B11 vs E12 – Which is The Best of Decorative Light Design?

When most people think of a light bulb, they usually think of the classic A bulb, which many of us have used since childhood. On the other hand, light bulbs have progressed substantially and now come in various shapes and sizes. Of course, such a wide range of forms and sizes can be bewildering, if not downright perplexing.

It is commonly considered, for example, that E12 and B11 are the two main types of bulbs from which one must pick. A light bulb with both E12 and B11 in its description can be found on the market. How?

The E12 vs B11 are two separate specs that can be found on the identical bulb, as can be seen. It’s easy to perplex customers when it comes to selecting the right product.

E12 Vs B11 Codes Explained

E12 Vs B11 Codes Explained

A light bulb with a torpedo or flame shape (B11 form) and a candelabra base (E12 base). Chandeliers, which resemble the shape of a candle, are the current answer to ornamental lighting equipment. A set of codes determines the chandelier’s shape.

There are many different types of chandelier bulbs available. However, the most popular begins with the letters listed below as a prefix. Consider the following scenario:

  • B – Ammo or “Torpedo”
  • C – Candle or “Cone”
  • CA – Candle Corner
  • F – Flame style

Two variables of the code are designated to be considered when determining the size of the chandelier. The letter “E” stands for the “Edison” type’s foundation, while the numeric value after it represents the diameter in millimeters.

Customers may find it difficult to pick between the two abbreviations. The B11 bulb has a candle-like shape and is available in several warm antique finishes. The Edison screw base of the lampstand is designated as E12, which identifies the bulb’s base type.

E12 assists you in determining which bulb base will fit the socket in your fixture, and then B11 assists you in selecting the correct bulb shape.

As previously stated, the symbol E12 specifies the base’s form, which aids in distinguishing it from other types of soles. To avoid confusion when buying, B11 denotes the form of the light bulb.
