Question 1

What's the difference between a medium (E26) and candelabra (E12) screw base, and which one do I need?

Accepted Answer

Medium (E26) base bulbs are the most common size for household lamps and fixtures, while candelabra (E12) bases are smaller and typically used in chandeliers, decorative fixtures, and nightlights. To choose the right one, look at the base of your old bulb or the fixture socket – if it's larger and standard-sized, you need an E26, while smaller ones are E12.

Question 2

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

Accepted Answer

Flood light bulbs 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.

Question 3

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 4

I want to upgrade to LED bulbs, but I'm unsure if the base will fit. What common base types might I encounter, and what should I consider?

Accepted Answer

Common bases for LED upgrades include the screw-in E26 (standard medium base), smaller E12 (candelabra), and bi-pin bases like GU10 or G4. When upgrading, always match your existing base code; however, some LEDs, such as the E26, are offered in other base types, such as the GU10, for use in many common fixtures. Be sure to double-check to ensure you select the correct base.
