This past May, the price of LED light bulbs declined globally by 1 percent. LEDInside, a research division of TrendForce, found that the most obvious price reduction was in Taiwan, but the U.S. also experienced a decrease as well.
The cost of LED light bulbs is higher than older incandescent bulbs, but is much more efficient, and offers a longer life. The increasing popularity of energy-saving lighting, and the demand for LED technology, signals a huge growth in the market and a lower cost of LED.
"As well as the dropping prices, the low energy-consumption of the [LED] bulbs will help those purchasing now to see lower energy bills almost immediately."
