Philips Hue Light Bulbs

At $200 for a package, Philips Hue Light Bulbs might not be the most affordable gadget on this list, but if you can afford it, the Hue is extremely useful. Like any old light bulb, the Hue can screw in anywhere, but that’s where the regularity begins and ends. Hue can be programmed through an app to flash when you get an urgent email, Facebook notification or get mentioned in a tweet. But that's not all the Philips Hue can assist you with. When you walk in the door, Hue can sense your phone and automatically turn the light on. It also changes colors at will to create scenes like "energize" or "concentrate" and lasts up to 5 years before you need to change it. In all, Hue is pretty useful, convenient and fun -- it’s just not the most thrift-conscious buy on the list.
