Izibane ze-LED zahlukile kwi-incandescent kunye ne-fluorescent ngeendlela ezininzi. Xa yenzelwe kakuhle, ukukhanya kwe-LED kusebenza ngakumbi, kubhetyebhetye, kwaye kuhlala ixesha elide.
Ii-LEDs ziyimithombo yokukhanya "esalathisa", oko kuthetha ukuba zikhupha ukukhanya kwicala elithile, ngokungafaniyo ne-incandescent kunye neCFL, ekhupha ukukhanya nobushushu kuwo onke amacala. Oko kuthetha ukuba ii-LEDs ziyakwazi ukusebenzisa ukukhanya namandla ngokufanelekileyo kwisininzi sezicelo. Nangona kunjalo, kukwathetha ukuba ubunjineli obunobunkunkqele buyafuneka ukuvelisa ibhalbhu yesibane se-LED ekhanya kwicala ngalinye.
Imibala eqhelekileyo ye-LED ibandakanya i-amber, ebomvu, eluhlaza kunye nohlaza okwesibhakabhaka. Ukuvelisa ukukhanya okumhlophe, ii-LEDs zemibala eyahlukeneyo ziyadityaniswa okanye zigutyungelwe ngezinto ze-phosphor eziguqula umbala wokukhanya kukukhanya okuqhelekileyo "okumhlophe" okusetyenziswa emakhayeni. I-Phosphor yinto etyheli egubungela ii-LEDs ezithile. Ii-LED ezinemibala zisetyenziswa ngokubanzi njengezibane zomqondiso kunye nezibane zesalathi, njengeqhosha lamandla kwikhompyuter.
Kwi-CFL, amandla ombane ahamba phakathi kwee-electrode kwisiphelo setyhubhu nganye eneegesi. Le mpendulo ivelisa ukukhanya kwe-ultraviolet (UV) kunye nobushushu. Ukukhanya kwe-UV kuguqulwa kube kukukhanya okubonakalayo xa kubetha ukutyabeka kwe-phosphor ngaphakathi kwebhalbhu.
Iibhalbhu ze-incandescent zivelisa ukukhanya kusetyenziswa umbane ukufudumeza intambo yentsimbi ide ibe "mhlophe" ishushu okanye kuthiwe yi-incandesce. Ngenxa yoko, iibhalbhu ze-incandescent zikhupha i-90% yamandla abo njengobushushu.
