Kukho iintlobo ezininzi zemithombo yokukhanya, iimpawu zabo ze-spectral zihluke, ngoko ke into efanayo kwimithombo eyahlukeneyo yokukhanya kwe-irradiation, iya kubonisa imibala eyahlukileyo, oku kukunikezelwa kombala komthombo wokukhanya.
Ngokuqhelekileyo, abantu baqhele ukuhlula umbala phantsi kokukhanya kwelanga, ngoko ke xa bethelekisa unikezelo lombala, badla ngokuthatha umthombo wokukhanya owenziweyo kufutshane nokukhanya kwelanga njengomthombo wokukhanya oqhelekileyo, kwaye ngokukhona umthombo wokukhanya ukufutshane kukukhanya okuqhelekileyo, kokukhona iphezulu isalathiso sombala wayo.
Iindawo ezifanelekileyo zonikezelo lwemibala eyahlukileyo. Kwiindawo apho imibala idinga ukuchongwa ngokucacileyo, umxube wemithombo yokukhanya emininzi kunye ne-spectra efanelekileyo ingasetyenziswa.
Ukunikezelwa kombala kwemithombo eyenziweyo ikakhulu kuxhomekeke ikakhulu kulwabiwo lwembonakalo yomthombo. Imithombo yokukhanya ene-spectrum eqhubekayo efana nokukhanya kwelanga kunye nezibane ze-incandescent zonke zinemibala emihle. Indlela yokuvavanya umbala odibeneyo isetyenziselwa ukuyivavanya ekhaya nakwamanye amazwe. Isalathisi sobungakanani yisalathisi sophuhliso lombala (CRI), kubandakanywa nesalathisi sophuhliso lombala jikelele (Ra) kunye nesalathiso esikhethekileyo sophuhliso lombala (Ri). Unikezelo lombala jikelele lwesalathiso ludla ngokusetyenziswa kuphela ukuvavanya isalathiso esikhethekileyo sonikezelo sombala, esisetyenziselwa kuphela ukuphanda unikezelo lombala womthombo wokukhanya olinganiselweyo kumbala wolusu lomntu. Ukuba isalathiso sombala jikelele wonikezelo lomthombo wokukhanya oza kulinganiswa siphakathi kwe-75 kunye ne-100, sisemagqabini; kwaye phakathi kwama-50 nama-75, lihlwempuzekile ngokubanzi.
Ukuthuthuzela kobushushu bombala kunobudlelwane obuthile kwinqanaba lokukhanyisa. Ekukhanyeni okuphantsi kakhulu, ukukhanya okukhululekileyo ngumbala ophantsi wobushushu bombala kufuphi nedangatye, ekukhanyeni okuphantsi okanye okuphakathi, ukukhanya okukhululekile ngumbala wombala ophezulu kancinane kufuphi nokusa nokuhlwa, kwaye ekukhanyeni okuphezulu ngumbala ophezulu wokushisa kwesibhakabhaka umbala kufuphi nokukhanya kwelanga emini okanye luhlaza. Ke xa uyila indawo yangaphakathi yendawo eyahlukeneyo yokusingqongileyo, ukukhanya okufanelekileyo kombala kufuneka kukhethwe.
