Everything You Need to Know About Commercial Co-Axial LED Christmas Light Strings

Commercial co-axial LED Christmas light strings are built on heavier 20 AWG wire — versus the standard 22 AWG used in most residential strings. The heavier wire supports longer runs, higher load capacities, and more demanding installation environments. The co-axial connector system allows multiple strings, spacers, and power taps to be combined into a single continuous run with centralized power management.

What’s in This Collection

Co-Axial 5mm Strings — 5mm wide-angle dome lens. Available in warm white, cool white, red, green, blue, and multicolor. 4” spacing, green wire, 20 AWG.

Spacer/Extension Cables — For adding distance between strings in a run, or bridging gaps between sections. Available in multiple lengths.

Male Plug — For the power-source end of a co-axial run.

Power Tap Y / T / X — Power distribution taps for splitting and routing power to multiple branches of a co-axial run from a single power source.

Co-Axial vs. Standard Strings

Standard residential strings use 22 AWG wire. Co-axial strings use 20 AWG wire with a co-axial connector system — allowing longer continuous runs and centralized power management without the end-to-end connection limits of standard strings. The correct choice for large commercial installations, mega trees, and high-density display builds.

How to Choose

These commercial-grade strings use a coaxial construction for consistent spacing and increased durability, making them well suited for professional installations and large-scale displays. M5 strings feature an elongated faceted lens that delivers the classic incandescent silhouette; 5mm strings use a wide-angle dome lens for maximum light spread coverage. Choose M5 for a traditional look or 5mm for broad output, and match the string length to your installation run.

Frequently Asked Questions

Are co-axial strings compatible with standard string connectors? No — co-axial strings use a proprietary connector system. All components in a co-axial run must be co-axial format.

Are co-axial strings dimmable? Refer to individual product pages for dimmability information.

What’s the Reindeer Proof™ Warranty? Our in-house warranty covering manufacturing defects and performance failures. Duration varies — see individual product pages.

Are co-axial strings compatible with standard Christmas light accessories?

Co-axial strings use a proprietary connector system that differs from standard SPT socket wire. They are not interchangeable with standard C7/C9 stringer wire or standard SPT accessories. Use only co-axial-compatible connectors and accessories with co-axial string systems.
