There Efficiency of Yet Another Kickstarter-funded LED Bulb

When it comes to energy-efficiency the NanoLight's 12-watt LED bulb doesn't waste its power dazzling with illuminating design aesthetic. Rather, the origami-esque folded circuit board hits the switch declaring it's product, "the World’s Most Efficient Light Bulb.” The Kickstarter-funded heat sink-free bulb claims to produce over 1600 lumens while consuming only 12 watts, and to last 25 to 30 years based on three-hour a day usage.
