In Short

The Hue series of lights from Philips are Wi-Fi connected devices that allow for control of lighting from a smartphone or tablet. The lightbulbs work in standard sockets and run over a Wi-Fi network and bridge. Users can set the color of the lamps to various settings depending on mood, holiday or whatever the occasion. Hue lights are available as a starter pack with four bulbs and a router, where add-ons are also available individually.

As of October 2015, Hue is offering a new bridge that's compatible with Apple's HomeKit and allows for, among other things, Siri control from iPhone or iPad.
