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.
