Twinkly is the revolutionary LED light string that brings the most advanced technology to your decorations. The RGB colors are highlighted by the special finish of the Twinkly lens—matte and flat—giving a uniform diffusion of the chromatic components without altering the expressive power.You can even create an individualized light spectacle through the Twinkly mobile app. Using your local Wi-Fi (or the Twinkly Integrated Wi-Fi), the app connects to the controller and can manage every single LED. The Twinkly app is connected to your smartphone camera and can make a map of the position of each LED, allowing you to create brand new effects and draw the animation you want for your lights, directly on your device. Please Note: The Add-On Set requires the Starter Light Set to work.
