Taim ol i konektim pawa seket bilong ausait, autput bilong transfoma i save kamapim bikpela voltej bilong sampela tausen o ten tausen volt. Taim ol i putim dispela bikpela voltej long ol 'electrodes' long tupela arere bilong 'neon tube', ol 'charged particles' insait long 'tube' i save go hariap insait long 'high-voltage electric field na flai i go long ol 'electrodes', na kamapim planti 'electrons'. Ol dispela 'excited electrons' i save go hariap insait long 'high-voltage electric field na ol i save bam wantaim ol 'gas atoms' insait long 'tube'.
Taim strong bilong ol dispela 'electrons' i bam wantaim ol 'free gas atoms' i bikpela inap, ol 'gas atoms' i save kamap 'ionized' i go long ol 'positive ions' na 'electrons'; dispela em i samting bilong 'gas ionization'. Ekses eneji we i kamap long ol birua namel long ol 'charged particles' na ol 'gas atoms' i save kamap long kain bilong ol 'photons', na dispela i pinisim olgeta wok bilong 'neon light' we i lait long 'tube'.
