Get ready to illuminate your knowledge and brighten your choices!

What Is A Fitting?

Do you know what a fitting is? It’s an important part of any light bulb. Let me explain it to you in simple terms. A light bulb has two main parts: the bulb itself, which produces the light, and the mount, which connects the bulb to the socket. The mount and the socket together are called the fitting. The fitting has two main functions: it provides electricity to the bulb, and it allows you to replace the bulb easily and safely.

There are many different types of fittings, and each one has a unique code that tells you its shape and size. The code consists of a letter and a number. The letter stands for the name of the fitting, and the number is the diameter of the fitting in millimetres. For example, an E27 fitting is an Edison Screw fitting with a diameter of 27 millimetres. You can find the code on the packaging of the bulb or on the base of the bulb itself.

Some of the most common types of fittings are:

  • Bayonet Caps (BC): These are the ones that you twist and lock into place. They are very popular in the UK and have a code of B22 or B15, depending on the size. They are used for ceiling lights, table lamps, and wall lights.
  • Edison Screw (ES): These are the ones that you screw into the socket. They are more common in Europe and have a code of E27 or E14, depending on the size. They are used for decorative lamps, chandeliers, and feature lights.
  • GU10 and GU5.3: These are the ones that you push and twist into the socket. They have two pins on the base and a code of GU10 or GU5.3, depending on the distance between the pins. They are used for spotlights and downlights, such as the ones in your kitchen or bathroom.

Bayonet Mount (B22)

Hi there, do you know what a bayonet mount (B22) is? It’s a type of light bulb fitting that you can find in many homes in the UK and other countries that used to be part of the British Empire, such as Australia, India and Pakistan. It’s very easy to use, you just need to push the bulb into the socket and twist it slightly to lock it in place.

The name “bayonet” comes from the way the fitting looks like a bayonet, which is a knife or a sword that soldiers attach to the end of their rifles. The bayonet mount was invented in the late 1800s, and it was originally designed for this purpose.

The bayonet mount has a code that tells you the size of the fitting. The code starts with the letter “B” and then a number. The number is the diameter of the base of the bulb in millimetres. For example, the B22 bayonet mount has a base that is 22mm wide.

The bayonet mount has two parts: the bulb and the socket. The bulb has two metal contacts with bayonets on either side, and the socket has two L-shaped slots with springs. The bulb and the socket fit together with a push and twist action. The springs keep the bulb in place and prevent it from falling out.

Edison Screw (E27, E14)

Do you know what kind of light bulb socket you have in your home? If you live in the UK or continental Europe, chances are it’s an Edison screw, also known as E27. This is a standard type of socket that was invented by Thomas Edison in 1909 and trademarked under his Mazda brand. 

Edison screw bulbs have a metal base that screws into a matching socket, which has a threaded metal ring. The metal base and ring act as electrical contacts that connect the bulb to the power supply. The socket is usually inserted into a lamp holder or fixture, which holds the bulb in place and provides additional protection.

The diameter of the socket is indicated by a letter followed by a number, such as E27 or E14. The letter stands for Edison screw, and the number stands for the millimetres across the socket. So, an E27 socket has 27mm across, while an E14 socket has 14mm across.

Edison screw bulbs are very common and versatile, as they can be used with different types of lamps and fixtures. They are also easy to replace, as they can be unscrewed from either end of the socket. However, they are not very energy-efficient compared to other types of bulbs, such as LED or CFL, which use less electricity and last longer.


If you are looking for a way to brighten up your home or office, you might want to consider using bi-pin light bulbs. These are small bulbs that have two pins at the base, which fit into a socket or a fixture. They come in different types and sizes, depending on your needs and preferences.

One of the most common types of bi-pin light bulbs is the MR16, which stands for multifaceted reflector. This bulb has a shiny surface that reflects the light in a narrow beam, making it ideal for spotlighting or accent lighting. MR16 bulbs work with low voltage, so they need a transformer to convert the mains power. They have two pins that plug into the socket without twisting.

Another popular type of bi-pin light bulb is the GU10, which is a newer version of the MR16. It was developed by Havels-Sylvania in 1996, and it has some advantages over the MR16. For one thing, it runs on mains voltage, so it doesn’t need a transformer. It also has a twist-lock mechanism that secures the bulb in place. 

G9 and G4 are two other types of bi-pin light bulbs that operate at 12V. They are mostly used in household appliances, such as microwaves, ovens, and refrigerators. They have two straight pins that insert into the socket. They are very small and compact, but they can produce a lot of light.

All these types of bi-pin light bulbs are available in LED versions, which are much more energy-efficient and long-lasting than halogen or incandescent bulbs. LED bulbs use up to 90% less energy than halogen bulbs, and they can last up to 50,000 hours, compared to 1,000 hours for incandescent bulbs and 10,000 hours for fluorescent bulbs. LED bulbs also emit less heat and have a better colour rendering index (CRI), which means they show the true colours of objects and environments.
