Big bulbs. Big memories.
The overview

What it is, and why it matters.

C9 bulbs are the classic Christmas look: large, glowing and a little retro. They shine brighter than mini lights from the street and look fantastic on rooflines, along fences and on big trees.

We install C9 strands with purpose-made clips so every bulb faces forward and stays put. You choose warm white, multicolor, red and green or a mix, and we handle the wiring, power and testing.

Why people choose it

Four things done right.

Bright from the street

C9s carry glow across a wide yard so your display reads from the road.

Bulbs stay aligned

Clips hold each bulb upright and facing out for a clean, uniform line.

Power planned

We plan circuits and connections so the whole display runs reliably.

Colors that last

Quality LED bulbs keep their color through the season.

Good questions

C9 Bulb Installation: common questions

What is a C9 bulb?

It is the large, classic Christmas bulb about the size of a small fig. It gives the traditional glow and is the most popular bulb for rooflines.

Are C9 LEDs worth it?

Yes. LED C9s draw much less power than older bulbs, run cooler and keep their color, and they look just as classic from the street.
