Dazzling. Sparkling. Soft. Warm. Cool. White. Red. Green. Illuminating . . . light. The endless subject of poets and artists, it is also an essential element of any Christmas. And what does that Christmas light dance out from? Bulbs, of course! That’s why knowing some differences in your bulbs can be incredibly useful. And while it can all feel a bit technical at times, choosing the right bulb doesn’t need to be a frustrating or overwhelming affair. That’s why we’ve prepared a few helpful tips for choosing two of the most popular bulbs out there to help your holiday lighting shine – the popular and versatile C-7 and C-9 Christmas bulbs:

The C-7 Bulb with Candelabra E-12 Base:

The Basics: the C7-bulb has the E-12 Candelabra base, a smaller base and thus a smaller bulb. The C-7 is generally used to decorate smaller trees and decorative products, roofs, and building edges. They are LED and thus energy efficient, brighter, and cooler to touch.

Tip: the C7 bulbs can be used both outdoor and indoor, but are best used for décor products that will be seen up close by your customers and not by those that will be farther away.  They are also great if you want that “retro Christmas” light look.

The C-9 Bulb with Candelabra E-17 Base:

The Basics: The C-9 bulb with the Candelabra E-17 base is a bigger bulb with a bigger base. It is also LED. They are most often used to decorate much larger trees, buildings, venues, and outdoor décor. It is considered the “standard” go-to Christmas bulb for larger venues and decorations.

Tip: If you are planning to showcase your lights outside, have a large venue, or planning on utilizing some very large objects, then consider using the C-9. They are especially wonderful for very large trees due to their larger size.
