Izinga lokukhanya liyinkomba ebalulekile yamalambu asetshenziswa empilweni yansuku zonke. Kubandakanya izici eziningi.

Izici ezinjalo ezinjengokuhlanzeka, ukugcwala kanye nokunemba kombala kufaka zombili ukukhanya okupeyintiwe nokumhlophe. Izici ezimbili eziphambili zekhwalithi yokukhanya okumhlophe ukushisa kombala kanye nenkomba yokunikeza imibala.
I-Colour Relition Index ikhombisa ukuthi umthombo wokukhanya udlulisa kahle kangakanani imibala yezinto ezikhanyisiwe. Ibonisa amandla womthombo wokukhanya ngokudlulisela imibala yezinto ezahlukahlukene uma uqhathanisa nomthombo ophelele wokukhanya. Le pharamitha iyinkomba yekhwalithi yekhwalithi yemibala yemibala esikalini sika-0 kuye ku-100 futhi ihambelana nenani lezinkomba le-100.

Ekusebenzeni, kusetshenziswa ukuhlolwa ukukala ukuthi imibala yamasampula anemibala ajwayelekile ayisishiyagalombili aqokwe, ushintsho lapho kukhanyiswa ngumthombo wokukhanya okuhlobene nokukhanya komthombo wokukhanya kwesethenjwa. Imibala yamasampula ayisishiyagalombili inokugcwala okuphansi kakhulu futhi isatshalaliswa ngokulinganayo kulo lonke uhla lwethoni.
Inani eliphansi elamukelekayo le-Light Sourdiac Colour Regsogemermeruction Index incike emkhakheni wohlelo lokusebenza lwayo:
- Inani le-Index yokuzala kabusha yombala ohlwini lwama-90-100 adingekayo ezindaweni lapho ukuhumusha umbala ngqo kubalulekile - ngokwesibonelo, kugalari yezobuciko.
- Ngezakhiwo eziningi zokuhlala, inkomba yokuhlelwa kombala akumele ibe ngaphansi kwama-70-90.
I-Color Rendering Index ikhonjiswa ngokupakishwa kwesibani.
Ukushisa kombala kukhombisa ukuthi umbala omhlophe uthathwa kanjani: ukufudumala (okubomvu), ukungathathi hlangothi noma ukubanda (bluesh). Kukalwa ngama-degrees of kelvin (k), lapho okushisa ngokuphelele kulinganiswa. Ngokwandisa izinga lokushisa lomzimba omnyama, umbala wokuphuma kokukhanya okukhishwe yizo ngokulandelayo: Red - Orenji - Ophuzi - Okwephuzi - okuluhlaza okwesibhakabhaka. Ifana nengxenye yensimbi efudumeza entabeni yeBlacksmith.

Isibani se-incandescent sikhipha ukukhanya ngokushisa kombala cishe cishe ngo-2700 k, okuyindawo efudumele noma ebomvu yesikhala sombala. Kusukela ngesibani se-incandescent, intambo iyasetshenziswa, okufuthelwe lapho imisebe ekhanyayo, izinga lokushisa lentambo lingamazinga okushisa anemibala.
Amazinga okushisa athile wombala ahambelana nokukhanya kusuka ekufudumele kuya kubanda kuhlotshaniswa nemithombo ethile yokukhanya kanye nomhlobiso. Ukushisa kombala kuthinta nemiphumela engokomzwelo yesikhala futhi kungashintsha ngokuqinile ukubukeka kwezinto.
