Ukukhanya kwengadi yelanga kuyithuluzi lokukhanyisa langaphandle elisebenzisa amandla elanga ukushaja nokunikeza ukukhanya ebusuku. Lolu hlobo lwesibani luvame ukuba namaphaneli elanga, izibani ze-LED noma amabhalbhu okukhanyisa okonga amandla, amabhethri kanye nezifunda zokulawula. Emini, amaphaneli elanga amunca ukukhanya kwelanga futhi agcine amandla emabhethrini, kanti ebusuku ahlinzeka ngokukhanya ngokulawula isifunda ukuze kukhanyise izibani ze-LED noma amabhalbhu okonga amandla.

Njengamanje, izibani zengadi zelanga zithuthuka kahle emakethe. Njengoba abantu benaka kakhulu amandla aluhlaza anobungani nemvelo, izibani zengadi zelanga ziyathandwa kancane kancane ngabathengi njengenketho yokukhanyisa okonga amandla nobungani nemvelo. Izibani zengadi zelanga zezitayela nemisebenzi eyahlukene nazo ziyavela emakethe, zihlangabezana nezidingo zabathengi ezahlukahlukene zokukhanyisa kwangaphandle.

Abathengi bathanda kakhulu izibani zengadi zelanga. Banombono omuhle ngale mishini yokukhanyisa yangaphandle eyonga amandla, enobungani nemvelo, elula futhi ewusizo. Izibani zengadi zelanga azigcini nje ngokunikeza ukukhanya okwanele ezindaweni zangaphandle, kodwa futhi zigcina izindleko zamandla, ngakho-ke zamukelwa kabanzi.

Ngokuvamile, izibani zengadi zelanga okwamanje zisesigabeni sokuthuthuka okukhulu, futhi abathengi banokukhetha okukhulu kuzo. Ngokuthuthuka okuqhubekayo kobuchwepheshe kanye nokusungulwa komkhiqizo okuqhubekayo, izibani zengadi zelanga kulindeleke ukuthi ziqhubeke nokuthandwa emakethe esikhathini esizayo.
