The photometric measurement of the flashing light is essential in the evaluation of various flashing-light sources used in many applications. The effective intensity is used to specify the intensity of flashing lights, and it is the primary quantity of them. In this paper, the measurement principle and instruments for the effective intensity of flashing lights are mainly described, the related problems and their corresponding solutions are presented, some key techniques for instrument developments including synchronism control, standard detector, high-speed data acquisition circuit are briefly discussed, and these key techniques are successfully applied to the development of the homemade flashing light effective intensity tester. The experimental results showed that these key techniques are very useful for the instrument research and development of the effective intensity measurement.
