Outdoor ambiance I appreciate functional outdoor lighting that ensures I don't trip in the dark. But sometimes I also want a touch of glamour. These Nanoleaf String Lights offer a bit of both. Hang them above your patio, deck, or any other spot you need some added ambiance. Each faceted bulb can be individually controlled for a rainbow of color. Control it any way you want You can use the free Nanoleaf app to control the string light's functions via Bluetooth or Wi-Fi. Turn it on or off, adjust the brightness and color, group lights, and play scenes. If you have a Matter-compatible smart home hub (a.k.a. "Matter controller"), you can unlock its full potential - create lighting schedules and operate your lights when you're not at home. You can also adjust your lighting system hands-free if you've got a voice assistant. It works with Siri, Alexa, and Google Assistant devices (sold separately). This string light also includes an inline controller that lets you make app-free adjustments. Change the brightness, turn it on or off, or cycle through color options without ever pulling out your phone. Cover more ground You can add one or two expansion packs , depending on which base kit you purchased, up to a total of 147 feet. What's in the Box: 1.
