I have an older fixture in my dining room. What type of bulb is best to replace the traditional incandescent?

While traditional <a href="https://www.homedepot.com/b/Lighting-Light-Bulbs/Incandescent/N-5yc1vZbmbuZ1z0vxiy?emt=plpfaq_2504_lightbulbs" style="text-decoration: underline;">incandescent bulbs</a> provide a warm light, <a href="https://www.homedepot.com/b/Lighting-Light-Bulbs/LED/N-5yc1vZbmbuZ1z0vxij?emt=plpfaq_2504_lightbulbs" style="text-decoration: underline;">LED</a> or even <a href="https://www.homedepot.com/b/Lighting-Light-Bulbs/Halogen/N-5yc1vZbmbuZ1z0vxiw?emt=plpfaq_2504_lightbulbs" style="text-decoration: underline;">halogen</a> options are great for energy-efficient replacements; be sure to check the base type and wattage for compatibility with your existing fixture. These replacements will also last significantly longer.

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.

Which features should I look for when purchasing light bulbs?

There are many different features that will elevate your lighting, including <a href="https://www.homedepot.com/b/Lighting-Light-Bulbs/No-Color/Dimmable/40-Watt/N-5yc1vZbmbuZ1z0u4xvZ1z1u6h4Z1z21k9d?emt=plpfaq_2504_lightbulbs" style="text-decoration: underline;">dimmable</a>, <a href="https://www.homedepot.com/b/Lighting-Light-Bulbs/No-Color/Ceiling-Fan-Rated/40-Watt/N-5yc1vZbmbuZ1z17iblZ1z1u6h4Z1z21k9d?emt=plpfaq_2504_lightbulbs" style="text-decoration: underline;">ceiling fan rated</a>, and <a href="https://www.homedepot.com/b/Lighting-Light-Bulbs/No-Color/Energy-Saving/40-Watt/N-5yc1vZbmbuZ1z0u085Z1z1u6h4Z1z21k9d?emt=plpfaq_2504_lightbulbs" style="text-decoration: underline;">energy saving</a>.

When should I choose flood or spotlight bulbs, and what's the difference?

<a href="https://www.homedepot.com/b/Lighting-Light-Bulbs-Flood-and-Spot-Light-Bulbs/N-5yc1vZ2fkpcw3?catStyle=ShowProducts?emt=plpfaq_2504_lightbulbs" style="text-decoration: underline;">Flood light bulbs</a> produce a wide beam, ideal for illuminating large areas like patios or driveways. In contrast, spotlight bulbs focus their beam more narrowly, making them perfect for highlighting artwork or architectural features, giving you options for different needs and purposes. Both can be used indoors or outdoors, depending on the fixture.
