Grocery store lighting serves the dual purpose of increasing workspace functionality for store employees and creating a favourable shopping experience for customers. Different sections of the store require certain minimum thresholds of illumination. For example, light levels for displays and shelves should have higher visibility and allow customers to discern the details between competing product offerings. Meanwhile, out-of-customer-view areas like backroom storage do not share the same visibility requirements and can be more sparsely lit. A mix of best practices and workplace regulations should guide the overall development of the lighting design. Technical considerations of effective supermarket lighting design are best discussed with experienced professionals.
Colour Rendering Index (CRI) is the measurement of a light source’s ability to accurately portray different colours and is measured on a scale from 0 – 100 with 100 indicating the highest levels of colour accuracy. A high CRI enhances areas like the fresh produce section (as discussed above) where vibrant colours of foods on display can influence and entice the customer to buy more. Fluorescent lighting, as the traditional choice of supermarket use, addresses brightness requirements but does little to advertise the vibrancy of fresh products because this type of lighting typically has a low CRI in addition to suffering from the unwanted issue of flicker. All of LED World’s lighting fixtures have a CRI of 85 or higher.
