The E40 porcelain lamp holder is a type of lighting fixture, the sockets designed to hold and connect an E40 base light bulb to an electrical supply.

The E40 base is a large screw fitting commonly used in high wattage bulbs, such as metal halide or high-pressure sodium lamps, which are used for outdoor lighting, commercial lighting, and industrial lighting applications.

The porcelain material used in the holder is resistant to high temperatures, making it suitable for use with bulbs that generate a significant amount of heat.

The holder includes screw terminals for connecting the wires from the electrical supply, which are typically covered with a ceramic insulator for added safety.

E40 porcelain lamp holders are typically sold as a standalone component, allowing users to customize their lighting solutions by selecting the appropriate bulb and wiring.

They are available in a range of sizes and configurations to accommodate different bulb types and wattages.

When selecting an E40 porcelain lamp holder, it is important to ensure that the holder is rated for the wattage of the bulb being used to avoid overheating and potential fire hazards.
