The Future of LED Lighting?
In August 2012, McKinsey & Company published Lighting the Way: Perspectives on the Global Lighting Market, a comprehensive analysis of current and future trends in the lighting industry. Below are excerpts from the report.
LED prices have eroded more aggressively, pulling forward the payback time of LED lighting. The inflection point for LED retrofit bulbs in the residential segment, for example, is now likely to be around 2015.
The value-based LED market share for 2011 is estimated at around 8 percent in North America. This is expected to grow to around 45 percent in 2016 and around 70 percent by 2020. Faster LED price erosion is supporting the accelerated uptake of LED.
The price of LEDs is tumbling even faster than anticipated, helping to further drive technology transition. The green revolution in lighting is also continuing apace, with other energy-efficient lighting technologies being acknowledged as a bridge towards full LED penetration.
The price premium on LED lighting products still remains high, and the initial purchase price represents a significant barrier to decision makers when considering an initial investment in general lighting applications. However, faster LED price erosion is pulling forward the payback time of LED lighting. Our analysis shows, for example, that faster price erosion in residential LED bulbs and office LED tubes is bringing forward the payback time in 2016 by one to two years. It is expected to be less than two years by then in the residential segment.
The largest application market in general lighting, residential, represented almost 40 percent of the total general lighting market in 2011. The LED market share in residential was estimated at around 7 percent in 2011 and is expected to be almost 50 percent in 2016, rising to more than 70 percent in 2020.
