This study investigates the determinants of consumer purchasing intentions and the relationship between smart lamp product design and these intentions. It examines the impact of factors like social sustainability awareness, environmental sustainability awareness, perceived risk, health literacy, and product ease of use on the intention to purchase smart lights. Additionally, it explores the mediating role of altruism and the moderating effect of perceived usefulness in smart light purchasing decisions. Employing the Technology Acceptance Model (TAM) within an environmental context, the study employs a quantitative research method through surveys targeting Chinese consumers purchasing smart lights influenced by the observed variables. The findings reveal that consumers' purchase intentions for smart lights are significantly influenced by social sustainability awareness, while health literacy, perceived risk, and environmental sustainability awareness have limited impact on these intentions. Furthermore, product ease of use significantly affects consumers' intentions to buy smart lights. The mediation of perceived usefulness in the relationship between purchase intentions and social sustainability awareness is also significant. This study contributes to the literature by investigating multiple variables affecting consumer intentions towards smart lighting, offering valuable insights for practitioners in China's smart lighting market. However, its findings may not be generalized, and key elements like process and quality were not considered, suggesting future research opportunities for a broader scope and enhanced understanding.
