During the last decade, lighting has become energy efficient across most sectors in the United States. However, the residential sector shows the least efficiency in lighting because of the use of incandescent lighting. To understand the reason for the slow growth in the adoption of energy-efficient residential lighting, this study identified factors influencing the purchase of energy-efficient lighting products, the willingness to pay more for energy-efficient lighting, and support for policies that ban the use of inefficient lighting in the home. Through systematic random sampling, a mail survey was conducted with homeowners in the Midwest region of the United States. The final sample consisted of 307 respondents. Factor analyses and three multiple regression analyses were conducted. The results revealed that residents' adoption of energy-efficient lighting was predicted by their attitude toward the environment and toward energy-efficient lighting, habitual energy-saving behavior, and their perception of the quality of energy-efficient lighting products.
