I-CCT
I-CCT ichazwa ngamadigri Kelvin; ukukhanya okufudumele kuzungeze u-2700K, kuya kokumhlophe okuphakathi nendawo cishe ku-4000K, futhi kuphole kumhlophe, ku-5000K noma ngaphezulu.
Ukuphazamisa okukhanyayo
Ku-photometry, ukukhanya okukhanyayo or amandla akhanyayo isilinganiso samandla okukhanya abonwayo. Ihlukile i-radiant flux, isilinganiso samandla esewonke emisebe kazibuthe (okuhlanganisa i-infrared, i-ultraviolet, nokukhanya okubonakalayo), kulokho kuguquguquka okukhanyayo kulungiswa ukuze kubonise ukuzwela okuhlukahlukene kweso lomuntu kumaza ahlukene okukhanya.
Iyunithi ye-SI ye-flux ekhanyayo yi- i-lumen (lm). I-lumen eyodwa ichazwa njengokuguquguquka okukhanyayo kokukhanya okukhiqizwa umthombo wokukhanya okhipha ikhandlela elilodwa lokuqina okukhanyayo phezu kwe-engeli eqinile ye-steridian eyodwa.
Kwezinye izinhlelo zamayunithi, i-flux ekhanyayo ingaba namayunithi amandla.
