What is G4 Socket?


When it comes to lighting solutions, there are various factors to consider, including the type of bulbs and sockets used. One such socket often utilized in modern lighting fixtures is the G4 socket. In this article, we will explore what a G4 socket is and how it enhances lighting solutions.


Understanding the G4 Socket


4 – 4 mm (0.15748 in) pin spacing.

The G4 socket is a type of bi-pin socket that is commonly utilized in low voltage lighting fixtures. The "G" in G4 refers to the "glass" that surrounds the bulb, emphasizing its use in halogen lamps. The "4" denotes the four-millimeter(0.15748 in) pin spacing between the two pins of the socket.


Advantages of G4 Sockets


1. Compact Size: G4 sockets are considerably smaller compared to other socket types, making them ideal for compact lighting fixtures. Their small size ensures that the entire light fixture remains sleek and unobtrusive, making them suitable for various applications, including display cabinets, recessed lighting, and under-cabinet lighting.


2. Versatility: G4 sockets are compatible with a range of light bulbs, including halogen, LED, and xenon bulbs. This versatility allows users to select the type of bulb that best suits their requirements, whether they prioritize energy efficiency, color temperature, or longevity.


3. Easy Installation: G4 sockets feature a simple design that allows for easy installation and replacement of bulbs. With just a simple pinching motion, the bulb can be easily inserted or removed from the socket. This ease of installation makes it hassle-free for users to maintain and replace bulbs when needed.


4. Accurate Lighting: G4 sockets ensure precise positioning and secure connection between the bulb and the fixture. This ensures consistent and accurate lighting, minimizing any flickering or loose connections. It provides stable illumination, making G4 sockets an excellent choice for lighting solutions where accurate light output is essential.


5. Energy Efficiency: G4 sockets are often used in conjunction with energy-efficient LED bulbs, which consume significantly less power compared to traditional halogen bulbs. This combination of a G4 socket with an LED bulb helps reduce energy consumption, leading to energy cost savings in the long run.



The G4 socket is a versatile and compact lighting socket that offers various advantages for lighting solutions. Its small size, easy installation, compatibility with different bulb types, and stable connections make it an excellent choice for both residential and commercial applications. Whether used in display cabinets, recessed lighting, or under-cabinet fixtures, the G4 socket plays a crucial role in enhancing lighting experiences while ensuring energy efficiency.
