Energy labels

Energy Efficiency

In the world of LED lighting, energy efficiency is crucial. It not only affects our energy consumption but also the choices we make when purchasing new lamps. As of January 1, 2021, the European Union has introduced a new energy labeling regulation that requires an energy efficiency label for LED lighting. In this article, we will delve into the details of this new label, the calculation method, and the transition from the old label to the new system.

In Brief

• The label now uses a scale from A to G, where A has the highest light output combined with the most energy-efficient power and G has the lowest.
• Energy efficiency is calculated by relating the wattage of the lamp to the light output in lumens (lm).
• It is important to understand that the new lowest energy labels F and G do not mean that the lamp is not energy-efficient.
• LED lighting with an F or G classification can still be very energy-efficient and may consume much less wattage than LED lamps with, for example, an A to D label.
• LED lamps with labels A to D have a higher light output, but in many cases, this extra brightness may be unnecessary.
• LED lighting with an F or G label can be an excellent and energy-efficient choice, especially when the extra brightness of lamps with a higher label is not necessary.

The New Energy Efficiency Label

The new energy efficiency label for LED lighting provides consumers with a clear overview of the energy efficiency of a lamp from A to G, where A is the most efficient label and G is the least efficient label. Unlike the old label, which operated with classes from A++ to E, the new label uses a scale based on lumens per watt (lm/W). The higher the number of lumens per watt, the more efficient the lamp.

Calculation Method

To determine the energy efficiency label, the ratio between light output (expressed in lumens) and power consumption (expressed in watts) is calculated. This ratio is known as the lumen-per-watt value (lm/W). The energy efficiency label is determined based on the following guidelines.

Calculate the Energy Efficiency Index (EEI):

EEI = (Energy consumption / Luminous flux) * 1000. The energy consumption must be expressed in kilowatt-hours (kWh) and the luminous flux in lumens.

After this calculation, the energy labels are applied to LED lamps with the following Lumen/Watt efficiency:

Energy label	Lumen/Watt efficiency
	210>
	185 - 210
	160 - 185
	135 - 160
	110 - 135
	85 - 110
	<85

Save Energy

By switching to more energy-efficient lighting products, you can save approximately 30 euros per year. With more efficient lighting products, Europe can also save up to 34 TWh of electricity per year by 2030 and prevent the emission of about 7 million tons of CO2 annually.

Here are some tips to save energy with LED lighting:

1. Replace old bulbs: Replace traditional incandescent and halogen bulbs with energy-efficient LED bulbs. LED bulbs consume much less energy and have a longer lifespan.
2. Choose the right light output: Select LED bulbs with the appropriate light output (indicated in lumens) for the desired application. This prevents over-illumination and unnecessary energy consumption.
3. Use dimmers: Utilize dimmable LED bulbs in areas where you want to adjust the light intensity. This can help reduce energy consumption and create ambiance.
4. Use motion sensors: Install motion sensors in areas that are not constantly occupied, such as hallways, stairwells, and storage rooms. This way, the light is only turned on when needed, saving energy.
5. Switch to smart lighting systems: Use smart lighting systems that allow you to control and schedule lighting remotely. This can help optimize energy consumption and adapt to your needs.
6. Make use of natural light: Make optimal use of natural daylight by keeping curtains and blinds open. This can help reduce the use of artificial lighting.
7. Maintain your lighting: Keep your LED lamps clean and free from dust, as dirt can reduce light output. Regular maintenance ensures optimal performance and a longer lifespan.
8. Turn off lights when not needed: Teach yourself and others in the house to turn off lights in rooms that are not in use. A simple habit that can save a lot of energy.
9. Invest in quality: Choose high-quality LED lamps from reliable brands. Although they may be slightly more expensive, they last longer and provide more efficient lighting.

Differences with the Old Energy Efficiency Label

The old energy efficiency label used a different approach, where the energy class was primarily determined by the power consumption of the lamp. However, this did not provide a complete picture of the actual efficiency. The new label takes into account both light output and power consumption, resulting in a more accurate representation of efficiency.

Requirements for Businesses in the Netherlands

For businesses offering LED lighting in the Netherlands, it is important to comply with the energy labeling regulation. This means that all LED lamps launched on the market after March 1, 2023, must be equipped with the new energy efficiency label. The label must be clearly visible to consumers and contain the correct information, such as the lumen-per-watt value, power consumption, and energy efficiency class.

Conclusion

The new energy efficiency label is an important step forward in the world of LED lighting. It provides consumers with better insight into the energy efficiency of LED lamps and helps them make informed choices. By focusing on lumens per watt, lamps are encouraged to be more efficient, thus contributing to energy savings and sustainability.

With the new calculation method, consumers can quickly and easily compare the energy efficiency of LED lamps and make the right choice based on their specific needs. By aiming for lamps with a higher lumen-per-watt value, consumers can not only save energy but also enjoy brighter and higher quality light.

For businesses in the Netherlands, it is important to be aware of the energy labeling regulation and to ensure that their LED lamps meet the requirements. By correctly applying the new energy efficiency label, companies can inform consumers about the efficiency of their products and contribute to a more durable lighting industry.

In short, the new energy efficiency label for LED lighting provides transparency and clarity to consumers, encourages the development of energy-saving lamps, and contributes to a more durable future. It enables consumers to make informed choices when purchasing LED lighting and supports global efforts to promote energy efficiency.
