"Mocheso o hlahisoang ke li-LED o hatelloa ke ts'ebetso e kopaneng ea hona joale ea ho fokotsa lintlha," ho latela Rohm. "Phallo ea motlakase e fetoloang hajoale e lekanyetsa mocheso o hlahisoang ke li-LED, e eketsa nako ea tsona ea bophelo, e leng se etsang hore mokhanni oa LED a tšoanelehe bakeng sa tšoeu le li-LED tse khubelu le tse tšehla."
