5mm LED Christmas Light Strings

5mm LED Christmas light strings from The Christmas Light Emporium are the go-to format for Christmas trees, wreaths, garlands, and bushes — available in steady-on single colors, exclusive ColorSplash blends, specialty effect lines, and app-controlled RGB.

What's in This Collection

Steady-On Strings — Single-color strings in warm white, cool white, red, green, blue, orange, purple, pink, teal, and gold. Multi-color combinations also available (red + green, red + cool white, blue + cool white, and more). Available in 35, 50, 70, and 100 count with 4" lens spacing, in green or white wire.

ColorSplash — Exclusive multi-color blend combinations available only at The Christmas Light Emporium. Blends include Arctic (Teal, Blue, Cool White), Stardust (Teal, Blue, Purple), Champagne (Warm White, Pure White, Cool White), Holly (Green, Red, Frosted Lime Green), and many more — including seasonal and novelty blends. Available in 50 count with 6" spacing. ColorSplash Magic and ColorSplash Treasure are hybrid strings that combine ColorSplash color blends with unique built-in fading and morphing effects.

DreamSpark® — Slow Fade — Each lens fades in and out independently at a random interval, creating a soft, organic, living glow. Available in single colors and ColorSplash blends, 70 count, 4" spacing. DreamSpark net lights also in this collection.

SuperSpark® — All-Strobe — Every lens on the string strobes continuously. Maximum visual impact and movement. Available in select colors, 50 and 100 count, 6" spacing.

QuadSpark® — Every 4th lens strobes; the other three are steady-on in the same color. A subtler strobe effect than SuperSpark® — movement without overwhelming flash. Available in select colors, 50 and 100 count, 6" spacing.

Dazzle™ — Every 4th lens is a cool white strobe; the other three are steady-on in the main color. Available in select color combinations, 50 count, 6" spacing.

Twinkle — Each lens blinks on and off independently at random intervals, creating a continuous organic twinkle across the full string. Available in warm white and cool white, 70 count, 4" spacing.

Twinkly — App-Controlled RGB — Individually addressable app-controlled RGB lights — every lens can display any color, and the Twinkly app lets you program custom animations, scenes, and effects. The only app-controlled programmable RGB string lights we carry. If you're searching for RGB Christmas lights, this is them.

5mm Net Lights — 4'×6' net lights in single colors and ColorSplash blends, including DreamSpark slow fade versions. For fast, even coverage over bushes and ground features.

Color Range

Warm white, cool white, red, green, blue, orange, purple, pink, teal, gold, multicolor, and ColorSplash blends. Not every effect line is available in every color — check individual product pages.
