The energy label of a light bulb

Energy labels provide information about the energy efficiency of lamps, but also of other products such as electrical devices. The higher the energy efficiency class, the more the product consumes energy and thus electricity. It is therefore advisable to look at the energy label before buying.

The most important things at a glance:


  • Energy labels are available for many electrical products: Lamps, cars, refrigerators, etc.
  • New energy label 2021: from September, scale from A to G for lamps, LED modules and lights.
  • QR code on the energy label leads to a product database with information

 

 

Update: new energy label 2021

According to the new Energy Labelling Regulation (EU) 2019/2015 (ELR for short), lamps, LED modules and lights where the light source cannot be removed without destroying it will have to bear a new energy efficiency label from September 2021. This will show a scale from A to G, which will make it easier for you to choose an efficient light source. In addition, the new energy label will be supplemented by a QR code. This provides you with important product information, which should also help you in your choice. The aim of the new regulation is thus to create a particularly consumer-friendly energy label.



Note on the transition period

Until the end of February 2023, you will find both the old and the new energy label in the shops. The relabeling will take place during these 18 months. From March 2023, the new energy label will be mandatory for all lamps, luminaires and LED modules.

 

 

How are the new energy efficiency classes calculated?

With the new energy label, the calculation of energy efficiency classes has also been redefined. A direct assignment of products based on their old label is not possible. Therefore, the new energy efficiency class must be calculated as follows:

 

The class is determined by calculating the total luminous efficacy ηTM from the specified useful luminous flux Φuse, the specified power consumption Pon and multiplying it by the total Mains factor FTM.

 



light source Total Mains Factor
Unfocused light (NDLS), directly connected to mains voltage (MLS) 1,000
Unfocused light (NDLS), not connected to mains voltage (NMLS) 0,926
Bundled light (DLS), directly connected to mains voltage (MLS) 1,176
Bundled light (DLS), not directly connected to mains voltage (NMLS) 1,089

 

Finally, the above calculation results in the following energy efficiency:

 

energy efficiency total luminous efficacy in lm/w
A 210
B 185 to 210
C 160 to 185
D 135 to 160
E 110 to 135
F 85 to 110
G to 85

 

 

Comparison: new and old energy label

 

New energy label as of 01.09.2021

must be indicated on all light sources with a luminous flux between 60 and 82,000 lumens and OLED (lamps, LED modules and fixtures where the light source cannot be removed without destroying it).

Information on the label:

  • Name / Trademark
  • Model
  • Energy label scale A to G
  • Energy consumption for 1,000 hours of use
  • Energy efficiency class of the product
  • QR code to EPREL (product database of the European Product Registry for Energy Labelling)

 

 

 

Old energy label until 31.08.2021

must be indicated on all lamps, fixtures and LED modules with a luminous flux of more than 30 lumens.

Information on the label:

  • Name / Trademark
  • Model

the old energy label

 

 

The previous energy label

Since 1 September 2013, there has been a revised version of the EU energy label for lamps published in 1998. As before, the label shows the manufacturer and the product code as well as the energy efficiency class of the lamp.

Added are the two classes, A+ and A++, and the indication of the power consumption in kilowatt hours for 1,000 hours of use. The classes E to G have been abolished. In addition, not only lamps with unconcentrated light are now taken into account, but also lamps with concentrated light such as spotlights.

LEDs always have at least energy efficiency class A. The same applies to fluorescent tubes and energy-saving lamps. When you buy an LED light of class A++, you save up to 90 % of electricity compared to a luminaire of class D.

 

 

The old energy efficiency classes

Lamps and luminaires have an energy label showing their energy efficiency on a scale from A++ (most efficient) to G (least efficient). Without an energy label or if the information provided is incorrect, the manufacturer may face sanctions.

 

energy efficiency class lamp type
A++ to A LEDs
A+ High Pressure Sodium lamps
A to B

Compact fluorescent lamps

B

Halogen lamps with infrared coating

C

Halogen lamps with xenon gas filling 230 V

C

Conventional halogen lamps at 12 - 24 V

D to F

Conventional halogen lamps at 230 V

E to G

light bulbs

 

Since 2012, due to the European Union regulation, there are minimum requirements that lamps with clear glass and unconcentrated light must have class C. Lamps with matt glass must have at least class A. Incandescent bulbs may therefore no longer be produced since then because of their poor energy efficiency. High-voltage halogen bulbs are also slowly disappearing from the European market because of their enormous power consumption.

 

 

Further measures

Since 1 September 2018, the next and final step of Regulation (EC) No 244/2009 has been in force. Main voltage halogen lamps no longer comply with EU eco-design guidelines and can therefore no longer be sold on the market. The remaining stock will continue to be sold and used. Excluded from this are the rod-shaped R7s halogen lamps and G-halogen pin-base lamps.

 

As early as the end of 2019, luminaires no longer have to bear an energy label. However, the label does not have to be removed from the packaging of products that are already on the market.
