Twinkly Strings 400 RGB LED Smart String Lights

Twinkly turned string lights into a display. The app uses the phone camera to map every one of the 400 LEDs on the tree or wall, then plays animated effects, gradients and even uploaded images across them in the right positions.

The lights work with Wi-Fi and Bluetooth, sync to music with an optional accessory, integrate with Alexa and Google and are rated for indoor and outdoor use. The string is 105 feet long with a 10-foot lead.

Plug into a standard outlet; control with the Twinkly app.
