The LED lamp market is projected to grow by more than twelve-fold over the next decade, from $2 billion in the beginning of 2014 to $25 billion in 2023, a compound annual growth rate (CAGR) of 25%. As of 2016, LEDs use only about 10% of the energy an incandescent lamp requires.
According to one study, the initial cost of a typical LED traffic signal ball was around $70 compared to an incandescent signal at $20. When energy use and maintenance costs were added, the total lifetime operating costs of LED lights were approximately one-third that of incandescent signals.
