent light bulbs over 25 watts in rating are now filled with a mixture of mostly argon and some nitrogen, or krypton. More nitrogen is used in higher-voltage lamps to reduce the possibility of arcing.

Flourescent light bulbs are filled with mercury vapor and argon, xenon, neon, or krypton.

Answer 4

In your average 60W bulb, you've got a tungsten coil that is placed in a bulb containing Argon gas.

If you're thinking Vegas lighting, Neon is probably the best bet on what they're using.

For flood lamps (Halogen lights) and the like, they use gasses from the halogen group contained within a quartz casing with a tungsten filament.  The halogen gasses 'recycle' the tungsten as it evaporates.

Other gases used are Xenon, Krypton, Mercury, Nitrogen.  Most inert gases can be used in lightbulbs.

Answer 5

Typically Argon is used in incandescent light bulbs.  This gas is used to prevent the tungsten vapors from depositing on the inner wall of the bulb, making it dimmer.

The pressure of the Ar is less than the outside air.
