Tungsten is used as filament because of its high melting point and has high resistance which converts electricity into light energy easily.
The tungsten filament lamp temperature is about 2800–3300 K and consists of a linear double-ended quartz tube containing a tungsten filament, which is resistivity heated.
In candescent light bulbs have filaments which are made mainly from the element tungsten, the metal element used for the filaments in incandescent light bulbs.
The major disadvantage associated with filament bulbs is its cost. Though the initial costs are less, over the period, the current bills are going to be high since filament bulbs draw large units of power. This is because the filament bulbs spend nearly ninety percent of the power drawn in the form of heat.
Filament LED bulbs usually looks like a traditional glass light bulbs. The yellow strip that provides the light, was created to look like the filament of an incandescent light bulb, hence the term LED filament bulb.
A filament lamp is a common type of light bulb. It contains a thin coil of wire called the filament. This heats up when an electric current passes through it, and produces light as a result. The resistance of a lamp increases as the temperature of its filament increases.
