Tungsten lamps use a filament made of tungsten, while carbon lamps use a filament made of carbon. Tungsten lamps have a longer lifespan and higher efficiency compared to carbon lamps. Additionally, tungsten lamps produce a whiter and brighter light compared to the yellowish light produced by carbon lamps.

Why are V-i characterstics different for tungsten and carbon lamp?
The V-I characteristics are different for tungsten and carbon lamps because of their different electrical resistances and thermal properties. Tungsten lamps have a higher resistance and operate at higher temperatures, resulting in a steeper voltage-current relationship. Carbon lamps have lower resistance and operate at lower temperatures, leading to a shallower V-I curve.
What elements are used in light bulbs?
Light bulbs typically contain a filament (often made of tungsten), a glass enclosure, and an inert gas like argon or nitrogen to prevent the filament from burning out too quickly. They also have a base to connect to the electrical circuit.
What element was used in incandescent lamps?
Incandescent light bulbs use a tungsten filament as the element that emits light when heated by an electric current.
What is the difference between a metal halide lamp and a halogen lamp?
Metal halide lamps produce light by discharging an arc through a mixture of gases and metal halides, resulting in a brighter and more efficient light output compared to halogen lamps. Halogen lamps use a tungsten filament surrounded by halogen gas to produce light, giving off a warmer color temperature and often used in applications where color rendition is important.
What is the difference between hydrogen and deuterium lamp for UV?
Deuterium lamps produce UV light using deuterium gas, whereas hydrogen lamps use hydrogen gas. Deuterium lamps provide a higher intensity of light in the UV range compared to hydrogen lamps, making them more suitable for applications requiring high UV output. Deuterium lamps also have a longer lifetime and are more stable in their output over time compared to hydrogen lamps.

What is lamp types?
There are two types of lamps the tungsten halogen lamps and incandescent lamps. Tungsten Halogen Lamps are similar to incandescent lamps and produce light in the same manner from a tungsten filament; however the bulb contains a halogen gas (bromine or iodine) which is active in controlling tungsten evaporation, whereas the incandescent lamp suppresses tungsten evaporation.
Which is a filling gas that's used in tungsten-halogen lamps?
That'd be Halogen.

Incandescent light bulbs use a tungsten filament as the element that emits light when heated by an electric current.
Is zircon used in incandescent lamps?
No, zircon is not used in incandescent lamps. Tungsten is the primary material used for the filament in incandescent lamps due to its high melting point and ability to produce light when heated.
What is the difference between a UV light bulb and a black light?
A black light is a UV emitting bulb. There are other types of UV bulbs, but most have very specific uses, such as: bug lights, tanning bed lamps, drying lamps for lithographic applications and printing, and medical diagnosis. All lamps--incandescent, fluorescent, mercury vapor, tungsten, etc.-- emit some range of UV light, so could be considered UV lamps, but that is not their specific purpose, and the amounts or levels vary widely.
How many types of lamps are there?
There are many different types of desk lamp, ranging from lamps using traditional tungsten (or enerygy saving bulbs) to lamps using the more powerful halogen lamp. These are usually used where brighter light is required.
What element is used in carbonarc lamps?
Carbonarc lamps use carbon rods as electrodes, which produce an electric arc that generates light.
What is the difference between daylight fluorescent and cool white fluorescent?
Daylight Fluorescent lamps have bluish-white illuminance, whereas coolwhite fluorescent lamps have yellowish-white illuminance.
How many types of desk lamps are there?

Which element is used in the filaments in incandescent lamps?
Tungsten is commonly used in the filaments of incandescent lamps because it has a high melting point and does not easily evaporate at high temperatures, making it suitable for prolonged use as a source of light.
