Ha potoloho ea matla a kantle e hokahantsoe, tlhahiso ea transformer e hlahisa matla a phahameng a likete tse 'maloa kapa esita le mashome a likete a li-volts. Ha motlakase ona o phahameng o sebelisoa ho li-electrode lipheletsong ka bobeli tsa tšupu ea neon, likaroloana tse chajitsoeng ka har'a tšhupu li potlakisoa sebakeng sa motlakase o phahameng-ebe li fofela ho li-electrode, 'me li hlahisa lielektrone tse ngata. Li-electrone tsena tse thabileng li potlakisoa sebakeng sa motlakase o phahameng-'me li thulana le liathomo tsa khase ka har'a tšupu.
Ha matla a lielektrone tsena tse thulanang le liathomo tse sa lefelloeng tsa khase li le khōlō ka ho lekaneng, liathomo tsa khase li kenngoa ka li-ion le lielektrone tse ntle; sena ke ketsahalo ea ionization ea khase. Matla a feteletseng a tsoang ho likhohlano pakeng tsa likaroloana tse qosoang le liathomo tsa khase a ntšoa ka mokhoa oa photons, kahoo ho phethela ts'ebetso eohle ea leseli la neon le khantšang tube.
