EXTEND THE GLOW
Extend your outdoor LED string lights up to 72 ft with this 24ft add-on set. Built for existing LIFX string light setups, it joins seamlessly onto your starter kit and carries the same three color zones per bulb for rolling rainbows, sunset fades, or icy white flows. Requires an existing LIFX Outdoor String Light starter set. No bridge, no hub, just Wi-Fi (2.4GHz). Schedule it, build routines, or run a preset to keep the whole run in sync.
- IP66 rated, weather-ready, and runs without a hub or a bridge in sight.
- 16 million colors and tunable whites, controlled from the app, by voice, or on a schedule that runs itself.
- Extends with LIFX String Light Extensions up to 72ft to cover patios, pergolas, fences, or the whole backyard.

Everything you need is in the box. Screw it in, plug it in, or wire it in. Open the app, follow the prompts. No hub, no complicated setup, no reading the manual twice.

Set the vibe.
Tap any of the preloaded themes. Pick a wake-up time. Done. You can stop here forever, or build whatever you like and save your vibe as a Scene.
