Ukukhanyisa kwe-LED kuhluke ku-incandescent kanye ne-fluorescent ngezindlela eziningana. Uma yakhelwe kahle, ukukhanya kwe-LED kusebenza kahle kakhulu, kuyaguquguquka, futhi kuhlala isikhathi eside.
Ama-LED ayimithombo yokukhanya “eqondile,” okusho ukuthi akhipha ukukhanya endaweni ethile, ngokungafani ne-incandescent ne-CFL, ekhipha ukukhanya nokushisa kuzo zonke izinhlangothi. Lokho kusho ukuthi ama-LED ayakwazi ukusebenzisa ukukhanya namandla ngendlela ephumelela kakhulu kuzinhlelo zokusebenza eziningi. Kodwa-ke, kusho nokuthi ubunjiniyela obuyindida buyadingeka ukukhiqiza isibani se-LED esikhanyisa yonke indawo.
Imibala ye-LED evamile ihlanganisa inhlaka, obomvu, oluhlaza okotshani, noluhlaza okwesibhakabhaka. Ukuze kukhiqizwe ukukhanya okumhlophe, ama-LED anemibala ehlukene ahlanganiswa noma ambozwe ngento ye-phosphor eguqula umbala wokukhanya ekukhanyeni okuvamile “okumhlophe” okusetshenziswa ezindlini. I-Phosphor yinto ephuzi evala amanye ama-LED. Ama-LED anombala asetshenziswa kakhulu njengezibani zesignali namalambu ezinkomba, njengenkinobho yamandla kukhompyutha.
Ku-CFL, amandla kagesi ageleza phakathi kwama-electrode ekugcineni kweshubhu eliqukethe amagesi. Lokhu kusabela kukhiqiza ukukhanya kwe-ultraviolet (UV) nokushisa. Isibani se-UV siguqulwa sibe ukukhanya okubonakalayo lapho sishaya i-phosphor coating ngaphakathi kwe-bulb.
Izibani ze-incandescent zikhiqiza ukukhanya zisebenzisa ugesi ukushisa umcu wensimbi kuze kube yilapho kushisa "mhlophe" noma kuthiwa i-incadesce. Ngenxa yalokho, izibani ze-incandescent zikhulula amandla angu-90% njengokushisa.
