After inventing the first visible light emitting diode, General Electric has harnessed that power to develop a light bulb to be available later this year or early 2011 and expected to provide a 77 percent energy savings. The GE Energy Smart® LED bulb should also produce nearly the same light output as a 40-watt incandescent bulb, while lasting more than 25 times longer. The bulb is expected to last for 17 years on an average 4-hour per day usage. Imagine installing a light bulb in your house, paying pennies on the dollar for electricity usage and not having to replace the bulb for almost two decades! The bulb lights up to 450 lumens, more than enough to provide the same light as a 40-watt incandescent bulb. Retailers set the final price, but the bulb is expected to cost $40 – $50 at least initially. To learn more about the bulb and compare with other, conventional lighting, click here.
