Lighting the groceries

Lighting groceries in the right way is a very important task. It is not only about a commercial lighting design, but there are also many functional aspects.

Make the groceries stand out

There are a couple of different filters that are central when it comes to meat and fish.Deli departments and fridges with fresh, high quality meat products are perfectly matched with light that has most of the radiation in the warmer, red spectrum. This can be achieved using different techniques like metal halide with meat filters, STH, LED-modules or metal halide light sources that are specialised for this application.


The result of the preferred solution is a vibrant red and fresh looking deli department. When planning the lighting solution for meat it is important to make sure that the light sources are not placed too close to the produce, to avoid the heat radiation destroying the produce.

Salmon and shrimps are typical foods that, if combined with a warmer light source, will attract customers by enhancing the red and pinkish colours of the seafood. Cooler light is used to enhance the blue colours of the food and in the ice. The difference in colour temperature does not “kill” each other since warm and cool colour contrasts enhance each other. The fish counter is an area where you usually experience a cool feeling as the fresh goods have to be kept cool, so it won’t be destroyed. To enhance this experience it’s common to use light sources with a Kelvin degree of above 4000K.

Fruits and vegetables are products that also feel comfortable in warmer colour temperature. This can be achieved by using a light source with 2700K, coloured reflectors such as gold or yellowish coloured reflectors or a STH light source

The warm colours in bread and cheese are enhanced by the low degrees of Kelvin(<2700K), due to the high amount of warm wavelengths in the spectral distribution. This makes products with warm hues look even warmer and more attractive.
