It should be bright enough to highlight the products and make them stand out but not so bright that it causes glare or strain on customers' eyes.
The supermarket lighting system should have different levels of light in different areas of the store, such as brighter lighting in the produce section and the bakery section to showcase the freshness of the products, and dimmer lighting in areas where customers may need more time to browse, like the wine or cheese section.
Lighting should also be positioned at the right angles and heights to avoid casting shadows on the products and to create a uniform lighting across the store. The lighting design should be energy-efficient and cost-effective, and it should be easily adjustable to accommodate changes in the store's layout or seasonal merchandise displays.
Overall, a well-executed lighting design can significantly add to the overall shopping experience, increase the time customers spend in the store, and enhance the perceived value of the products on display.
