  "text": "For each efficient exterior LED light included in a combination, the measurement of the current shall be performed at a voltage of 13,2 V. LED module(s) operated by an electronic light source control gear, shall be measured as specified by the applicant.\nThe manufacturer may request that additional measurements of the current shall be performed at other voltages, where the necessity to do so can be demonstrated on the basis of verified documentation.\nIn any case the measurements (n) shall be performed for each voltage at least five times consecutively. The applied voltage and the measured current shall be recorded in four decimals.\nThe power consumption shall be determined by multiplying the voltage with the measured current. The average of the power consumption for each efficient exterior LED light () [W] shall be calculated as set out in Formula 1 with four decimals to be taken into account in the calculations. 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 is to be excluded from the measurement.\nFormula 1\nwhere,\nis the tested voltage of each LED vehicle light i\nis the measured current of each LED vehicle light i\nnis the number of measurements of the sample\njrefers to an individual measurement of power consumption\nIn case of low beam AFS, the power consumption () [W] shall be calculated as the average of the LED power consumption for each class k, weighted according to the NEDC time share per speed range, in accordance with Formula 2.\nFormula 2\nwhere,\nis the power consumption at the LED intensity for each class k as the average of n consecutive measurements.\nKis the number of classes associated with the low beam AFS.\nNEDC_shareis the NEDC time share per speed range in each class as defined in Table 2.\nTable 2\nNEDC time share per speed range\nSpeed range\nNEDC_share\n< 50 km/h\n0,6805\n50 – 100 km/h\n0,2881\n> 100 km/h\n0,0314\nWhen the low beam AFS does not fall within all four classes specified in Table 1, the NEDC_share of the missing classes shall be attributed to class C.",
