25 M5 Warm White Twinkle Commercial Co-Axial LED Christmas Lights, 4" Spacing, Green Wire [CLOSEOUT]

Professional-grade warm white twinkle for permanent and semi-permanent installations — our warm white twinkle M5 Commercial Co-Axial LED Christmas lights deliver classic mini light warmth with an organic twinkle effect on every fifth bulb, built for commercial installers and serious residential decorators who need long-run reliability.

Built to a higher commercial standard — these strings use heavy-duty 20-gauge green wire and a proprietary 2-pin co-axial screw-on connector system that creates an extremely moisture-resistant connection between strings. Each string includes both a male and female co-axial connector, ships without a standard plug, and is designed to be connected directly into a commercial wiring run. A compatible co-axial male plug (sold separately) is required to power the first string in a run.

Frequently Asked Questions

Does this string include a plug?
No — commercial co-axial strings ship without a standard plug. A compatible co-axial male plug (sold separately) is required to power the first string in your run. Additional strings connect directly to each other using the built-in co-axial connectors.

How does the twinkle effect work?
Every fifth bulb is a twinkle bulb that turns on and off at random intervals, while the other four bulbs remain steady — creating an organic, natural-looking sparkle across the entire string.

How many strings can be connected end-to-end?
Up to 60 strings can be connected end-to-end — significantly more than standard consumer strings — making these ideal for large trees, long garland runs, and commercial-scale installations.
