Question 1

What are twist & lock and bayonet bases, and how are they different from screw-in bases?

Accepted Answer

Twist & lock bases, often seen in recessed lighting and some outdoor fixtures, don't screw in but instead lock into place by inserting and turning. bayonet bases, recognized by their cylindrical shape and side pins, are commonly used in older fixtures and some specialty appliances. They don't use the traditional threaded screw-in design, so check the fixture before purchase.

Question 2

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.

Question 3

I'm planning a party. Is it safe to use colored light bulbs in regular fixtures, or are there specific concerns?

Accepted Answer

Colored light bulbs are safe in standard light fixtures, adding a fun and festive atmosphere to any event. Just match the bulb base type and wattage to your fixtures.

Question 4

I'm looking for a tubular bulb for my fixture, and I see "T8," "T5," and "T12" listed. What do these "T" numbers mean, and how do they differ?

Accepted Answer

The "T" in these codes indicates a tubular shape, often used for fluorescent or LED tubes, and the number represents the tube diameter in eighths of an inch; thus, a T8 bulb is 1 inch in diameter, while a T5 bulb is 5/8 of an inch, and a T12 is 12/8 of an inch (or 1.5 inches), with the smaller diameter often correlating to newer, more energy-efficient models. Choose the correct number that matches the socket in your fixture.

Question 5

There are so many types of light bulbs! How do I choose the right one?

Accepted Answer

From LEDs to incandescents and everything in between, each bulb type has its own benefits. Not sure where to start? Our Types of Light Bulbs guide breaks down the different kinds, explaining their energy efficiency, lifespan, and best uses, making it simple to find the perfect fit.

Question 6

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.
