In this work we have developed a lightning simulator. Reproducing the light of lightning, we adopted seven waveforms that contains two light waveforms and five current waveforms of lightning. Furthermore, the lightning simulator can calibrate the color of the simulated light output based on a correlated color temperature (CCT). The CCT of the simulated light can range over from $4269$ K to $15042$ K. It is considered that the lightning simulator is useful for the test light source of the optical/image sensor of the lightning observation. Also for science education (e.g. physics education and/or earth science education etc.), the lightning simulator is available. In particular, the temporal change can be slowly seen by expanding the time scale from microsecond to second.<br/>v1:15 pages, 11 figures, 3 tables, 1 algorism. v2:corrected English expressions in a few sentences<br/>
