You may have noticed that many electrical items and light bulbs only have energy efficiency class E or F. The reason is the following: In September 2021, light bulbs and other illuminants received new energy labels from the EU.
Technical progress has steadily increased in recent years and led to significant improvements in energy efficiency. As a result, many products were in the top efficiency classes from A - A++. The differences in energy efficiency were hardly noticeable and the low classes almost completely disappeared from the market. Therefore, the EU decided to revise the energy label. The new class divisions are now much finer and the products are again more widely distributed. This relabeling often led to an energy drop from class A+ to F, for example.
The advantage is clear on the consumer side. From now on, they can better recognize energy-efficient devices with the new label.
As an example, an LED light bulb with a brightness of 550 lumens today consumes about 7 watts of energy. With about 78 lumens per watt, it was assigned class A+ with the old energy label. However, to achieve this class with the new energy label, a full 210 lumens per watt consumed are required.
In reality, however, only very few manufacturers currently achieve this.
The requirements for us manufacturers were thus significantly increased and we thus received an incentive to further improve our products and make them even more energy-efficient.
