LIFX Kickstarter LED Bulb has to be one of the most impressive kickstarter proposals I have seen in years.
The $69 donation landed backers a bulb from the first production (ETA March 2013). The 1.3M only took a few of days to reach.
Interested in controlling lights though your phone now? Philips launched the Philips Hue System at Apple stores and online. The package with 3 bulbs and control hub will only set you back $199.
