Below the results of this forecast are compared to six other forecast analyses to provide greater context. Included in the comparison set are the 2010 and 2012 iterations of the Energy Savings Forecast of Solid-State Lighting (SSL) in General Illumination Applications forecast analyses. Table 3.10 below lists these forecasts in decreasing order of projected LED market penetration in 2020. These forecasts vary in methodology, regions covered (i.e. U.S. market, global market), and units (i.e. sales by units, sales by value). Nonetheless, each presents a calculated impression of the importance of LEDs to the general lighting market in 2020.
