THAT WAS EASY ENOUGH:
Bright LED Bulbs Arrive At Last (Martin LaMonica, November 13, 2012, Technology Review)
Posted by Orrin Judd at November 13, 2012 3:57 PMOsram Sylvania this week is shipping an LED light bulb that gives off as much light as a 100-watt incandescent, a sign that lighting manufacturers have successfully tackled the technical challenge of making bright LED bulbs.The bulb gives off light in all directions, making it suitable for most applications, and consumes 20 watts of power. The expected retail price is just under $50. Osram Sylvania estimates that the bulb will save $220 over its life, assuming consumers pay the national average of 11 cents per kilowatt-hour.
