Ukukhanya kwelanga ebusuku kukhangeleka kwaye kukhangeleka njengelanga eliphumayo, ukukhanyisa ukufudumala kwintsapho; kukho iinguqulelo ezintathu zolawulo lokukhanya, isandi nolawulo lokukhanya, kunye nolawulo olukude;
uhlobo lokulawula ukukhanya: xa ukukhanya kubuthathaka, ukukhanya kobusuku kuya kuvula ngokuzenzekelayo , Xa ukukhanya kunamandla, kungena ngokuzenzekelayo kwimodi yokulinda.
Uhlobo lokulawula isandi kunye nokukhanya: Xa ukukhanya kubuthathaka, ukukhanya kobusuku kuya kukhanya ngokuzenzekelayo xa umthombo wesandi uphezulu kune-decibels ze-60, kwaye ngokuzenzekelayo ungene kwimodi yokulinda emva kwemizuzwana ye-60.
Uhlobo lolawulo olukude: Ukufiphala okungapheliyo kunye nemizuzu eli-10, imizuzu engama-30, kunye nemizuzu engama-60 yokusebenza kwexesha kunokuqhutywa ngokulawulwa kude. Ngelo xesha, nayo inomsebenzi wokulawula ukukhanya ukukhusela i-remote control ukuba ingalahleki okanye yonakaliswe ukuchaphazela ukusetyenziswa kwesibane.
