Bi-Pin - A-Style - Light Bulbs - The Home Depot

Question 1

Are tube lights only used in commercial settings, or can I use them at home?

Accepted Answer

While commonly used in garages and basements, tube lights, especially LED tube lights, are becoming increasingly popular for their energy efficiency and bright light in home workshops, under-cabinet lighting, and even for creating a modern, minimalist look in certain rooms. They offer a lot of options for different areas of the house.

Question 2

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 3

Question 4

What are type A light bulbs, and why are they so common?

Accepted Answer

Type A light bulbs are the classic, pear-shaped bulbs you're most likely familiar with. They fit standard medium-base sockets and are widely used in lamps and fixtures throughout homes. Their popularity stems from their versatility, affordability, and compatibility with most everyday lighting setups, making them a reliable choice for general illumination.
