CCT
CCT imatanthauzidwa mu madigiri Kelvin; kuwala kotentha kumakhala kozungulira 2700K, kusuntha kuyera kopanda ndale kuzungulira 4000K, ndikuzizira koyera, pa 5000K kapena kupitilira apo.
Kuwala kowala
Mu photometry, kamwazi wowala or mphamvu yowala ndiye muyeso wa mphamvu yozindikiridwa ya kuwala. Zimasiyana ndi kuwala kowala, muyeso wa mphamvu yonse ya ma radiation a electromagnetic (kuphatikizapo infrared, ultraviolet, ndi kuwala kowoneka), mu kuwala kowala komweko kumasinthidwa kuti ziwonetsere kukhudzidwa kwa diso la munthu ku mafunde osiyanasiyana a kuwala.
Gawo la SI la luminous flux ndi kuwala (lm). Lumen imodzi imatanthauzidwa ngati kuwala kwa kuwala komwe kumapangidwa ndi gwero la kuwala komwe kumatulutsa kandulo imodzi ya mphamvu yowala kwambiri pa ngodya yolimba ya steridian imodzi.
Mu machitidwe ena a mayunitsi, kuwala kowala kumatha kukhala ndi mayunitsi amphamvu.
