This is different depending on the type of bulb. Most bulbs copper or kovar (or other alloy with thermal expansion rate matching that of glass) wires are used for connections.
- tungsten wire is used in incandescent bulbs for the filament
- Mercury liquid (which evaporates to form mercury vapor) is used in fluorescent bulbs and tubes as well as mercury vapor streetlight bulbs
- sodium vapor is used in both high pressure sodium and low pressure sodium streetlight bulbs
- tungsten studs are used as discharge electrodes in HID car headlight bulbs
- etc.

Do uranium use in light bulb?
Uranium is not commonly used in light bulbs. Light bulbs typically use tungsten filaments to produce light when an electric current passes through them. Uranium is more commonly used in nuclear reactors to generate electricity.
What Element that was originally called wolfram?
It is Tungsten metal which has highest Melting point among metals and therefore used in electric bulbs.
Can CFL light bulbs be used in recessed lighting?
Yes, CFL light bulbs can be used in recessed lighting.
Are light bulbs inorganic or organic?
Light bulbs are primarily made of inorganic materials. The glass casing is composed of silica (sand), while the metal components, such as the base and filament (in incandescent bulbs), are typically made from metals like tungsten or aluminum. Some light bulbs, like compact fluorescents and LEDs, also contain inorganic phosphors and semiconductors. Overall, the materials used in light bulbs are largely inorganic in nature.
Is used light bulbs organic or inorganic?
Used light bulbs are considered inorganic waste. They typically contain materials like glass, metal, and sometimes hazardous substances such as mercury, depending on the type of bulb. While some components can be recycled, the overall composition does not classify them as organic materials. Proper disposal and recycling are important to handle the potential environmental risks associated with used light bulbs.
Which transition metal is used in light bulbs as a filament?
Tungsten is the transition metal commonly used in light bulbs as a filament. It has a high melting point and is able to withstand the high temperatures generated by the electric current passing through it, making it ideal for producing light.
What metal is used in domestic lightbulbs?
The type of metal that is used in domestic light bulbs is known as tungsten. This is the metal that is usually found in incandescent light bulbs.
What metal use the filaments in light bulbs?
Tungsten is used in filaments of light bulbs.
What metal would not melt on mercury?
There are several such as Tungsten a metal used in electric bulbs.
What is a filament that glows white hot in electric light bulbs?
Tungsten is the filament used in electric light bulbs that glows white hot when subjected to an electric current.
Where are electric bulbs usually used?
Where natural light is insufficient.
What is the metal in domestic light bulbs?
The metal used in domestic light bulbs is typically tungsten. Tungsten has a high melting point and is able to withstand the high temperatures generated by the electric current passing through it, making it ideal for use in light bulb filaments.
Transition metal used in incandescent light bulbs?
tungsten
What element is a silvery white metal used in flare fireworks and photographic light bulbs?
Magnesium is a silvery white metal used in flares fireworks and photographic light bulbs
What metal is commonly used in flash bulbs for producing light?
Magnesium is commonly used in flash bulbs because it produces a bright white light when ignited.
Do uranium use in light bulb?
Uranium is not commonly used in light bulbs. Light bulbs typically use tungsten filaments to produce light when an electric current passes through them. Uranium is more commonly used in nuclear reactors to generate electricity.
What element is used for a filament for light bulbs?
Tungsten is typically used as the filament in incandescent light bulbs because of its high melting point and ability to emit light efficiently when heated by an electric current.
