Product Description Simply integrate Sengled Pulse Flex into your home Wi-Fi network. By using the free app you can dim the light and create individually controllable groups with multiple bulbs. The result is a multi-room environment in which you can play back several sources at the same time. You can easily start streaming music by using popular apps such as Spotify or Deezer and just switch it over to the bulbs. Your mobile is then free to use for whatever you wish. And to maximise the fun you can also use Pulse Flex in any E27 socket outdoors!
