    Lamps turn electrical energy into light. There are many different types and styles of lamps. Some are used in small applications, while others are used in residential or industrial sites. Light symbols vary with application and manufacturer. Typical residential incandescent and fluorescent lights are shown in Figure \(\PageIndex{1}\). The incandescent lamp is available in different watt ratings. The fluorescent lamp is available in different lengths, wattages, and types of illumination. It is easily recognizable by its long tube shape.

    Light-duty incandescent lamps

    Light-duty incandescent lamps most commonly have bases that are either the screw-type or the bayonet type Figure \(\PageIndex{2}\).

    The amount of illumination from the neon lamp (Figure \(\PageIndex{3}\)) is small. The neon lamp uses minimal current but needs higher voltage.

    Lamp holders

    Lamp holders (Figure \(\PageIndex{4}\)) are used to hold lamps and provide a means of connecting the lamp to the electrical circuit. Incandescent lamps use a screw-type attachment. This may be housed in a plastic or porcelain body. Some lamp holders have built-in switches. Fluorescent lamp holders are available in different styles and sizes.
