Philip Hue Color-Changing Light Bulbs

With Philip's new Hue light bulbs, the phrase "mood lighting" takes on a whole new meaning.

Hue lights are controlled via an iPhone and iPad app, which lets users turn them on and off remotely and even change their colors -- ranging from light yellow to bright blue -- to better fit the mood. A timer option is also included that gradually brightens the bulb's over time, transforming Hue into a less-jolting alternative to alarm clocks.

A three-bulb Hue start pack can be bought in Apple stores for $200. A single pack with one bulb is also available for $60.
