Carrefour "Light bulbs"

Playing off the typical retial "sale" environment, Carrefour placed flashy tags that appeared to be communicating huge savings on the purchase of compact fluorescent lamp (CFL) light bulbs. On closer inspection, customers were informed that with these efficient bulbs, the savings would be in energy. These tags were used during the Carrefour's Energy Saving Week.
