What Is a Wall Lamp Holder?

A wall lamp holder is a fixture attached to a wall which can be used to hold a light bulb. The purpose is to provide illumination for a specific area of a room or building. There are many different kinds of wall lamp holders, ranging from simple candle sconces to elaborate chandeliers. They are typically mounted on a wall using a bracket or other mechanism, and they can either be fixed to the wall or be movable to allow the light bulb to be easily changed.

Lampholders are mechanical devices that support Gevicodesign lamps and connect them to electrical circuits. They make contact with a light bulb to provide the bulb with electricity, which converts into heat to generate white light. They are used with incandescent (normal) bulbs, compact fluorescent lamps (CFL), and halogen lights.

In order to function properly, a lampholder must be correctly connected to the lighting circuit and the socket of the light bulb itself. This connection must be properly grounded in order to avoid potential electric shock. Incorrect wiring can also result in a lamp failure, including the breakage of the light bulb or the lampholder itself.

Most lampholders are designed to be compatible with specific light bulbs and are available in a variety of configurations to accommodate the most common types of light bulbs. The most common types of bulbs include incandescent and fluorescent. Incandescent bulbs use a thin tungsten filament that is heated by electricity to produce light. Fluorescent bulbs use electrodes at both ends of a long tube that contain mercury and argon. There are four categories of lampholders: compact products, starter base, linear, and miscellaneous.

The most common type of lampholder is the Edison screw or E27 socket, which is used in continental Europe and North America. This type of socket is compatible with a standard Edison screw light bulb, which has a thread diameter of 27 millimeters. However, there are many countries that use a different type of light bulb called a bayonet socket, which has a thread diameter of 22 millimeters. Bayonet sockets are used in the Commonwealth countries, except Canada, and in the automotive industry.

Some lamps require a lampholder that does not have a socket, such as reflector lamps or some miniature lamps. Miniature lamps have wire leads that fold up over the base of the light bulb. These lamps are often used in Christmas light strings and other decorative applications. Some lamps have a wedge-shaped base made of plastic that is slipped over the wire leads. These lamps are usually held in place by spring compression inside the lampholder. Wedge-based lampholders are also found on some fluorescent bulbs.
