The standout is a new Wi-Fi-connected C by GE recessed ceiling fixture. Aside from letting you automate and dim the lights remotely, each fixture is color-tunable, allowing you to dial in to the specific color temperature of your choosing. Even more interesting: each light has its own microphone and speaker, letting it work as sort of a makeshift Amazon Echo in your ceiling. 

Which assistant you use is up to you -- GE says that you'll be able to pick between Alexa and Google Assistant. GE also tells me that it plans to make the lights compatible with Apple HomeKit, the set of iOS-based smart home protocols that let iPhone users control compatible smart devices using Siri commands -- though with HomeKit, you'll need to speak your commands into your phone's mic instead of talking to the light itself.
