Lamp holders, also known as lamp adapters, are devices that are used to secure and provide electrical connection to a light bulb. They come in various shapes and sizes, depending on the type of light bulb and the fixture it is being used in. Some common types of lamp holders include:
Edison screw (E27 or E26)
Bayonet cap (B22 or B15)
Lamp holders serve as an interface between the light bulb and the wiring of the fixture, allowing for easy installation and replacement of light bulbs. Some lamp holders also come with additional features such as spring-loaded mechanisms, heat-resistant materials, and insulation to ensure safety and longevity.
It is important to choose the correct lamp holder for your light fixture, as using an incompatible holder can result in poor electrical contact, fire hazard, or other safety issues.
