Ukukhanya kwe-LED kuyahluka kwi-incandescent kunye ne-fluorescent ngeendlela ezininzi.Xa iyilwe kakuhle, ukukhanya kwe-LED kusebenza ngakumbi, kuyaguquguquka, kwaye kuhlala ixesha elide.
Ii-LED ziyimithombo yokukhanya "yezikhokelo", oku kuthetha ukuba zikhupha ukukhanya kwindlela ethile, ngokungafani ne-incandescent kunye ne-CFL, ekhupha ukukhanya kunye nokushisa kuzo zonke iindlela.Oko kuthetha ukuba ii-LED ziyakwazi ukusebenzisa ukukhanya kunye namandla ngokufanelekileyo kubuninzi bezicelo.Nangona kunjalo, kukwathetha ukuba ubunjineli obuphucukileyo buyadingeka ukuvelisa ibhalbhu yokukhanya ye-LED ekhanyisa ukukhanya macala onke.
Imibala eqhelekileyo ye-LED ibandakanya i-amber, ebomvu, eluhlaza, kunye neblue.Ukuvelisa ukukhanya okumhlophe, ii-LED zombala ohlukeneyo zidibaniswe okanye zigutyungelwe ngezinto ze-phosphor eziguqula umbala wokukhanya kwisibane esiqhelekileyo "esimhlophe" esisetyenziswa kumakhaya.Iphosphor yinto etyheli egquma ezinye ii-LED.Ii-LED ezinemibala zisetyenziswa ngokubanzi njengezibane zesignali kunye nezibane zesalathisi, njengeqhosha lamandla ekhompyutheni.
Kwi-CFL, umsinga wombane uhamba phakathi kwe-electrode ekupheleni kwetyhubhu equkethe iigesi.Oku kusabela kuvelisa ukukhanya kunye nobushushu be-ultraviolet (UV).Isibane se-UV siguqulwa sibe kukukhanya okubonakalayo xa sibetha i-phosphor coating ngaphakathi kwebhalbhu.
Iibhalbhu ze-incandescent zivelisa ukukhanya ngokusebenzisa umbane ukutshisa i-filament yesinyithi de ibe "mhlophe" shushu okanye kuthiwa i-incandesce.Ngenxa yoko, ii-incandescent bulbs zikhupha i-90% yamandla azo njengobushushu.
