What is Edison Base

Edison base is a standard-sized light bulb base commonly used in the lighting industry. It is named after Thomas Alva Edison, the renowned American inventor who popularized the use of electric light bulbs. The Edison Base, also known as an “E” style base, features a right-hand threaded aluminum or metal-capped base that screws into matching threaded sockets.

The most common type of Edison Base is designated as E26, which stands for 26 millimeters in diameter. This size is widely used in North America and is often referred to as a “Medium Screw” or “Standard Screw” base. It is important to note that the E26 designation is based on the diameter of the base in millimeters. In addition to the E26 base, there are other variations of the Edison Base used in the lighting industry. These include the Candelabra Screw (E12), Intermediate Screw (E17), and Mogul Screw (E39) bases, each with different sizes and applications.

The Edison Base is compatible with various types of light bulbs, including incandescent, halogen, fluorescent, and LED bulbs. It is widely recognized and used in the industry, providing a reliable and standardized connection between light bulbs and sockets.
