Incandescent lamps or general service lamps are thermal radiators. Light is produced as a result of the high temperature of the filament when a current is passed through it. Although incandescent lamps have a low luminous output and short service life, they are commonly used because of the pleasant color of the light and good color rendition characteristics and above all because of the low price. They are mainly employed in the home, restaurants and store windows.
