The number 26 indicates the diameter of the light bulb base in millimeters – so you can see this would fit into a standard E26 socket.

For example, a T10 wedge base is commonly used in automotive taillights, while a T15 wedge base is used in some turn signal and brake light applications. The most common is the Edison screw base, which may be found on most incandescent bulbs and many halogens, compact fluorescents, HIDs, and now LED lights.

The name “Exx” is made up of the letters “E” for “Edison” and “xx” for the millimeter diameter measured across the peaks of the thread on the base (male). Luckily, there are standards for light bulb base sizes in the lighting industry, and parts are made to meet those standards. This is why light bulb bases aren’t standardized: if they were interchangeable across light fixtures, people would risk inserting a light bulb into sockets that weren’t designed for them. Medium bi-pin sockets are generally used in a variety of linear fluorescent bulbs, like the T8 and T10 lights. In most cases, when bulbs are powered by alternating current, the thread is linked to neutral, and the contact on the bottom tip of the base is connected to the “live” phase.

Wedge bases are a type of electrical connector that are commonly used in automotive lighting and other applications. The type of socket dictates how much power you can safely put through it without overloading or shorting out your home’s wiring. This design allows the connection to be made and broken quickly and easily, while also providing a secure connection. They are commonly used in various applications, such as lighting, electrical power distribution, and telecommunications. The letter “E” in E26 refers to Edison Screw, the most standard of lamp bases, while the numerical “26” refers to its diameter in millimeters (approximately 1 inch).You can simply replace your existing lamps or upgrade to the latest versions if you're feeling green. These are used with compact fluorescent tubes that plug into a light fixture that has a permanent ballast. Twist-lock 120/230- volt MR16 halogen lighting of 35/50 watt, differs from GU10 by use of a dichroic reflector. A lowercase "q" at the end of the designation indicates that it is a quad-pin base, with two bi-pin pairs.

The Edison screw (ES) is a type of light bulb base that is universally used with electric light bulbs.E-10 base light bulbs have a single contact on the bottom and are used in flashlights, indicators, and toys.

Like candelabra bulbs with E12 bases, bulbs with E17 bases are used for decorative applications, such as chandeliers, wall sconces, Christmas lights, restaurant pendant lights, ornamental lights, and sign or marquee lights. Here is a light bulb base chart that includes pictures of conventional light bulb bases, such as fluorescent bases, LED light bases, automotive light bulb bases, halogen bases, etc. In the early days of electricity, the only standard connector was an Edison screw, and all appliances except light bulbs were hooked up to AC power through lamp sockets. When you’re wondering what the difference between a medium and a miniature bi-pin socket is, it doesn’t just involve the size of the part itself. Light fixture sockets have a grip on the inside of the socket, and light bulb bases have a matching metal tab on the outside of the base.

In North America, there are three different types of electrical outlets: A-type, B-Type, and C-Type sockets. The bulbs have metal bases (caps) that are threaded in the right direction and screwed into matching threaded sockets (lamp holders). It is important to choose the right type of light bulb base for your specific application, as using the wrong base can cause problems such as flickering or improper electrical connections. The suffix after the G indicates the pin spread; the G dates to the use of Glass for the original bulbs. The base has two or more protruding tabs that fit into corresponding slots in the pin, and the pin is then rotated to lock the connection in place.
