What are Bayonet Bulbs?
Bayonet bulbs are a type of light bulb that uses a bayonet cap for connection. The bayonet cap features pins on opposite sides of the base that fit into slots in the socket, requiring a push-and-twist motion to secure the bulb. This mechanism provides a reliable and secure connection, preventing the bulb from coming loose.
Is B22 the Same as Bayonet?
Yes, B22 is a type of bayonet bulb. The "B" in B22 stands for bayonet, and the "22" refers to the diameter of the base in millimeters. B22 is one of the most common bayonet bases used in household lighting.
What is the Difference Between B22 and E27?
The main difference between B22 and E27 lies in their base types:
- B22: This is a bayonet cap with a 22mm diameter, requiring a push and twist motion to fit into the socket.
- E27: This is an Edison screw cap with a 27mm diameter, requiring a simple screwing motion to fit into the socket.
Both types serve the same function of connecting the bulb to the electrical supply but use different mechanisms for attachment.
Why Does the UK Use Bayonet Bulbs?
The UK uses bayonet bulbs due to historical and practical reasons. Bayonet fittings were widely adopted during the early electrification of homes in the UK and have remained popular due to their secure connection, which prevents the bulb from loosening over time. This preference has persisted through the years, and bayonet fittings are still commonly found in UK homes today.
Is My Bulb a B15 or B22?
To determine whether your bulb is a B15 or B22, you can check the diameter of the base:
- B15: This is a smaller bayonet cap with a 15mm diameter.
- B22: This is a larger bayonet cap with a 22mm diameter.
If you measure the base and it is 15mm, it is a B15. If it is 22mm, it is a B22.
How to Tell if Bayonet or Screw?
You can identify whether a bulb is bayonet or screw by examining the base:
- Bayonet (B type): Has two pins on opposite sides of the base. It fits into the socket with a push and twist motion.
- Screw (E type): Has a threaded base. It fits into the socket with a screwing motion.
Which is Better, a Screw or a Bayonet?
Both screw and bayonet bulbs have their advantages:
- Bayonet: Known for a secure connection, preventing the bulb from loosening. Common in regions like the UK.
- Screw: Easier to install and remove, widely used globally.
The choice between the two often comes down to regional preferences and the specific fixture in use.
Is B22 Being Phased Out?
There is no widespread initiative to phase out B22 bulbs. They remain popular in many regions, including the UK. However, with the global shift towards energy-efficient lighting and LED technology, the types of bulbs available may change, but the B22 fitting is likely to remain in use.
Why is it Called a Bayonet?
The bayonet cap is named after the bayonet weapon, which attaches using a similar mechanism. The push-and-twist motion used to secure a bayonet bulb resembles the method used to attach a bayonet to a rifle. This mechanism ensures a secure and reliable connection, which is why the name was adopted for this type of bulb fitting.
