E12 is a term commonly used in lighting to refer to a specific type of bulb socket. It is a designation used to describe the base of the bulb, which is the part that connects to the light fixture. E12 sockets have a diameter of 12 millimeters, which is smaller than the more common E26 socket, which has a diameter of 26 millimeters.
The "E" in E12 stands for "Edison," which is the name of the man who invented the incandescent light bulb. The number "12" refers to the diameter of the base in millimeters. E12 sockets are often used for smaller bulbs, such as candelabra bulbs, which are typically found in chandeliers or decorative fixtures.
E12 bulbs come in a variety of shapes and styles, including candle, torpedo, and globe shapes. They also come in a range of wattage options, from as low as 5 watts to as high as 60 watts. When replacing a bulb with an E12 base, it is important to ensure that you match the wattage and shape of the old bulb to the new one to ensure compatibility with the fixture.
In addition to E12, there are other common bulb socket types, including E26, E27, and GU10. E26, as mentioned earlier, has a larger diameter than E12 and is used for standard light bulbs. E27 is similar to E26 but is used more commonly outside of North America. GU10, on the other hand, is a type of socket used for twist-lock halogen bulbs.
Overall, E12 is a specific designation used to describe a type of bulb socket with a diameter of 12 millimeters. It is commonly used for smaller bulbs, such as candelabra bulbs, and can be found in a variety of shapes and wattages. When replacing bulbs with an E12 base, it is important to match the wattage and shape to ensure proper compatibility with the fixture.
