C9 LED Christmas Lights

C9 LEDs are the backbone of every professional roofline install. The big E17 base bulb that clients see from the street. This is what separates a pro job from a DIY disaster.

Why Contractors Choose C9s for Rooflines

C9 bulbs deliver the visibility and impact that residential and commercial rooflines demand. They punch through at 100+ feet. Clients notice the difference immediately compared to smaller bulbs.

We stock Minleon, Tough Bulb, and Opti-Core. Three brands that professional installers trust season after season. Each one passes our quality standards before it hits the shelf.

Available Styles

  • Faceted. Diamond-cut lens that catches light from every angle. The most popular finish for roofline work.
  • Filament. Vintage warm glow with visible curved filaments. Premium look for upscale installs.
  • Smooth Opaque. Bold even color with a clean traditional finish.
  • Shatterproof. Polycarbonate lenses that survive job-site drops and commercial abuse.
  • Twinkle. Random flash effect for dynamic sparkle mixed into steady runs.

Built for the Job

Every C9 we sell is commercial-grade LED. That means rated for 25,000+ hours, energy efficient, and cool to the touch. No fire risk on shingles or gutters.

Need the full setup? Grab a C9 Pro Light Kit with bulbs, socket wire, clips, and plugs bundled at contractor pricing. Jason Geiman has tested every product we stock on real rooflines across thousands of installs through his contractor network.

Frequently Asked Questions

What wattage are C9 LED bulbs?

C9 LEDs pull between 0.5W and 0.96W depending on brand and style. That is a fraction of the 7W a traditional incandescent C9 draws. Lower wattage means longer runs, fewer circuits, and zero fire risk on shingles.

How many C9 LED bulbs can I run on one circuit?

With LEDs pulling under 1W each, you can run 800+ C9 bulbs on a single 15-amp circuit. Compare that to roughly 200 incandescent C9s on the same circuit. LEDs let you cover entire properties from one or two outlets.

What spacing should I use for C9 bulbs on rooflines?

12-inch spacing is the standard for residential rooflines. It gives a full, professional look without gaps. For commercial buildings with higher rooflines and longer viewing distances, 15-inch spacing works well and saves material cost.

What is the difference between C9 faceted, smooth, and filament bulbs?

Faceted C9s have a diamond-cut lens that catches light at every angle. Best seller for rooflines. Smooth opaque C9s give a bold, even glow with a classic look. Filament C9s have visible curved filaments for a vintage warm aesthetic. Check our faceted, smooth, and filament sub-collections to compare.

Are C9 LED bulbs compatible with existing socket wire?

Yes. C9 LEDs use the standard E17 base that fits all C9 socket wire. Drop them into your existing stringers or grab new C9 socket wire for fresh installs.
