Kunezinhlobo eziningi zemithombo yokukhanya, izici zazo ze-spectral zihlukile, ngakho-ke into efanayo emithonjeni yokukhanya ehlukene ye-irradiation, izobonisa imibala ehlukene, lokhu ukunikezwa kombala komthombo wokukhanya.
Ngokuvamile, abantu bajwayele ukuhlukaniswa kombala ngaphansi kokukhanya kwelanga, ngakho uma beqhathanisa ukunikezwa kombala, ngokuvamile bathatha umthombo wokukhanya wokwenziwa eduze ne-spectrum yokukhanya kwelanga njengomthombo wokukhanya ojwayelekile, futhi lapho umthombo wokukhanya usondelana ne-spectrum yokukhanya ejwayelekile, iba phezulu inkomba yayo yokunikeza umbala.
Izindawo ezifanelekile zezinkomba zokunikeza ngemibala ehlukene. Ezindaweni lapho imibala idinga ukukhonjwa ngokucacile, ingxube yemithombo yokukhanya eminingi ene-spectra efanelekile ingasetshenziswa.
Ukunikezwa kombala kwemithombo yokwenziwa ikakhulukazi kuncike kakhulu ekusabalaliseni okubonakalayo komthombo. Imithombo yokukhanya ene-spectrum eqhubekayo efana nokukhanya kwelanga namalambu e-incandescent yonke inokuhumusha okuhle kombala. Indlela yokuhlola ehlanganisiwe yombala isetshenziselwa ukuyihlola ekhaya naphesheya. Inkomba yobuningi inkomba yokuthuthukiswa kombala (CRI), okuhlanganisa inkomba evamile yokuthuthukiswa kombala (Ra) kanye nenkomba ekhethekile yokuthuthukisa umbala (Ri). Inkomba evamile yokunikeza umbala ngokuvamile isetshenziswa kuphela ukuhlola inkomba ekhethekile yokunikeza umbala, esetshenziselwa kuphela ukuphenya ukunikezwa kombala komthombo wokukhanya olinganiselwe kumbala wesikhumba somuntu. Uma inkomba evamile yokunikeza umbala yomthombo wokukhanya okufanele ikalwe iphakathi kuka-75 no-100, inhle kakhulu; futhi phakathi kuka-50 no-75, ngokuvamile impofu.
Ukunethezeka kwezinga lokushisa lombala kunobudlelwane obuthile nezinga lokukhanyisa. Ekukhanyeni okuphansi kakhulu, ukukhanya okunethezekile kuwumbala ophansi wokushisa wombala oseduze nelangabi, ekukhanyeni okuphansi noma okumaphakathi, ukukhanya okunethezekile kuwumbala wombala othe ukukhuphuka kancane eduze kokuntwela kokusa nokuhwalala, futhi ekukhanyeni okuphezulu umbala wesibhakabhaka onemibala ephezulu eduze nokukhanya kwelanga phakathi nemini noma eluhlaza okwesibhakabhaka. Ngakho-ke lapho uklama isikhala sangaphakathi somkhathi wemvelo ohlukile, ukukhanya okufanelekile kombala kufanele kukhethwe.
