Nanoleaf's been making 3D-printed LED light bulbs with the light-emitting diodes on the outside for a few years now, but now, they're releasing a connected version of that same design -- and it'll work directly with Apple HomeKit.
In addition to controlling the bulbs using your phone, you can dim them up and down using standard on/off switches. Just flip the switch off and then back to start fading the light up or down. When it's at a level you want, flip the switch off and then back on a second time to lock it in.
The app does a good job of walking you through the setup process. Just plug the hub into your router and into power, and the app should detect it. From there, you'll enter its HomeKit pairing code into the app. Then, just screw in your bulbs and tap on the top of the hub to add them to your setup.
The Nanoleaf Ivy bulbs put out about 700 lumens from a very low power draw of just 7.5 watts, good for about 94 lumens per watt. That's more efficient than any other smart bulb we've tested to date. And, as you can see, the bulb's unique design doesn't stop it from putting out an even, omnidirectional quality of light.
