Light often affects us subconsciously. Especially in supermarkets, flower shops, jewellers or restaurants, professional literally put their goods and services in the best possible light. You can try out these tricks very easily within your own four walls with the help of special luminaires. Ice-blue lamps emit a cool blue light thanks to their high colour temperature of 20,000 Kelvin. Glass, silver or porcelain shines particularly brightly as a result – ideal for shelving units and display cabinets.
