# Commission Implementing Decision (EU) 2016/160 of 5 February 2016 on the approval of the Toyota Motor Europe efficient exterior lighting using light emitting diodes as an innovative technology for reducing CO2 emissions from passenger cars pursuant to Regulation (EC) No 443/2009 of the European Parliament and of the Council (Text with EEA relevance), Division 4.1: Calculation of the power savings

Extent: E+W+S+N.I.

For each of the five measurements the power which is used is to be calculated by multiplying the installed voltage with the measured current. When a stepper motor or electronic controller is used for the supply of the electricity to the LED lamps, then the electric load of this component part is to be excluded from the measurement. This will result in five values. Each value must be expressed in four decimals. Then the mean value of the used power will be calculated, which is the sum of the five values for the power divided by five.
The resulting power savings are to be calculated with the following formula:
Formula (1):
ΔP = Pbaseline – Peco-innovation
Where:
ΔP Power savings [W];
Pbaseline Power of the baseline, specified in Table 1 [W];
Peco-innovation Mean value of the used power of the eco-innovation [W].
