Ceramic lamp socket is a type of electrical socket that uses a ceramic material as its insulating material. Ceramic is a highly durable and heat-resistant material, making it ideal for use in high-temperature applications and electrical components. Ceramic sockets are commonly used in electrical devices and equipment, such as lamps, appliances, and electronic devices, where they provide a secure and stable connection for electrical plugs. They are also often used in high-power applications where heat dissipation is a concern. The use of ceramic as the insulating material helps to ensure the safety of the electrical connection and the longevity of the socket.

E27 Porcelain lamp holders

E27 is a common designation for a type of screw-base electrical socket commonly used for light bulbs. The "E" stands for Edison, the inventor of the light bulb, and the "27" refers to the diameter of the socket base in millimeters. The term "porcelain lamp holder" is sometimes used to describe this type of socket because it is often made of porcelain, a type of ceramic material that is highly durable and heat-resistant. E27 porcelain lamp holders are commonly used in a variety of lighting applications, including residential, commercial, and industrial lighting. They are also commonly used in table lamps, floor lamps, and other types of light fixtures. The screw-base design of the E27 socket allows for easy installation and replacement of light bulbs, and its porcelain construction provides a stable and secure connection for the bulb.
