Coop Logistics

Installation of light fittings at Coop supermarket in Västerås, central Sweden, was carried out by Assemblin while the customer’s storage areas were in full operation.

This reduced the maintenance costs for lighting in the cold storage areas, since fewer strip lights with a longer life means fewer replacements. It is important to note that the lights are never regulated down to less than 10 percent. This is partly due to safety: the customer wants the storage areas to have some remaining guiding light also in areas that are not currently in use.

Light regulation in a cold storage room (+2°C) places great demands on the technology. Light regulation in refrigerated spaces used to be regarded as technically and economically unfeasible. One important consideration in a cold room is that excess heat from the lights themselves has to be cooled off.

A more efficient light fitting and light source saves roughly 20 percent energy. The lights have to be narrow-beam to cope with the cold surroundings. The actual light regulation contributes a further 50 percent energy saving.
