A color-changing LED can set the mood

A few months back I reviewed the Philips Hue Personal Wireless Lighting system and found it to be quite cool, but expensive. The Hue starter system includes three bulbs and costs $200. The bulbs are controlled wirelessly through a mobile app to change color, brightness and turn them on and off. If you liked the idea of the Hue, but would like to start at a price less than $200, you should look at the Lumen Bluetooth Smartbulb. The Lumen (lumenbulb.net, $49 from Amazon) is a single 400-lumen LED bulb that talks to your smartphone or tablet via Bluetooth.
