Types of Lamp Sockets

A Simple Guide to Lamp Sockets: What You Need to Know

Lamps do more than just light up a room — they add style and help create the mood of a space. One small but important part of any lamp is the socket, and you might be surprised by how many different types there are. In this blog, we’ll take a closer look at lamp sockets and help you choose the right one for your lighting project.

The Different Types of Lamp Sockets

Lamp sockets come in all shapes and sizes. Each one is made to fit a specific kind of light bulb. Here are some of the most common types:

1. Edison Screw (E26/E27): The most common socket type — E26 is standard in North America, and E27 is used across Europe.

2. Candelabra Base (E12): A smaller socket, often found in chandeliers and decorative lights.

3. Intermediate Base (E17): Slightly larger than E12, used for certain decorative or small appliance bulbs.

4. Bayonet Cap (B22 or BC): Popular in the UK — bulbs twist and lock into place, rather than screw in.

5. GU10 / GU5.3: These are pin-type sockets used in spotlights, especially with halogen and LED bulbs.

6. G4 / G9: Small two-pin sockets for compact halogen or LED lights.

7. T5 / T8 / T12: Used for fluorescent tube lights, these come in different lengths and thicknesses.

8. Mogul Base (E39/E40): A larger socket used for high-power bulbs and specialist lighting.

9. Miniature Screw (E10): Very small — often used in torches or mini lights.

10. Medium Bi-Pin (G13): Common for fluorescent tube lamps.

11. R7s: Used for linear halogen bulbs, often found in floodlights.

12. Bipin Bases (G4, G5.3, G8, G9, G12): For a variety of spotlight and task lighting bulbs.

13. Screw Terminals: These are used for hardwired connections in some special lamps or fixtures.

How to Choose the Right Lamp Socket

Picking the correct socket is important for both safety and functionality. Here’s how to choose the right one:

1. Know Your Bulb: Find out what kind of bulb you’re using — this will help you match it to the correct socket.

2. Check Your Fixture: Most lamps or fittings will state which socket type they use. Look at the label or product description.

3. Think About Power: Make sure the socket can handle the wattage of your bulb. Using a bulb that’s too powerful can be a fire risk.

4. Match the Base: The base of the bulb must fit the socket. For example, an E27 bulb needs an E27 socket.

5. Consider the Look: Some sockets are visible in the design — choose one that matches your interior style if it will be seen.

6. Ask for Help: If you’re unsure, speak to a lighting expert or contact us for advice — we’re happy to help.
