Ubomi bemihla ngemihla, abaninzi abantu bacinga ukuba amandla ezibane ze-LED zihambelana ngqo nokukhanya kwazo. Noko ke, xa siwuhlolisisa ngokunzulu lo mbandela sifumanisa ukuba akunjalo. Ngelixa i-wattage idlala indima ekusetyenzisweni kwamandla kunye nokusetyenziswa kombane, ayisiyiyo eyona nto iphambili ekumiseleni ukuba ukukhanya kuya kuqaqamba kangakanani. Endaweni yoko, eyona nto iphambili yi-flux ekhanyayo.

Amandla alinganiswa ngeewatts (W) kwaye amele umsebenzi owenziwe yinto nganye ngexesha leyunithi. Okukhona umlinganiselo wamandla uphezulu, kokukhona amandla amakhulu kunye nokusetyenziswa kwamandla, kodwa le yinkalo yesalathiso kuphela kwaye ayisiyiyo eyona nto iphambili yokuqaqamba. Ngakolunye uhlangothi, i-luminous flux, elinganiswe kwi-lumens (LM), ichaza ubungakanani bokukhanya ukuba iliso lomntu linokubona kwindawo nganye yeyunithi. Okukhona umlinganiselo welumen uphezulu, kokukhona kuqaqamba ngakumbi ukukhanya.

Ukubala ukukhanya kwesibane, kufuneka uqwalasele ukukhanya kokukhanya, kulinganiswe kwi-lumens nge-watt (LM / W). Imithombo eyahlukeneyo yokukhanya enokukhanya okukhanyayo okufanayo kunokusetyenziswa kwamandla okwahlukileyo. Ukuphakama kokusebenza okukhanyayo, amandla amancinci asetyenziswa phantsi kwe-flux efanayo ekhanyayo. Ifomyula yokubala ye-luminous flux yi-luminous flux = ukukhanya okusebenzayo * amandla.

Ngokomzekelo, qwalasela izibane ezibini: isibane se-36W esinobuchule obukhanyayo be-80lm / W sikhupha i-flux ekhanyayo ye-2880lm, kunye nesibane se-30W esinokukhanya okukhanyayo kwe-110lm / W sikhupha i-flux ekhanyayo ye-3300lm. Kulo mzekelo, nangona isibane se-30W sinomlinganiselo ophantsi wamandla, sikhanya ngakumbi kunesibane se-36W ngenxa yokukhanya okuphezulu okukhanyayo.

Isishwankathelo, kuyacaca ukuba ukukhanya okukhanyayo okugqitywe ngokusebenza okukhanyayo kunye namandla yeyona nto iphambili emisela ukukhanya kwesibane. Ukuqonda lo mahluko unokunceda abathengi benze izigqibo ezinolwazi xa bekhetha izibane ze-LED ukuhlangabezana neemfuno zabo zokukhanyisa.
