Smart LED string lights

Twinkly Strings TWS400SPP-BEU Smart LED String, 400 RGBW LEDs, 32 m, Wi-Fi & Bluetooth, IP44

Every LED is addressed individually from the app, and the IP44 build takes it outdoors.

The Twinkly Strings TWS400SPP-BEU is a smart LED string with 400 addressable RGBW LEDs, each one individually colour-controlled from the mobile app. It offers a 32 m lighted length with 8 cm LED spacing, and its IP44 rating covers both indoor and outdoor use. Power comes from a 36 W (24 V) adapter with a Type F plug.

400 addressable RGBW LEDs with warm white

A four-channel light source adds a dedicated white LED to the RGB trio, so pure warm white looks like classic fairy lights rather than a mixed tone. The palette spans over 16 million colours, with each LED lit independently of its neighbour. The LEDs are 5 mm cylinders with a matte and clear finish.

Mapping with your phone camera

The Twinkly app captures the position of every LED on your decorated tree or façade in seconds, then treats the layout like a screen. Animations run in the right direction instead of blinking at random. Preset scenes are joined by new effects from the Twinkly Store, and the FX Wizard lets you draw your own.

Three strings act as one 1200-LED display

The app groups up to three 400-LED strings and drives them in sync, enough for a tall tree or a whole façade. Grouping also works with other Twinkly devices, and Twinkly Music makes the lights follow your tracks in real time.

Wi-Fi, Bluetooth and voice control

The Generation II controller pairs over Bluetooth for setup and runs over Wi-Fi on your home network, including timer and dimming. It works with Google Home, Amazon Alexa, Homey, Razer Chroma and OMEN Light Studio.

IP44 for terrace, garden and balcony

The string, the controller and the power supply all carry the same IP44 protection, so the whole run copes with rain and damp outdoors. LED life is rated at over 30,000 hours, and the 2.5 m lead cable to the first LED gives you room to reach a socket.
