I'm replacing a bulb and see a lot of letters and numbers on the base. What do these light bulb base codes like E26, GU10, or G13 mean?

Light bulb base codes indicate the type of connector and the size of the bulb's base, ensuring it fits correctly into your fixture. The “E” denotes a standard screw-in Edison base, like the common <a href="https://www.homedepot.com/b/Lighting-Light-Bulbs/E26/N-5yc1vZbmbuZ1z0tp3j?emt=plpfaq_2504_lightbulbs" style="text-decoration: underline;">E26</a>. At the same time, “GU” usually signifies a bi-pin connector often found in track lighting and spotlights, and “G” is usually the most popular of the common bi-pin base types. Understanding these codes prevents buying the wrong bulb and ensures safe, reliable lighting.
