Lokacin da abokin ciniki ke nufin CCT tare da matakin SDCM, kuna samun jagora don samar musu da ingantaccen launi mai haske. Misali, abokin ciniki yana buƙatar haske na 3000K-3300K tare da SDCM ƙasa da 5 kamar yadda ƙa'idodin Turai.
Yanzu, bisa ga ma'aunin IEC 60081, 3000K-3300K don 5-mataki SDCM ya faɗi ƙarƙashin jeri biyu. Don 3000K, shine (2820-3070K). Anan, zaku sami zaɓi na CCT na 70K kawai (3000K-3070K). Hakanan, don 3500K, kewayon mataki 5 shine 3280-3630K. Anan, zaɓin bambancin CCT shine kawai 20K (3280-3300K). Don haka, hasken da kuke ba abokin ciniki dole ne ya faɗi ƙarƙashin wannan kewayon.
