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.
Unikezelo lombala lwemithombo eyenziweyo luxhomekeke ikakhulu kulwabiwo lwembonakalo yomthombo.Imithombo yokukhanya ene-spectrum eqhubekayo efana nokukhanya kwelanga kunye nezibane ze-incandescent zonke zinemibala emihle.Indlela edibeneyo yovavanyo yombala isetyenziselwa ukuyivavanya ekhaya nakwamanye amazwe.Isalathiso sobungakanani sisalathiso sophuhliso lombala (CRI), kubandakanywa isalathisi sophuhliso lombala jikelele (Ra) kunye nesalathisi esikhethekileyo sokuphuhlisa umbala (Ri).Isalathiso sonikezelo sombala jikelele siqhele ukusetyenziswa kuphela ukuvavanya isalathiso sombala esikhethekileyo sonikezelo, 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.
