A bulb using resistance to produce light when an electrical current passes through it. The conductor is usually a wire or filament.
A bulb that contains a conductive wire filament through which current flows. This is the most common type of light source.
is a type of artificial light source invented by Thomas Eddison in 1862. It has a good spectral response but low life and efficiency.
Light emitted from a burning filament in a glass bulb.
Passing electric current through a thin wire filament, usually a tungsten, produces light.
Light produced from man made sources such as florescent, or filament based lights. They emit cooler color temperatures than natural light (outdoor light). The lower color temperature causes a greater amounts of red to be present in incandescent light.
Bulb containing a conductive filament with current flowing through and an inert gas, which react together to create an intense heat, making the filament glow.
