Shinggan na power circuit hpe matut da ai shaloi, transformer pru ai n-gun gaw, wan law law (sh) wan hku law ai voltage hpe shapraw ya lu ai. Ndai n-gun kaba ai wan n-gun hpe neon hka htung a lahkawng maga na electrode ni hta bang dat ai shaloi, hka htung kata na charged particle ni gaw n-gun kaba ai-wan n-gun field hta lawan ai hku rawt jat wa nna, electrode ni hpang de nbungli hte lung wa ai majaw, electron law law pru wa ai. Ndai excited electron ni gaw, n-gun kaba ai-wan n-gun field hta lawan ai hku rawt jat wa nna, hka htung kata na gas atom ni hte hkrat sum mat ai.
Ndai electron ni a n-gun gaw, lawt lu ai wan atom ni hte gap hkat ai shaloi, wan atom ni gaw, kaja ai ion hte electron ni de ion byin mat wa ai; ndai gaw gas ionization ngu ai mabyin masa rai nga ai. Charged particles hte gas atoms ni a lapran hkrat sum ai kaw na law htum n-gun gaw photon ni a hkrang hku pru wa nna, dai hku nna tube hpe htoi tu shangun ai neon nhtoi a lam yawng hpe ngut kre hkra galaw lu ai.
