Smartphone-controlled lighting. That is one of the true signs that the future is now, ladies and gentlemen. And Philips is leading the charge with its [slightly expensive] Hue light bulbs. So, how do these bad boys work? Let's cut to video:
It's pretty simple, actually. So, when you buy a Hue starter pack (... $200), you get three light bulbs, and a wireless bridge device. The bridge, acting as a, well, bridge, links the light bulbs to your existing wireless router. The bulbs communicate with the bridge using ZigBee Light Link (an open, low-power Wi-Fi standard), and the bridge then communicates with your wireless network, which then communicates with your Android phone or tablet.
