Product information regarding energy efficiency
Label for energy efficiency
Obligations for e-commerce
As a seller of light sources, since September 1, 2021, we are obliged to report the energy class of the light source. The class is shown in a gradation from A to G, where A corresponds to the best efficiency. Through the Energy Labeling, it should make it easier for the user to choose light sources based on their energy efficiency. The energy class is shown at this location through the product's energy label. The energy class and efficiency are also reported in the light source's data sheet, which can be downloaded higher up on this product page.
Energy efficiency classes and calculation method
The energy efficiency class for light sources shall be determined according to Table 1, based on light output based on the power from the mains ηTM, which is calculated by dividing the declared usable luminous flux Φuse (expressed in lm) by declared power consumption in position Pon (expressed in W) and multiplying by applicable FTM in Table 2, i.e. ηTM = (/use / Pon) x FTM (lm / W).
| Energy efficiency class | Light exchange based on the power from the mains ηTM (lm / W) |
|---|---|
| A | 210 ≤ ηtm |
| B | 185 ≤ ηtm <210 |
| C | 160 ≤ ηtm <185 |
| D | 135 ≤ ηtm <160 |
| E | 110 ≤ ηtm <135 |
| F | 85 ≤ ηtm <110 |
| G | ηtm <85 |
