Isibane seLampu yokuKhanya kweLampu yokuKhanya kweR40 ubukhulu becala sisetyenziselwa ukufuya amantshontsho ehagu, ukufuya iinkukhu, njlnjl. evunyiweyo ukuba yindlela efanelekileyo yokunciphisa izinga lokufa kwezilwanyana elibangelwe ngumkhenkce ebusika. Amandla aphezulu elayini ebomvu ye-R40 yebhalbhu yebhalbhu yokukhanya inokufikelela kwi-375W, enokuvelisa ubushushu obuninzi ukuze isilwanyana sigcine ukufudumala. ngaphandle koko, i-R40 ebomvu yesibane sokukhanya esenziwe ngeglasi elukhuni, iglasi elukhuni bubungqina obuphakathi.

Ukuba ufakela isibane esibomvu sobushushu esibubushushu obungama-r40 kwisibane sesibane, nceda uqinisekise ukuba umbane webhalbhu yobushushu obomvu obungu-r40 awubikho ngaphezulu kwamandla ombane aphezulu awamkelekileyo wesibane sesibane seso. Ngaphandle koko, i-r40 ebomvu yokukhanya kwesibane sokukhanyisa iya kuphuka ngenxa yentloko.
