Question 1

What are bi-pin and 4-pin bases, and what are they used for?

Accepted Answer

Bi-pin bases, including the miniature and medium bi-pin, have two small pins that push into a socket commonly used for halogen or some LED bulbs in undercabinet lighting or desk lamps. 4-pin bases, with their four pins, are often found in fluorescent and compact fluorescent (CFL) bulbs; they are designed for fixtures requiring a more secure connection and may need specific ballast compatibility.

Question 2

What's the proper way to dispose of old light bulbs?

Accepted Answer

To responsibly dispose of your old bulbs and find out which ones require special handling, read our How to Dispose of Light Bulbs guide. We want to help you stay safe and keep the environment healthy.

Question 3

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?

Accepted Answer

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 E26. 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.

Question 4

Does The Home Depot have different bulb shapes?

Accepted Answer

Yes! We offer a variety of bulb shapes, including specialty, tubular.

Question 5

Can I use universal light bulbs in any fixture in my home?

Accepted Answer

Universal light bulbs generally refer to bulbs designed for various applications and fixtures, meaning they're versatile for different settings. Always double-check your fixture's requirements to ensure the bulb's base, wattage, and voltage match; following the guidelines helps ensure safety and compatibility for any light fixture around the house.
