What is Bulb Base
A bulb base, also known as a socket or connector, is an essential component of a light bulb that enables it to connect to a power source and establish an electrical connection. It is located at the bottom part of the bulb and is responsible for securing the bulb in place within a socket or fixture. The bulb base comes in various types and sizes, each designed for specific applications.
Common types of bulb bases include screw bases and pin bases. Screw bases, such as the Edison base, are widely used and come in different sizes denoted by descriptive names and numbers. These sizes indicate the diameter of the base in millimeters. On the other hand, pin bases, like the bi-pin base, consist of two pins that protrude from the base and are inserted into corresponding sockets.

常見問題
Is A19 a Standard Bulb
Shaped like a snow cone, LED A19 bulbs are commonly recognized as the traditional light bulb shape. These bulbs have become widely adopted as the standard for household lighting in various areas such as living rooms and bedrooms.
What Is an A15 Bulb Base
Another popular type of A-series light bulb is the A15 bulb, which is frequently utilized in the United States for appliances and ceiling fans. The A15 bulb has a width of 15⁄8 inches (17⁄8 inches; 48 mm) at its widest point and stands at a height of 3.39 inches.
Why Do LED Light Bulbs Not Work in Some Fixtures
Reasons for LED light bulbs not functioning properly in certain fixtures can vary. Some common causes include a defective power supply, loose connections, a flawed circuit design, or even damage caused by water infiltration from rain. Regardless of the specific cause or any noticeable indicators, there is typically a solution available to address the problem.
What Are the Two Types of Bulb Bases
Normally, a bulb typically has two types of bases: a screw base or a bayonet base. The diameter of the base is measured for bulbs with a screw base, while the spacing between two pins is measured for bulbs with a pin base.
How Do You Identify a Bulb Base
The shape or form of the bulb base is indicated by the first letter, while the width of the base is represented by the number, usually in millimeters. For instance, our 11S14 bulb is equipped with an E26 base, where “E” signifies the Edison screw-in style and 26 denotes a base width of 26 mm.
What Is an E26 Light Bulb Base
The E26 light bulb base is the cap or base of a light bulb that enables both electrical and mechanical contact. The term “E” in E26 stands for Edison Screw, which is the most common type of lamp base. The number “26” represents the diameter of the base in millimeters, which is approximately 1 inch.
What Is E26 vs E27 vs A19
E27 (or E26 in the USA) refers to the size of the socket screw base, commonly known as a medium base. A19, on the other hand, represents the standard shape of an indoor light bulb. Additionally, there is a BR30 bulb shape available, which is designed to fit into standard ceiling can fixtures and also features the E26 medium base.
What Is A19 Bulb Size
An A19 light bulb has a diameter of 19/8″ or 2.375 inches. To determine the size of a light bulb, refer to the full size scale provided, which is calibrated in eighths.
