What is E12 Bulb

An E12 bulb, also known as a candelabra bulb or Type B bulb, is a type of light bulb that features a base with an Edison screw fitting and a diameter of 12 millimeters. The designation “E12” signifies that it is part of the Edison bulb family, with the “E” representing Edison and the “12” indicating the diameter of the screw base in millimeters.

E12 bulbs are commonly utilized in smaller lighting fixtures such as candelabras and chandeliers. They are characterized by their compact size and lower wattage compared to other bulb types. Typically, E12 bulbs have a bullet or flame-shaped design, making them ideal for decorative purposes. These bulbs are often used to create an ambient or accent lighting effect in various settings.

E12 designation refers specifically to the screw base size and type, rather than the style or type of the bulb itself. This means that different types of bulbs, including incandescent, LED, and compact fluorescent bulbs, can be equipped with an E12 base.
