Filament

Filament lighting is a type of incandescent lighting that uses an electric current to heat a thin wire filament until it starts to glow, emitting light. These bulbs are the most common form of light bulb found in households around the world. Filament lighting is generally considered inefficient due to its low luminous efficacy and short lifespan compared to other forms of lighting such as LEDs and CFLs. However, these lights still remain popular due to their affordability and warm tones, allowing them to be used in decorative applications such as chandeliers and lamps.
