Lighting is a key design element that contributes to the identity, comfort and visual quality of a retail store. But there are very few studies reflecting the effect of lighting on humans in the retailing contexts. Most of these studies were done in the laboratory contexts neglecting the natural settings. This study specifically aims to fill this gap by understanding the role of in-store lighting in the formation of store satisfaction. Data for the study was collected from a groceries retailer in India. The factor and regression analyses found that store lighting which enhances the image of the store contributes more to the formation of store satisfaction than the store lighting which enhances appeal of the store.
