As food producers turn to controlled environment agriculture (CEA) to feed growing populations while facing decreasing arable land acreage, climate change, and other challenges, it is crucial to understand externalities associated with controlled environment agriculture. The use of efficient and versatile light-emitting diode (LED) supplemental lighting systems for increased profits for those producers presents a unique set of externalities including light pollution. Using an online survey and Tobit model, the authors find that after showing individuals images of light pollution from supplemental LED lighting sources, most survey participants want more regulation of those sources. The most popular candidate for regulation of LED lighting systems among participants in this study is state government. There are several significant factors influencing survey respondents’ post-treatment preference outcomes for different levels of regulation and regulators including demographic characteristics as well as initial attitudes towards LED lighting systems before treatment.
