Light Bulb Size Guide: Understanding Light Bulb Bases
When browsing our website, you may have noticed an array of letters and numbers next to the light bulbs, cords, and sockets we carry. These identifiers can make light bulbs seem very complicated, but they are actually quite simple. To help clear up any confusion, the Paper Lantern Store is happy to offer a primer on light-bulb base sizes.
Understanding Light Bulb Base Sizes
To determine the correct light bulb base size, you first need to understand the naming system. There are many light bulb base sizes, but the three most common screw-in bases, known as Edison bases (named after Thomas Edison), are E12, E17, and E26. The "E" stands for Edison, while the numbers indicate the width of the light bulb base in millimeters. For example, an E17 base measures 17 mm in diameter.
Common Light Bulb Codes Explained
Aside from the base size, you might see other combinations of letters and numbers on light bulbs. For instance, a bulb labeled A60 has a specific shape and size. The letter "A" refers to its shape (A-shaped for general service bulbs), while "60" indicates the bulb's diameter in millimeters. Thus, an A60 light bulb with an E26 base would be a standard 60 mm bulb with a 26 mm Edison screw-in base, commonly used in households.
