This paper presents a comparison of measurements of the waveforms of temporal light modulation (TLM) from 8 light sources performed by two different laboratories. The study focuses on the methodology of extracting relevant numerical differences between the measured waveforms. The methodology involves frequency matching, duration matching, selection of sampling interval, phase matching, normalization and results of the use of the methodology are presented. The results show that for some waveforms the comparison method can be used to practically explore equivalency of measurements.
