Residential lighting is used in sin

Residential lighting is used in single-family, multi-family, and mobile households, with the majority provided by lamps and/or luminaires in the general service and directional submarkets. Although residential lighting represents the largest number of installed lamps at approximately 5.8 billion in 2013, lamps in this sector are used for relatively few operating hours, averaging less than two hours per day and providing roughly 3,400 teralumen-hours of lighting service annually. Due to low lamp usage and limited lighting education, consumers in the residential sector place a higher value on the price of a lighting product rather than its annual costs. The residential sector as a whole is therefore less concerned with the efficacy and lifetime performance of lighting products. Due to the high efficacy and increasing penetration of LED products, as seen in Figure 3.5, the lighting market model predicts significant energy savings in the residential sector, estimating a 53% decrease in energy consumption compared to the no- LED scenario by 2030.
