LED replacement lamps in the general service submarket became available to consumers between 2007 and 2009 at a typical cost over $50 per lamp, and struggled to match the efficiency of incumbent CFLs. The high first cost and limited energy savings over CFLs has limited the uptake of LED lighting in general service applications, but significant improvements have been made in recent years. As a result, the lighting market model predicts that LEDs will be the dominant technology in general service applications by 2020, having an overall market share, shown in Table 3.2, of 55% across the three indoor sectors.
