A new study from Pike Research forecasts that LEDs will account for almost half of a $4.4 billion market for lamps in the commercial, industrial and outdoor stationary sectors by 2020. Almost 18 percent of global electricity use goes toward lighting, and lighting in the U.S. consumes a fifth of the amount at an annual cost of more than $40 billion. LEDs present an opportunity to cut expenses and reduce electricity use since they consume less energy and last far longer when producing the same amount of light as traditional bulbs.
