What is an E12 Socket?


In the world of lighting fixtures, there are various types of sockets that play a crucial role in determining the compatibility and functionality of light bulbs. One such socket is the E12 socket, which is widely used in many residential and commercial lighting applications. In this article, we will delve into the specifics of what an E12 socket is, its features, and its common uses.


What is an E12 Socket?


The term "E12" refers to the base or socket type used in a light fixture. It is also known as a candelabra base due to its resemblance to the candleholders found in chandeliers. The "E" stands for Edison, paying homage to Thomas Edison, the inventor of the modern electric light bulb. The number "12" denotes the approximate diameter (in millimeters) of the screw base.


Features and Specifications


The E12 socket is characterized by its small, screw-in base with a diameter of approximately 12mm. It typically consists of a threaded metal collar and contacts that securely hold the light bulb in place. Due to its compact size, this socket is commonly found in smaller lamps, chandeliers, pendant lights, and decorative fixtures.


Uses and Applications


E12 sockets are primarily used for incandescent and halogen bulbs, but they can also accommodate some LED and compact fluorescent (CFL) bulbs. These sockets are commonly found in decorative and accent lighting fixtures, specifically those designed to emit softer, ambient lighting. Chandeliers and candelabras are often equipped with E12 sockets, providing an elegant and traditional aesthetic.


Advantages of E12 Sockets


1. Versatility: E12 sockets are compatible with a wide range of lighting technologies, making them versatile for various applications.

2. Style: The small size of the E12 socket allows for intricate and decorative designs, making it ideal for visually pleasing fixtures.

3. Dimming Capability: Unlike some other socket types, E12 sockets often offer dimming capabilities, providing users with control over the lighting intensity.



The E12 socket, also known as the candelabra base, is a widely used socket in lighting fixtures that require smaller bulbs. Its compact size, versatility, and compatibility make it a popular choice for residential and commercial applications. Whether you're looking to illuminate a chandelier or enhance the ambiance of a room with decorative lighting, the E12 socket provides an excellent solution for your lighting needs.
