There are a few things you should think about while examining the different bulb kinds. It's crucial to understand the various LED bulb base types when purchasing the appropriate light for your fixture to make sure you receive the proper one. The most important kinds of LED bulb bases are shown below.
Edison
This variety, which has a fitting name, is shaped like the common light bulb that Thomas Edison is usually associated with. These are the most widely utilized kinds of LED lighting in both homes and businesses. When purchasing this kind of bulb, you will see that each variety has a unique illustration. The following number indicates the base's width in millimeters, and the E stands for Edison. You may pick the proper bulb by comprehending these numbers. The following are the most common denotations you will see:
E12 = Candelabra base
E14 = Small Edison Screw base
E17 = Intermediate base
E26 = Medium base
E39 = Mogul base
Bi-pin
The term "bi-pin" means precisely what it says. It is a lamp with two pins at the base as opposed to the more conventional screw-in type. A bi-pin lamp type will have a number that, like the Edison denotations, enables you to determine if it is appropriate for your fixture. They are identified by the letters G followed by a number that specifies the distance between the pins, for example, GU5.3 and GU10. Even though all pin lights are grouped under the bi-pin category for LEDs, a lamp might have more than two ins. Options with letters such as S for single pin, D for double pin, T for triple pin, and Q for quadruple pin are a few typical variants you could encounter.
Bayonet
Although the two most popular bases for LED bulbs are Edison and bi-pin, bayonet is still a viable alternative for certain bulb types. Two notes on the side of a bayonet bulb secure the bulb in the lamp or socket. Depending on how many contact points exist at the end of the bulb to connect to electricity, they are either single contact (SC) or double contact (DC).
