Human-Centric Lighting at a German Supermarket Boosts Sales by 28%

The trial of the technology at an Edeka store in Lower Saxony saw total sales increase by 12 per cent compared to a nearby reference store, with confectionary sales rising by 28 per cent, fruit and vegetables by 26 per cent, wines and spirits by 23 per cent and pre-packaged meat by 23 per cent. The scientific study, conducted over 10 months, also saw customer dwell times boosted by 21 per cent and employee absence tumble by 35 per cent. In the morning the lighting is a neutral-white colour temperature of 4000K with a horizontal illuminance of 700 lux. At midday and in the afternoon the colour temperature rises to a cool white 5000K and the illuminance to 1,000 lux horizontally. Towards evening the horizontal illuminance drops to 600 lux and the colour temperature falls to a warm 3000K. http://luxreview.com/article/2018/11/human-centric-lighting-boost-supermarket-sales-by-28-
