LED Hue Lights with iPhone and iPad App Control

New to the Apple Store as of Oct. 30, Philips' Hue LED lighting system can be controlled from iPhones and iPads. The starter pack includes three bulbs that screw into existing lamps and a small USB device that plugs into a Wi-Fi router, so that your phone or tablet can "talk" to the lights. What's really fun about this system is how you can program the lights in different color schemes based on a photo you like or use a "scientific" setting to help you concentrate. Starter pack: $199.

Light up the San Francisco Bay Bridge

The Bay Lights light sculpture honors the Bay Bridge's 75th anniversary and celebrates completion of the new East Span in 2013. Created with more than 25,000 energy-efficient, white LED lights, the sculpture is 1.8 miles wide and 500 feet high.
