Turning on your lights hands free, using just your voice.

If you have an Amazon Echo, you can control this bulb by Alexa. We has two lines of smart bulbs you can chose from. There's a handful of Bluetooth-based bulbs that use a Bluethooth mesh network to get going. These work with Alexa and will plug into your Amazon-powered smart home. There's also a line of Zigbee bulbs which will see you needing a hub.

"Alexa, turn on the lights."
