Lighting accounts for around 10 percent of Switzerland's electricity consumption. Since 2012, minimum requirements for the energy efficiency of light sources and control gears have been in force. In the course of the gradual tightening of these minimum requirements, almost all incandescent, halogen and integral compact fluorescent lamps have disappeared from the market today. An important further tightening will apply from 1 September 2023: from then on, the widely used T8 tubes (linear fluorescent lamps with a diameter of 26 mm) may no longer be placed on the market. However, existing inventory within Switzerland may still be sold during a transitional period until 31 August 2025.
Since 1 September 2021, light sources must be declared with the new energy label. In addition to the energy efficiency class, the label also shows the power consumption per 1000 operating hours. Initially, there are still hardly any products with an A-class rating. This «empty» class leaves room for the development of future efficient products. Existing inventory within Switzerland may still be sold with the old energy label during a transitional period until 31 December 2022.
