Ekuphileni kwansuku zonke, abantu abaningi bacabanga ukuthi amandla ezibani ze-LED ahlobene ngokuqondile nokukhanya kwawo.Nokho, ukujula endabeni kuveza ukuthi akunjalo.Nakuba i-wattage idlala indima ekusetshenzisweni kwamandla nasekusetshenzisweni kukagesi, akuyona into ebalulekile ekunqumeni ukuthi ukukhanya kuzokhanya kangakanani.Esikhundleni salokho, isici esiyinhloko ukuguquguquka okukhanyayo.

Amandla akalwa ngama-watts (W) futhi amele umsebenzi owenziwe into ngesikhathi seyunithi ngayinye.Ukuphakama kwesilinganiso samandla, kukhulu ukusetshenziswa kwamandla namandla, kodwa lokhu kuyinkomba kuphela futhi akusona isicaciso esiyinhloko sokukhanya.Ngakolunye uhlangothi, ukugeleza okukhanyayo, okukalwa ngama-lumens (LM), kulinganisa inani lokukhanya iso lomuntu elingalibona ngeyunithi ngayinye.Ukuphakama kwesilinganiso se-lumen, ukukhanya okukhiphayo kugqame.

Ukuze ubale ukukhanya kwesibani, kufanele ucabangele ukusebenza kahle kokukhanya, kukalwa ngamalumens ngewathi ngayinye (LM/W).Imithombo yokukhanya ehlukahlukene enokukhanya okufanayo okuguquguqukayo kunokusetshenziswa kwamandla okuhlukile.Ukuphakama kokukhanya okukhanyayo, amandla amancane asetshenziswa ngaphansi kokukhanya okufanayo okuguquguqukayo.Ifomula yokubala ye-flux ekhanyayo i-flux ekhanyayo = ukusebenza kahle kokukhanya * amandla.

Isibonelo, cabangela izibani ezimbili: isibani esingu-36W esisebenza kahle ngokukhanyayo kwe-80lm/W sikhipha ukukhanya okukhanyayo okungu-2880lm, kanye nesibani esingu-30W esisebenza kahle ngokukhanyayo kwe-110lm/W sikhipha ukukhanya okukhanyayo okungu-3300lm.Kulesi sibonelo, nakuba isibani esingu-30W sinesilinganiso samandla aphansi, sikhanya kakhulu kunesibani esingu-36W ngenxa yokukhanya kwaso okuphezulu.

Kafushane, kusobala ukuthi ukukhanya okukhanyayo okunqunywa ukusebenza kahle okukhanyayo namandla kuyisici esiyinhloko esinquma ukukhanya kwesibani.Ukuqonda lo mehluko kungasiza abathengi benze izinqumo ezinolwazi lapho bekhetha izibani ze-LED ukuze bahlangabezane nezidingo zabo zokukhanyisa.
