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 bakuqhelile ukwahlula kwemibala phantsi kokukhanya kwelanga, ngoko xa bethelekisa unikezelo lombala, badla ngokuthatha umthombo wokukhanya owenziweyo kufutshane nommandla wokukhanya welanga njengomthombo wokukhanya oqhelekileyo, yaye okukhona umthombo wokukhanya usondela kwispectrum yokukhanya okukhona, kokukhona usiba phezulu isalathiso sombala obonisa umbala.
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. Kukukhanya okuphantsi kakhulu, ukukhanya okutofotofo ngumbala ophantsi wobushushu bombala kufutshane nedangatye, ekukhanyeni okuphantsi okanye okuphakathi, ukukhanya okutofotofo ngumbala wombala ophezulu kancinane kufutshane nokusa nokuhlwa, kwaye ekukhanyeni okuphezulu ngumbala ophezulu wobushushu bombala wesibhakabhaka kufutshane nemini yelanga okanye eluhlaza okwesibhakabhaka. Ke xa uyila indawo yangaphakathi yendawo eyahlukeneyo yokusingqongileyo, ukukhanya okufanelekileyo kombala kufuneka kukhethwe.
