1. Ukukhanya kokukhanya kobufakazi
Lesi sigaba sifaka izibani ze-fluorescent zokuqhuma, izibani zezikhukhula, izibani, izibani zokungeniswa, izibani ezivalekile, Izibani ze-LED, izibani zesikhulumi, izibani zomgwaqo, futhi nokuningi.
2. Izibani eziphuthumayo zokwenza ubufakazi
Ngokuyinhloko esetshenziselwa izimo eziphuthumayo ezindaweni ezivuthayo neziqhumayo, leli qembu lihlanganisa izimpawu zokuphuma ezingaqhumi nezibani eziphuthumayo phakathi kokunye.
3. Izibani zesiginali
Lokhu kusetshenziselwa ikakhulukazi ukusayina ezindaweni ezivuthayo neziqhumayo futhi kufaka amalambu we-alamu wokuhlekisa nokubukwayo, Izibani zesiginali yendiza, futhi nokuningi.
4. Ukuqhuma kobufakazi kanye namalambu alwa nokugqwala
Yakhelwe izindawo ezithambekele emlilweni, ukuthi qhu, kanye nokugqwala okuqinile, Izinketho zifaka amalambu wokulwa nokuvikeleka wokulwa nokuqina, Izibani zensimbi ezingenasici zokulwa nobufakazi, nabanye.
