Energy conservation through the adoption of new, energy-efficient technologies will succeed only to the extent that the new technologies are not themselves perceived as risk sources. Previous research has found that beliefs about the health effects of fluorescent lighting predict compact fluorescent lamp use in homes. This paper describes the development and validation of a questionnaire to assess beliefs about the effects of common types of interior lighting on human health, work performance, mood, and social behavior. Principal components analysis of the 32-item Lighting Beliefs Questionnaire revealed 6 interpretable components: Lighting Importance, Brightness, Major Health Effects: Fluorescent Lighting, Minor Health Effects: Fluorescent Lighting, Social Setting, and Daylighting. The questionnaire may be used to explore responses to interior lighting and to discover what beliefs are held by end users. This information will assist in allaying unwarranted fears and concerns about new lighting technologies.

Among those concerned with practical matters of office design, demonstrations that the work environment affects employees' well-being and work behaviors are thought to be important to support client decision making. Veitch, Newsham, Boyce, and Jones developed a conceptual model in which lighting appraisal and visual capabilities predicted aesthetic judgments, mood, and performance. This article extends that model to include measures of work engagement, using experimental data originally reported by Newsham, Veitch, Arsenault, and Duval. Structural equation modeling showed strong fit to a model in which lighting appraisals indirectly influenced work engagement through aesthetic judgments and mood. This evidence that providing a satisfactory work environment can contribute to employee effectiveness merits further study by environmental and organizational psychologists.
