  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.
