Ubuhlalu bengilazi bufika ngemibala ehlukahlukene, ngamunye unezici ezihlukile kanye nokusetshenziswa.
Ubuhlalu bengilazi bufika ngemibala ehlukahlukene, okufaka phakathi obala kanye nombala. Ubuhlalu bengilazi obusobala buveza ngokucacile ukwakheka kwabo kwangaphakathi, ngokuvamile kudala umuzwa wokuhlanzeka nokungafihli. Ubuhlalu bengilazi obunemibala bunikeza umbala ogqamile, njengokubomvu okugqamile, okuluhlaza okwesibhakabhaka okujulile nokuzolile, kanye nohlaza olusha nolwemvelo. Imibala yabo yakhiwe ngokuyinhloko ngokufaka izithasiselo ezihlukahlukene, njengama-oxides ensimbi, ngesikhathi senqubo yokwenza ingilazi. Isibonelo, i-cobalt oxide idala umbala oluhlaza okwesibhakabhaka, kuyilapho i-cuprous oxide idala obomvu. Emkhakheni wokuhlobisa, ubuhlalu bengilazi obunemibala bungasetshenziswa ukudala ubucwebe, izibani zokuhlobisa, nezinye izinto, zengeze intelezi eyingqayizivele. Ubuhlalu bengilazi obungafihli buvamise ukusetshenziswa kumathuluzi okukhanya, busizakala ngokudluliswa kokukhanya kwabo okuhle kakhulu. Ngaphezu kwalokho, umbala wobuhlalu bengilazi uyahlukahluka kuye ngezinto ezifana ne-engeli yokubuka nokuqina kokukhanya, okuholela kuma-hues ahlukene kanye nemiphumela evela kuma-engeli ahlukene, okuwenza athandeke kakhulu ukubuka nokusebenzisa.
1. Ubuhlalu bengilazi bufika ngemibala ehlukahlukene, futhi ubuhlalu bengilazi obusobala buwuhlobo oluyisisekelo. Azinazo izithasiselo ezithinta umbala, ngaleyo ndlela zigcine ukubonakala kwengilazi okungokwemvelo. Lo muzwa wokubonisa ngale ubaboleka izinhlelo zokusebenza ezihlukile kuzilungiselelo eziningi. Isibonelo, ekusetheni kokuhlolwa kwe-optical, ubuhlalu bengilazi obukhanyayo buvumela ukukhanya kudlule ngokushelela, okusiza ukubhekwa kwezinto ezifana nezindlela zokusakaza ukukhanya. Kweminye indalo yobuciko, ubuhlalu bengilazi obusobala bungaphinda busebenze njengento ehlanzekile, ebhangqwe nezinye izinto zokwakha umoya olula, we-ethereal.
2. Indlela yokwakheka kombala yobuhlalu bengilazi obunemibala iyathakazelisa. Ngokungeza ama-oxide ensimbi athile, umbala oyifunayo ungalawulwa ngokunembile. Igolide-isibonelo, ubuhlalu bengilazi obunombala, kungase kube umphumela wokwengezwa kwezingxenye zensimbi ezikhethekile. Lezi zingilazi zobuhlalu ezinemibala zisetshenziswa kakhulu embonini yokuhlobisa. Emigexoni emihle, namasongo, nezinye izesekeli, ubuhlalu bengilazi obunemibala budala indawo ebonakalayo, budonsela ukunaka. Zingahlanganiswa ukuze zenze izingcezu ezigqamile, ezimibalabala ezakha isitayela esiyingqayizivele nesemfashini. Kwezinye izinto zokukhanyisa ekhaya, ubuhlalu bengilazi obunemibala bungenza futhi isimo sokukhanya esifudumele, sothando, noma somlingo.
3. Umbala wobuhlalu bengilazi uthintwa yizici ezihlukahlukene. Umbala ocatshangelwayo ungahluka kuye nge-engeli yokubuka. Isibonelo, ubuhlalu bengilazi obuhlaza okwesibhakabhaka obubukwa nge-engeli ethile bungase bubonakale bunombala onsomi, ngenxa yokuhlukahluka kwama-engeli okukhanya nokukhanyela. Amandla okukhanya nawo anomthelela kumbala. Ngaphansi kokukhanya okunamandla, imibala yobuhlalu bengilazi ingase ibonakale ikhanya futhi iqine kakhulu; ezindaweni eziphansi-ezikhanyayo, imibala ingase ithambe futhi ibe mnyama. Lokhu kushintsha kombala okubangelwa izici zemvelo kwandisa ukwazisa kanye nesithakazelo sobuhlalu bengilazi, okuvumela abantu ukuba bathole ubuhle babo obuhlukene ezimeni ezahlukene.
