A–G LED energy labels: how to read them and check EPREL
To read an LED light's energy label, start by identifying the model. Then check the A–G class, consumption per 1,000 hours and the QR code linking to EPREL. That sequence avoids comparing one variant with the documentation for a similar one.
The label helps assess efficiency using standardised information. To make a purchasing decision, you also need to check that the source provides the lighting you need and that the data matches the reference you will receive.
What the A–G energy scale means
The European Commission explains the rescaling applied to light sources since 1 September 2021. A is the most efficient category and G the least efficient on this scale.
The old classes with “+” signs belong to another system. An old letter and a current one are not equivalent. If you have an old box, find the model's current label before comparing; avoid translating A+ into a new letter by intuition.
The five details to find
| Detail | What it helps with | What to check |
|---|---|---|
| Supplier or brand | Identifying who declares the model | Consistency with the documentation |
| Model identifier | Distinguishing the exact reference | Full code and variant |
| A–G class | Comparing energy efficiency | That the same scale is used |
| kWh per 1,000 hours | Estimating consumption according to use | Stated unit and period |
| QR code | Accessing the model's entry | Official destination and matching details |
The light source energy labelling Regulation sets out these elements. Classification uses useful luminous flux, wattage and factors associated with the source type. Dividing two figures from commercial specifications is therefore not enough to certify a class letter.
Checking EPREL step by step
EPREL is the European Product Registry for Energy Labelling. According to the official information for suppliers, labels are generated from the data they register; the model page provides access to labels and product information sheets.
- Scan the QR code and check that it opens the eprel.ec.europa.eu domain.
- If you do not have a QR code, use the official light source search with the brand and identifier.
- Check the full model against the packaging, commercial specifications and chosen variant.
- Open the product information sheet and review the class and consumption.
- Save the link or document with the purchase reference.
A similar code warrants checking, especially when the wattage or variant differs. If the search returns no result, ask the seller for the exact link. Do not choose the closest-looking entry to fill in missing information.
Example: converting consumption into an annual estimate
Suppose a source's label states 8 kWh per 1,000 hours and it operates for four hours daily. Over a 365-day year, it would accumulate 1,460 hours: 8 × 1,460 ÷ 1,000 = 11.68 kWh. This is a calculated example unrelated to the products shown below.
With ten identical units on the same schedule, the estimate would be 116.8 kWh. Multiply by the applicable energy price to approximate that component of the cost. The full bill may include other charges, and the result changes if operating hours, dimming or additional consumption vary.
Before comparing alternatives, verify that they provide suitable lighting for the same use. Choosing solely by the lowest consumption can leave the area insufficiently lit. For spotlights, also check the distribution according to their beam angle.
Light source and containing product
The Commission distinguishes a light source from a containing product, such as certain light fittings. The ability to remove the source without permanently damaging it for verification is relevant; if that is not possible, the whole assembly is considered a light source for these purposes.
This classification does not mean that you can replace the LED at home. For maintenance, check the instructions and the guide to integrated LEDs or replaceable bulbs. When reading energy information, always ask which element the class letter applies to.
Two examples of commercial information to check
The following references help practise reading a product page. Verify each model in EPREL before using its class in a comparison. Images do not replace the energy label.
White and chrome LED reading wall light with USB-A 8 W 3000 K
The commercial specifications state class F for the light source. Request the documentation for the specific module and check it in EPREL; do not automatically attribute that letter to the whole wall light.
View product details and optionsWhat to do if you find a discrepancy
If the listing, box and document differ, keep a screenshot of each and request clarification, giving the complete model reference. Ask them to identify which label applies to the chosen unit. Leave the comparison pending until resolved, without assuming a typo or equivalence between variants.
Checklist before deciding
- I have the exact model identifier and variant.
- I am comparing labels on the same A–G scale.
- I have found the corresponding information sheet or requested it.
- I know whether the information covers the source or the whole assembly.
- I have estimated operating hours and checked the lighting required.
Frequently asked questions
Does class G mean it is not LED?
No. LED technology can appear in different classes. Check the model's label without inferring its technology from the letter.
Are the kWh per 1,000 hours my annual consumption?
No. You need to adjust them to the actual operating hours and the number of units used.
Does an EPREL entry certify every marketing claim?
No. It allows you to consult the model's registered information; other performance claims need their own supporting documentation.
Can I apply the class of any similar module to the wall light?
No. Request the details of the exact source and confirm which element the classification covers.
Does the energy class indicate how colours will look?
For that question, see IRC, CRI and colour rendering; these are different criteria.
