When thinking about the image of a typical bulb, most people envision that a light bulb that many of us have used since childhood is the traditional A bulb. However, the light bulbs have been significantly developed and now they are quite diverse with many types divided by shape and size. Of course, such a variety of shapes and sizes can be not only overwhelming but even confusing.
For example, it is often assumed that E12 and B11 are the two basic types of bulbs and one has to choose them. Currently, on the market, you can find a light bulb with both E12 and B11 in its description. How?
It can be seen that the E12 vs B11 are two different specifications and they can be found on the same bulb. This is easy to confuse and confuse consumers when choosing the desired product.
E12 vs B11 Codes Explained
A torpedo or flame shape light bulb (B11 shape) with a candelabra base (E12 base)
Similar to the shape of a candle, chandeliers are the modern solution for decorative lighting equipment. The shape of the chandelier is defined in terms of code.
With a number of different types of chandelier bulbs available, the most common starts with the following letters as a prefix. For example:
- B – Ammo or “Torpedo”
- C – Candle or “Cone”
- CA – Candle corner
- F – Flame style
To determine the basis of the size of the chandelier, two variables of the code are designated to be considered. The letter “E” refers to the basis of the “Edison” type, and the following numeric value represents the diameter in millimeters.
With two abbreviations, it can be confusing for customers to choose from.
The B11 bulb simulates the shape of a candle and comes in a variety of warm antique finishes.
E12 describes the base type of the bulb and is the Edison screw base of the lampstand.
E12 helps you decide which bulb base will fit with the socket your fixture has and after that, B11 helps you to choose the desired bulb shape.
As mentioned, the symbol E12 denotes the shape of the base, which helps you identify it from other types of soles. B11 indicates the shape of the light bulb, to avoid confusion when shopping.
Confusion often arises because these two codes and descriptions are usually found in the SAME bulb. Hopefully, the research and research of Laokoon Lamp will help partly to reduce the confusion when choosing.
