Hue White + Hue Bridge
I have an iPhone, so the bulbs can be used directly via Bluetooth with HomeKit or the Hue app, or with the Hue Bridge to control them with the Siri voice assistant.
Light intensity can be controlled independently for each lamp, by room or by zone.
The Hue Bridge is useful when you're using several Hue devices, as it lets you control your lighting (intensity, colour), and can be triggered remotely, depending on where you are when you get home, or according to the time of day, or the amount of sunlight, and third-party applications are also available.
A great kit for a small house or flat, and very upgradeable.
