Webphotometer heads are matched to the (λ) function with CIE values [5] ranging from 1.7 % to 1.9 %. Since anticollision lights have two colours (white and red) with spectral power distributions different from those of the CIE Illuminant A, a spectral mismatch correction factor was evaluated for each colour. Four current integrator units have ... Webphotometer heads vary with different application conditions or measurement conditions.
