The world of light bulbs can be confusing, especially when it comes to the various base sizes available. Choosing the correct base size is essential for a seamless fit in your existing fixtures. In this article, we will explore the different base sizes for light bulbs that are commonly used in homes and businesses.
Common Light Bulb Base Sizes
1. E26 (Medium): The E26 base is the most common light bulb base in North America. This screw-in base measures approximately 26mm in diameter and fits a variety of fixtures.
2. E12 (Candelabra): The E12 base, often referred to as the candelabra base, is smaller, measuring 12mm in diameter. It is typically used in decorative lights, chandeliers, and some table lamps.
3. E14 (Small Edison Screw): The E14 base is slightly larger than the E12 at 14mm and is commonly used in Europe. It’s ideal for smaller lamps and fixtures.
4. GU10: The GU10 base features two pins and is primarily used for halogen and LED spotlights. The pins are spaced 10mm apart, which makes it distinct in appearance compared to screw bases.
