Izibani zophahla ziyisici esibalulekile kunoma iyiphi indawo eklanywe kahle, ehlinzeka kokubili ukusebenza nokukhanga kobuhle.Phakathi kwezinketho ezihlukahlukene ezitholakalayo, ukukhanya kwentaba okushaywayo kugqama njengokukhetha okuthandwayo.Okuhlukile okukodwa, ukukhanya kophahla lwekristalu, kwengeza ukuthinta kobuhle nobunkimbinkimbi kunoma yiliphi igumbi.
Lokhu kukhanya okuhle ophahleni, okuklanyelwe ngokukhethekile amagumbi okulala, kunobubanzi obungu-60cm nokuphakama okungama-40cm, okuyenza ifaneleke kahle izindawo ezimaphakathi.Ngamalambu ayo ayisithupha, ikhanyisa igumbi ngokulinganayo, idale indawo efudumele nekhangayo.Uhlaka lwensimbi, luqinile futhi luhlala isikhathi eside, luqinisekisa ukuphila isikhathi eside, kuyilapho amakristalu athuthukisa kahle ukwakheka kwawo wonke, abonisa ukukhanya futhi asakaza amaphethini amahle ezindongeni.
Ukuguquguquka kwalokhu kukhanya ophahleni kungesinye isici esiphawulekayo.Ilungele izindawo eziningi, okuhlanganisa igumbi lokuphumula, igumbi lokudlela, igumbi lokulala, ikhishi, iphasishi, ihhovisi lasekhaya, ngisho nehholo ledili.Idizayini yayo engaphelelwa yisikhathi ihlangana ngaphandle komthungo nezitayela zangaphakathi ezahlukahlukene, kungaba ezesimanjemanje, ezesimanje noma ezendabuko.
Ekamelweni lokuphumula, lokhu kukhanya kosilingi kuba indawo okugxilwe kuyo, okwengeza ukuthinta kobukhazikhazi esikhaleni.Egunjini lokudlela, kwakha umoya osondelene, olungele izivakashi ezijabulisayo.Ekamelweni lokulala, likhipha umuzwa wokunethezeka nokuthula, okwandisa ukuphumula.Ekhishini, kunikeza ukukhanya okwanele kokulungiselela ukudla.Ephasishi, iqondisa indlela ngokukhanya kwayo okukhazimulayo.Ehhovisi lasekhaya, lengeza ukuthinta kokuyinkimbinkimbi, ukukhiqiza okukhuthazayo.Futhi ehholo ledili, ibeka inkundla yemikhosi emikhulu.
