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. Gold light lamps with a low colour temperature of only 2,000 Kelvin look as homely warm as candlelight. A standard warm white LED lamp has a light colour of 2,700 to 3,000 Kelvin. The difference is obvious and creates a completely different atmosphere in the room. Restaurants, for example, use it to create a cosy and festive ambience.
