Well, it is certainly not a globe with just electrons glowing inside it!
The globe contains a very hot ionized gas, which is known as a plasma.
A plasma is defined as:
An electrically neutral, highly ionized gas composed of ions, electrons, and neutral particles. It is a phase of matter distinct from solids, liquids, and normal gases.
A special physical feature is exploited in halogen lamps: when small amounts of a halogen gas were added to the contents of the light bulb, these were found to help to return large quantities of evaporated tungsten atoms back to the filament.
This treatment results in a significantly longer lifetime of such lamps.
Additionally it has the benefit that halogen light bulbs can be operated at a higher temperature than can be used for ordinary light bulbs. This results in less heat production compared to light output and an overall much higher efficiency in the conversion of the energy input (electrical energy) to the energy output as light.
General note about how all incandescent filament light bulbs operate
An electrical current travelling through the filament of a light bulb makes it glow white-hot and generate both light and heat because of the electrical resistance of the filament.
The filament is normally mounted within a special mixture of noble and/or inert gases held inside the glass enclosure of the light bulb, held at a pressure which is close to a vacuum.
The special mixture of gases prevents the filament from oxidizing and burning away, which would happen extremely quickly if it glowed white-hot in normal air which contains oxygen.
A halogen lightbulb uses a material called tungsten. The tungsten is in a gas filled bulb, but the pressure is higher than a regular lightbub. The reason for this is that the halogen lightbulb has a much smaller area than the other type. The trouble with this is that they can get very hot, making them almost dangerous to touch while on.
Depends. Lamps can certainly be built to work on either AC, or DC, or both. But some lamps, particularly those with electronics in them, either a dimmable lamp, or a fluorescent lamp, may only work with one type of electricity.
he invented the steam locomotive and a safe work lamp that didn't explode for miners to use in 1815

For lighting, PL-C Lamp is the acronym for Philips Linear - Compact (PL-C) Flourescent Lamp.
The Davy lamp was used to tell the miners if they hit a spot of dangerous gas's flame would go out every time they hit a spot of dangerous gas and because of that little lamp allot of miners lives were saved.
Plasma globes or plasma lamps are filled with noble gases and a high voltage electrode. The most common gasses are neon, argon, xenon, and krypton.
The halogen bulb produces a plasma arc on the inside of its quartz filament. Plasma glows at thousands of degrees. That's why they are hot.
A plasma arc of argon gas and/or other ions, such as mercury vapour, depending on the gas mixture used in the lamp.
Glowing plasma is evident in the light from the aurora borealis and a fluorescent lamp. The aurora borealis is also known as the northern lights.
You might be thinking of a Plasma Lamp.
The oil will not work as plasma in the blood.
If the ballast on a fluorescent light blows the lamp will not work.
Plasma helps stop blood from flowing out of your body when you have a cut.
This is the first time someone mentions the plasma ball in the few years I been in wikianswers. I like this question because with the plasma ball we could see how Tesla conducted his experiments. Tesla invented the plasma lamp for his experiments with high frequency currents of electricity in a vacuum glass tube, scientifically called an "evacuated tube" The Plasma Ball or lamp was actually first named by Tesla as "an inert gas discharge tube" for a better description. He wanted better light bulbs and he created those as well.
Plasma cutters work by shooting a high-pressure gas through a hose and arcing electricity through the gas to create plasma. Basically, plasma cutters used high temperature gas and electricity to cut through metals.

Lamp, because you need electricity for the lamp to work
