用能量守恒方程定性地验证了电流上升快的脉冲放电具有较高的电子温度。在充有汞蒸气和霓虹气体的管子的辉光放电中，正柱的发光颜色从霓虹灯发出的红色到方波脉冲放电发出的汞的蓝色不等。蓝光的亮度为数百尼特，红光的亮度最高为100NTS。在弧光放电中，方波脉冲很容易获得亮度较强的红光。另一方面，在高频下可以获得蓝光，但在该频率下放电变得不稳定。因此，电流波形改变方法对于弧光放电的发光颜色控制是有效的。
It is qualitatively verified by the energy conservation equation that high electron temperature is attained by the pulsed discharge with rapid current rise. In the glow discharge of the tube filled with mercury vapor and neon gas, luminous color of the positive column varies from the color close to red emitted by neon to blue of mercury by the square-wave pulsed discharge. Brightness of blue light is hundreds nits but that of red light is 100 nts at most. In the arc discharge, red light with strong brightness is easily obtained by square-wave pulses. On the other hand, blue light may be obtained at high frequency but the discharge becomes unstable at that frequency. Therefore, the current waveform alteration method is effective for luminous color control of the arc discharge.
