Energy labels

Energy Efficiency

In the world of LED lighting, energy efficiency is critical. It affects not only our energy consumption, but also the choices we make when buying new bulbs. As of Jan. 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 look at the details of this new label, the calculation method and the transition from the old label to the new system.

The New Energy Efficiency Label

The new energy efficiency label for LED lighting provides consumers with a clear overview of a lamp's energy efficiency from A to G with A being the most economical label and G being the least economical label. Unlike the old label, which worked 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 bulb.

Calculation method

To determine the energy efficiency label, the ratio of light output (expressed in lumens) to 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. Energy consumption should be expressed in kilowatt-hours (kWh) and 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
A 210>
B  185 - 210
C 160 - 185
D 135 - 160
E 110 - 135
F 85 - 110
G <85


Saving energy

By switching to more energy-efficient lighting products, you can save about €30 per year. With more efficient lighting products, Europe could also save up to 34 TWh of electricity per year by 2030 and avoid the emission of about 7 million tons of CO2 per year. (source:European commission)

Here are some tips for saving energy with LED lighting:

  1. Replace old bulbs: Replace traditional incandescent and halogen bulbs with energy-efficient LED bulbs. LED bulbs use much less energy and have a longer lifespan.
  2. Choose the right light output: Choose LED lamps with the right light output (indicated in lumens) for the desired application. This will prevent overexposure and unnecessary energy consumption.
  3. Use dimmers: Use dimmable LED lamps in rooms where you want to be able to adjust the brightness. This allows you to reduce energy consumption and create atmosphere.
  4. Use motion sensors: Install motion sensors in areas that are not constantly occupied, such as hallways, stairwells and storage areas. This way, lights are turned on only when needed, saving energy.
  5. Switch to smart lighting systems: Take advantage of smart lighting systems that allow you to control and schedule lighting remotely. This allows you to optimize energy use and adjust it according to your needs.
  6. Make use of natural light: Take full advantage of natural daylight by keeping curtains and blinds open. This way you can reduce the use of artificial lighting.
  7. Maintain your lights: Keep your LED lights clean and free of dust, as dirt can reduce light output. Regular maintenance ensures optimal performance and longer life.
  8. Turn off lights when not needed: Teach yourself and others in the home 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 bulbs from reliable brands. While they may be slightly more expensive, they will last longer and offer more efficient lighting.

Differences from the Old Energy Efficiency Label

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

Requirements for Companies in the Netherlands

For companies offering LED lighting in the Netherlands, it is important to comply with the Energy Labeling Regulation. This means that all LED lamps placed on the market after March 1, 2023, must have the new energy efficiency label. The label must be clearly visible to consumers and contain appropriate information, such as lumen-per-watt rating, power consumption and energy efficiency class.


The new energy efficiency label is an important step forward in the world of LED lighting. It provides consumers with a better understanding of 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, 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, high-quality light.

For companies in the Netherlands, it is important to be aware of the energy labeling regulation and 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 sustainable lighting industry.

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