With 10,000 stores in more than 30 countries, French supermarket chain Carrefour is a retail giant. At its Lille hypermarket, conventional fluorescent lights have been replaced with 2.5km of connected LED luminaires, complete with Philips indoor positioning technology.
The installation has halved the store’s energy consumption, having an immediate impact on Carrefour’s bottom line. Plus the unique qualities of the LED lighting have added color to food – particularly fresh produce and meats – making it more appealing to customers.
But Carrefour was looking for more than energy savings and stunning illumination from its investment. The company wanted to harness the power of connected lighting to strengthen its relationship with customers.
The installation included 800 linear LED luminaires, each incorporating Philips VLC technology, which can identify a customer’s in-store location to an accuracy of half a meter. Shoppers use Carrefour’s Promo C’ou app to access a store map, see promotions based on their shopping preferences and where they’re standing, and alert the supermarket to out-of-stock products.
