Point detail

For any cornering lamp except those equipped with filament lamp(s), the luminous intensities, measured after one minute and after 10 minutes of operation, shall comply with the minimum and maximum requirements. The luminous intensity distributions after one and after 10 minutes of operation shall be calculated from the luminous intensity distribution measured after photometric stability has occurred by applying at each test point the ratio of luminous intensities measured at 45-L 2.5-D for a left-side lamp (the L angle should be substituted for the R angle for a right-side lamp):

For any cornering lamp except those equipped with filament lamp(s), the luminous intensities, measured after one minute and after 30 minutes of operation, shall comply with the minimum and maximum requirements. The luminous intensity distribution after one minute of operation can be calculated from the luminous intensity distribution after 30 minutes of operation by applying at each test point the ratio of luminous intensities measured at 45-L 2.5- D after one minute and after 30 minutes of operation for a left-side lamp (the L angle should be substituted for the R angle for a right-side lamp).
