A crucial role in retail lighting is played by the lighting design project, which helps to avoid areas of insufficient illumination on the one hand, and over-lighting or excessively intense light on the other: in both cases, the customer develops a desire to leave the store prematurely, without making a purchase.
A modern trend in retail lighting is adjustable color temperature, which changes depending on the time of day or the tasks set by the retailer. Different scenarios often operate for various zones of the store.
In the illumination of supermarkets and large stores, both general-purpose light fixtures and accent light fixtures with neutral white light and a high color rendering index are used. This helps the customer to see the product clearly and, at the same time, encourages them to move quickly through the sales floor from one product group to another.
The light fixtures with specially developed spectra are also often used to solve specific tasks (for example, light fixtures for illuminating fresh baked goods with a characteristic warm color, etc.).
