Structural equation modelling in lighting research: An application to residential acceptance of new fluorescent lighting

The present study serves as a vehicle to introduce structural equation models into the field of lighting research. Structural equation models are representations of relationships among variables. This study examined relationships among some of the beliefs people hold about fluorescent lighting in general and their decision to use new compact fluorescent lighting in their homes. The goal of the study was to determine which beliefs best predict usage. A questionnaire was designed to survey beliefs, attitudes, and behaviours related to fluorescent lighting. Questionnaires were completed by thousands of individuals attending the New York State Fair. To determine which beliefs best predict attitude toward fluorescent lighting, and usage of compact fluorescent lighting in the home, the relationships among all the variables were analysed using LISREL, a structural equation modelling technique. This powerful method provides a means to investigate unobservable constructs such as beliefs and attitudes, as well as other subjective variables. Our analysis showed that behaviours, such as using compact fluorescent lights at home, could be predicted successfully from the beliefs and attitude people hold about conventional fluorescent lighting. These findings have implications for designing educational and informational programs intended to increase use of compact fluorescent lighting in the residential sector.
